A BEGINNER’S GUIDE TO FUNDAMENTAL ANALYSIS

Read the business.
Then read
the price.

A stock is a slice of a business. Its financial statements tell you what that business earns, where the money goes, and what it owes. The price tells you what you must pay for your slice.

01 / THE ACCOUNTING FOUNDATION

Three sheets.
One connected story.

The income statement and cash flow statement are movies: they cover a quarter or a year. The balance sheet is a photograph: it captures the company at one date. Read all three together. [3]

Dotted terms explain the accounting. Ratios below highlight the relevant statement rows. Full glossary ↓

AN ORIGINAL TEACHING EXAMPLE

Coffee shop: $10.00k monthly revenue, $120.00k annual sales. It begins with $60.00k from owners and a $30.00k loan, buys $24.00k of equipment and $6.00k of inventory, and has $60.00k beginning cash. The default example is fictional.

02 / FOLLOW ONE TRANSACTION THROUGH ALL THREE

Profit and cash
keep different clocks.

records revenue when earned and expenses when incurred, subject to accounting rules. A customer’s payment date can be different. That is why you need a cash flow statement alongside the income statement.

One event can affect three statements in different ways.

is money tied up in operations.

Receivables and inventory use cash as they grow. Supplier payables and customer advances can provide cash as they grow. Fast sales growth can consume cash when collections lag. Watch the business’s collection, inventory, and payment cycle.

“Noncash” does not mean “free.”

Depreciation reflects earlier capital spending; equipment will eventually need replacement. Stock compensation gives employees an ownership claim. A company can report strong cash flow while diluting existing owners.

03 / CONNECT ACCOUNTING TO THE PRICE TAG

Buy the equity.
Value the enterprise.

Accounting shows the results and resources. A valuation asks what future cash flows are worth, given growth, risk, and the return you require. A great business can still be a poor investment at an excessive price.

ASSUMED VALUE / SHARE$2.71k

One hypothetical ownership slice.

ILLUSTRATIVE SHARES100

The number of equal slices.

$270.72k

12× the default annual net profit.

Continue the default coffee shop: $22.56k annual profit × an assumed 12 P/E = $270.72k equity value. At exactly $2,707.20 per illustrative share, 100 shares have that value; $2.71k above is rounded. This is a private-business assumption, not a market quote. Its $76.56k book equity is a separate accounting number. A 2-for-1 split would mean 200 shares valued at $1,353.60 each, with the same total value.

SIMPLIFIED ENTERPRISE VALUE · DEFAULT COFFEE SHOP · USD $K

$270.72k+$30k−$63.36k=$237.36k

Buying the shareholders’ claim also leaves the lenders’ claim to be dealt with. Cash acquired with the business can offset that cost. This simplified arithmetic assumes all cash is surplus and available. It uses the default model, while the selector and editable row follow your current inputs.

Why add debt?

Two companies can have the same operating business but different financing. Comparing only market cap can make the company with more debt appear cheaper. EV brings debt back into the price you are paying for the business.

Debt is not all liabilities. Payables, deferred revenue, and tax liabilities are not automatically added as funded debt. They belong in your operating and risk analysis.

Why subtract cash?

Surplus cash is a non-operating asset you receive alongside the business. Cash needed for payroll, restricted cash, and volatile investments require separate judgment.

A fuller EV calculation can add preferred equity and noncontrolling interests, include consistent lease adjustments, and subtract excess cash and other non-operating assets. Debt’s market value can differ from book value.

EQUITY ↔ OWNERS’ PROFIT

Price ÷ diluted EPS
or equity value ÷ owners’ earnings

How much you pay per dollar of annual earnings. A low multiple may reflect slow growth, cyclically high profits, risk, or a temporary gain. Negative earnings make the usual P/E unhelpful.

EQUITY ↔ CASH AFTER CAPEX

&

Market cap ÷ FCF
FCF yield = FCF ÷ market cap

What remains after cash reinvestment relative to equity price. FCF is not necessarily distributed to owners. Debt repayment, acquisitions, and dilution can change the owner’s outcome.

ENTERPRISE ↔ OPERATIONS

Enterprise value ÷ EBIT
or enterprise value ÷ EBITDA

Match a price including lenders to earnings before interest. EBIT retains depreciation; EBITDA removes it. Compare consistent definitions and capital requirements.

ENTERPRISE ↔ SALES

Enterprise value ÷ revenue

Available even when profits are negative, but it hides margins. At 10× sales, a 5% operating margin means 200× EBIT; a 50% margin means 20× EBIT.

EQUITY ↔ BOOK CAPITAL

Market cap ÷ book equity

Compares market expectations with the accounting net assets. Buybacks, internally built brands, and expensed R&D complicate it. Book value is not a sale or liquidation value.

DEBT ↔ REPAYMENT CAPACITY

Debt ÷ EBITDA
Interest coverage = EBIT ÷ interest expense

Debt/EBITDA is a scale comparison, not literal years to repay: EBITDA has not paid tax or capex. Check cash, maturities, covenants, and whether earnings can survive a downturn.

KEEP THE NUMERATOR AND DENOMINATOR ON THE SAME SIDE

Market cap ↔ profit and cash available to equity.
Enterprise value ↔ operating earnings and cash available to all capital providers.

EV/net income mixes an all-provider price with after-interest earnings. Likewise, OCF − capex is a convenient U.S. GAAP cash measure after cash interest; it is not automatically unlevered free cash flow to the firm.

Where discounted cash flow fits

Estimate cash flows for future years, discount them at a rate reflecting their risk, and add a carefully justified continuing value. The important inputs are future sales, margins, reinvestment, and financing—not a ratio alone.

translates future cash into today’s value.

Firm value ≈ Σ FCFFt ÷ (1 + WACC)t + discounted continuing value

is cash to all capital providers: roughly after-tax operating profit + noncash charges − capex − additional operating working capital. is the weighted cost of debt and equity. Convert firm value to equity value by subtracting debt and other senior claims and adding non-operating assets; divide by diluted shares. Forecasts and terminal assumptions can dominate the answer, so use scenarios.

04 / PROFITABILITY HAS AN OPPORTUNITY COST

What did the capital
actually earn?

Making a profit is only the first hurdle. Capital could earn a return somewhere else. Damodaran’s lesson is to compare the business’s return on invested capital with the cost of that capital. [2]

≈ EBIT × (1 − normalized tax rate)

NOPAT means net operating profit after tax. It is measured before interest, so it belongs to both lenders and shareholders.

A common starting point for invested capital is book equity + interest-bearing debt − excess cash and non-operating assets. Another is operating working capital + net operating fixed assets. Average beginning and ending capital, and make consistent lease, acquisition, goodwill, and R&D adjustments.

$2m
20%
10%
Excess return10 pp

Economic profit ≈ (20% − 10%) × $10m = $1m. Accounting profit is positive; the return also exceeds the required return on capital.

High ROIC gives growth a purpose.

Reinvesting $1 at a return above its cost can create value. Reinvesting below that cost can destroy value even while sales and accounting profits grow. In a stable model, growth ≈ reinvestment rate × incremental ROIC: reinvesting 50% at 20% could support 10% operating-profit growth.

That is a model relationship, not a forecast. The return on the next dollar can be very different from historical average ROIC.

ROIC is a business return, not your stock return.

Its denominator is operating capital, not market cap. A business can earn a high ROIC while you earn a low return because you paid too much. ROE uses after-interest net income over book equity and can be boosted by debt or a small equity base.

Expensing research can understate invested capital; buybacks shrink book equity; goodwill and recent acquisitions change the denominator. There is no single universally comparable reported ROIC.

Model assumptions and why the margin has a range

All flows cover one hypothetical year. Ingredients cost 40% of sales; depreciation is 4%; annual loan interest is 2.5%; tax is 20% of positive pretax profit, with no tax credit for losses. Cash operating costs adjust to achieve your net margin. Capex is 10%, new receivables 5%, inventory 5%, and dividends 5% of sales. Beginning cash and original owner capital are each 50% of sales; original debt is 25% and equipment is 20%. These assumptions keep all three sheets reconciled.

Net margin is limited to −20%–42.8% so this particular model retains nonnegative cash and operating costs. P/E-based value is N/M with zero or negative profit; P/S can still assign a positive assumed value. These are chosen scenarios, not typical coffee shop economics or a business appraisal. Editing sales scales the opening balances as well as the year’s activity.

Now connect the business to what you pay.

Multiples are “times” (×), yields are annual cash divided by equity value. N/M means a positive earnings or cash multiple is not meaningful because the denominator is zero or negative.

*P/E proxy: estimated market cap ÷ consolidated GAAP net income. This is not quoted price ÷ reported diluted EPS: current shares differ from weighted-average diluted shares, and common-share allocations may differ. The same equity estimate is used for P/FCF and P/B. FCF yield is not a promised payout or total investment return.

What the numbers make you investigate.

These are analytical questions, not stock rankings or buy/sell signals. A multiple describes the market’s price relative to a particular denominator; it does not prove the denominator will persist.

TSLATesla[4]

A large price tag on a thin current profit base.

Operating margin is 4.2% and the P/E proxy is 388.0×. Separate current vehicle and energy earnings from expectations about future businesses; examine margins, capex, stock compensation, and share issuance.

NVDANVIDIA[5]

Strong margins; look beyond the narrow capex line.

Operating margin is 65.2%. Productive-asset capex is a small fraction of OCF, but acquisitions, other-company investments, supplier commitments, concentration, and noncash gains still matter.

GOOGAlphabet[6]

Headline earnings and operating economics diverge.

TTM net income exceeds operating income; first-half securities gains were $135.8bn. Compare the 17.3× P/E proxy with 28.8× EV/EBIT. Gross cash capex absorbs much of OCF; normalize gains and test infrastructure returns.

SPCXSpaceX[7]

Cash on hand and cash generated are different.

The group has $93.5bn cash and $38.3bn funded debt at June 30, but TTM FCF is about −$32.3bn. IPO financing does not become operating earnings. Separate Space, Connectivity, and AI economics.

AAPLApple[8]

Cash generation is strong; book equity tells a partial story.

About $136.7bn of this FCF measure accompanies a much larger market valuation. Buybacks and unrecognized internally built assets complicate the 45.7× price/book ratio; examine cash returns, debt, and share count.

MUMicron[9]

Normalize a capital-intensive business across its cycle.

The 14.1× earnings multiple depends on the durability of exceptionally strong fiscal-year profits. Gross capex of $30.7bn precedes $3.3bn of government incentives, so this FCF differs from the company’s adjusted measure. Test a downturn.

TTM construction. For interim reports: latest completed fiscal year + current fiscal year-to-date − the comparable prior-year year-to-date. The income and cash-flow windows end on the same stated date. This avoids multiplying a single seasonal quarter by four. Micron uses its complete 53-week FY2026 rather than the older May quarter.

SpaceX. TTM inputs combine its 2025 consolidated statements in the IPO prospectus with first-half 2026 and first-half 2025 in the 10-Q. This is the filing’s combined company history, including the AI group, rather than a history of publicly traded SpaceX shares. Nasdaq SPCX began trading in June 2026; the old ETF that used this ticker is a different security.

Debt and cash. Funded debt uses disclosed totals or current + noncurrent borrowing plus commercial paper. Tesla includes both current and noncurrent debt. SpaceX uses disclosed debt principal; Micron’s combined debt includes finance leases. Other lease liabilities, minority interests, preferred claims, securities investments, and cash restrictions are not adjusted in this simplified EV. These omissions make it different from a fully adjusted acquisition value or vendor EV.

Cash capital spending. NVIDIA’s productive-asset purchase line includes property/equipment and intangible assets. SpaceX’s separate capitalized interest and rebates, Micron’s government incentives, acquisitions, securities purchases, and noncash asset additions are outside the gross cash capex convention used here. FCF is not a standardized GAAP statement subtotal. Read the company’s own reconciliation before comparing its reported FCF with this one.

ROIC is not ranked in this table. A consistent operating-capital comparison would need reviewed excess-cash, investment, lease, R&D, goodwill, tax, and acquisition adjustments. Dividing these reported profits by an unreviewed book denominator would imply more comparability than the figures support.

Reproducibility. Download the source inputs and fact lineage (JSON). Each input carries its filing/release link and, for TTM values, the positive and negative components. Prices come from the six linked historical-price pages. The displayed ratios are calculated from these frozen inputs, not copied from a vendor’s ratio definitions.

06 / A REPEATABLE READING PROCESS

Turn statements
into a business thesis.

Fundamental analysis is an argument about the future, supported by the past. Read several annual reports and recent quarterly updates. Understand what earns the money before choosing a valuation multiple.

  1. 01

    Explain how the company makes a dollar.

    Who pays? For what? Is revenue recurring, cyclical, regulated, or dependent on a few customers? Read segment results and the notes, not just the consolidated headline.

    BUSINESS MODEL
  2. 02

    Trace sales into durable operating profit.

    Compare 3–5 years of sales, gross margins, operating margins, and share counts. Separate volume from price increases, core operations from investment gains, and organic growth from acquisitions. Reconcile adjusted metrics with GAAP.

    INCOME STATEMENT
  3. 03

    Trace profit into cash after reinvestment.

    Inspect receivables, inventories, payables, customer advances, stock compensation, and capex. Distinguish maintenance from expansion spending where disclosure allows. Test whether today’s high FCF is sustainable.

    CASH FLOW
  4. 04

    Ask whether the company can survive a bad year.

    Check available cash, debt maturities, interest, leases, covenants, purchase commitments, and contingent liabilities. Negative FCF needs funding; strong headline cash may have arrived through borrowing or share issuance.

    BALANCE SHEET + NOTES
  5. 05

    Ask what the next dollar of investment will earn.

    Estimate adjusted ROIC and compare it with a justified cost of capital. Track the trend. Growth creates value when the incremental returns justify the reinvestment and risk.

    CAPITAL ALLOCATION
  6. 06

    Ask what the current price assumes.

    Use normalized earnings and cash-flow scenarios with reasonable peer and historical multiples, or a DCF. Convert between enterprise and equity value correctly. Include dilution. Write down which growth, margin, and reinvestment assumptions make the price work.

    VALUATION
  7. 07

    State what would prove the thesis wrong.

    Define observable evidence: shrinking margins, slower collections, weaker incremental returns, funding needs, or customer losses. Keep the valuation range and uncertainties visible instead of turning one ratio into a verdict.

    AN INVESTMENT ARGUMENT

The statements tell you what the business did.
The price asks what you believe it can do next.

Revenue / sales
Revenue records sales earned during the period, subject to recognition rules. It is not the same as cash collected: a sale on credit creates a receivable until the customer pays.
Cost of goods sold
The cost of products actually sold, such as beans, milk, food, and cups used by a coffee shop. Buying inventory initially creates an asset; its cost becomes an income statement expense when that inventory is sold.
Gross profit
Revenue minus cost of goods sold. It shows what remains to cover other operating expenses, interest, and tax. Gross margin is gross profit divided by revenue.
Operating costs
Day-to-day costs such as wages, rent, and marketing generally become expenses as the business consumes those services. This teaching ledger separates cash costs from depreciation; real statements may combine them.
EBITDA
Earnings before interest, taxes, depreciation, and amortization. Removing those charges does not remove the need to pay tax, service debt, replace equipment, or fund working capital. EBITDA is not operating cash flow.
Depreciation
A long-lived asset’s cost is allocated to the periods that use it. The charge reduces this year’s profit and equipment’s book value; it is not a new cash payment. Amortization applies a similar idea to certain intangible assets.
Operating profit / EBIT
Profit from operations before interest and income tax, after operating expenses including depreciation. EBIT literally means earnings before interest and taxes; a filing’s EBIT and operating income can differ if non-operating items are included. This guide uses reported operating income.
Interest versus principal
Interest is the cost of borrowing and is an income statement expense. Repaying the loan principal reduces cash and debt; it does not create a second expense. Under U.S. GAAP, interest paid is generally operating cash flow and principal repayment is financing cash flow.
Pretax profit
Profit after interest and other applicable items, before income tax. In the coffee shop model, operating profit minus interest leaves pretax profit. A company’s non-operating gains can make this subtotal quite different from operating profit.
Income tax
The tax expense associated with accounting profit. Actual cash taxes can differ because tax rules and accounting rules recognize items at different times. The coffee shop assumes a 20% rate on positive pretax profit and pays the tax in cash.
Net income / net profit
The accounting profit after expenses, interest, and tax. It is the starting point for the indirect cash flow reconciliation, not the amount of cash generated or dividends paid. Company comparisons here use consolidated GAAP net income.
Why add depreciation back?
Net income already deducted depreciation, but no cash left for that charge this year. Adding it back removes the noncash deduction when reconciling profit to operating cash. The equipment’s actual purchase appears separately as investing cash outflow.
Accounts receivable
Amounts customers owe for sales already recognized. An increase means some reported sales have not yet become cash, so it is subtracted in the indirect operating cash flow reconciliation. Collection later swaps receivables for cash without recording another sale.
Operating cash flow (OCF)
Cash generated or used by the business’s operating activities. In the indirect method, start with net income, adjust for noncash items, then adjust for timing changes such as receivables, inventory, and payables. It is measured before cash capital expenditure.
Why isn’t capex an income statement expense?
The coffee shop’s equipment upgrade provides benefits over several years. It is capitalized as equipment on the balance sheet, while the cash payment is an investing outflow on the cash flow statement. Its cost reaches the income statement over time through depreciation, rather than as the full purchase price immediately. Routine repairs or purchases that do not qualify for capitalization are expensed instead.
Free cash flow (FCF)
This guide defines FCF as operating cash flow minus gross cash capital expenditure. It is an analytical subtotal, not an extra cash flow to add to the cash statement. Acquisitions, debt repayments, and other uses of cash can still follow, and companies’ own FCF definitions may differ.
Dividends paid
A distribution to owners, not a cost of earning revenue. Under U.S. GAAP it is a financing cash outflow. It reduces cash and retained earnings, without reducing this year’s net income.
Net change in cash
Combine operating, investing, and financing cash flows, plus any applicable exchange-rate effects. The coffee shop’s change is OCF minus capex minus dividends. FCF is already part of that calculation and must not be added a second time.
Cash balance
Cash is a stock of money at one date; cash flow is its movement over a period. Ending cash equals beginning cash plus the net change. Company figures here include cash equivalents, but exclude investment securities and other noncash assets.
Inventory
Goods held for future sale or use in production. Buying them uses cash but initially creates an asset. Their cost enters the income statement as the goods are sold or consumed, or earlier if an accounting write-down is required.
Equipment, net
Equipment’s recorded cost less accumulated depreciation and any applicable impairments. The coffee shop ends with starting equipment plus new capex minus depreciation. Book value is an accounting balance, not necessarily resale value.
Total assets
Recorded resources such as cash, receivables, inventory, and equipment. Assets equal liabilities plus equity. Internally developed brands and some other valuable resources are not fully recognized, so recorded assets are not the whole market value of a business.
Debt
Borrowed money owed to lenders. Borrowing adds cash and a liability; it is not sales or profit. The debt number used for EV here is disclosed funded borrowing, rather than every liability, with each company’s convention explained in the methodology.
Contributed capital
Owners’ investment recorded in equity. Issuing shares raises financing cash and equity, not revenue. Its recorded amount is different from what investors later pay each other for shares in the stock market.
Retained earnings
Accumulated accounting profits kept in the company after distributions and applicable adjustments. The coffee shop retains net profit minus dividends. Retained earnings is an equity account, not a separate pile of cash.
Book equity
The accounting residual: recorded assets minus liabilities. In the coffee shop it equals original contributed capital plus retained earnings. Market capitalization prices investors’ ownership claims; it can be much higher or lower than book equity.
Accrual accounting
Record revenue when earned and expenses when incurred under the applicable rules, rather than simply when money changes hands. This makes profit useful for measuring a period’s activity, but also creates timing differences that the cash flow statement reconciles.
Operating working capital
Short-term operating resources minus operating liabilities, such as receivables and inventory less supplier payables. Growth can tie up cash before customers pay. For ROIC and cash flow analysis, distinguish operating working capital from a broad current-assets-minus-current-liabilities measure.
Stock-based compensation
Compensation paid through equity awards generally reduces reported profit, even though it may not use cash at that time. Adding the noncash expense back to operating cash flow does not erase its economic cost: issued shares can dilute existing owners.
Market capitalization / equity value
Share price multiplied by shares outstanding: the market’s price for shareholders’ claims. A share price by itself cannot compare company size or cheapness. These estimates use lagged filed share counts and value all common classes at the quoted class’s price.
Enterprise value (EV)
A value for the operating business across capital providers. This guide’s simplified bridge is market cap + funded debt − cash and cash equivalents. A fuller calculation may adjust for preferred shares, minority interests, leases, excess cash, and other non-operating assets.
Price / sales (P/S)
Equity value divided by annual revenue. Revenue multiplied by P/S reconstructs equity value, not enterprise value. On a consistent per-share basis, revenue per share multiplied by P/S reconstructs the share price. Sales alone do not tell you margins, reinvestment needs, or fair value.
Other items and tax, net
This guide derives the combined bridge from operating income to net income as net income minus operating income. It includes the net effect of non-operating gains/losses, interest, taxes, and applicable allocations. It is not a separate reported operating-profit line.
Cash reconciliation, net
This guide derives the combined bridge from accounting profit to operating cash as OCF minus net income. Noncash charges, gains removed from operations, working-capital timing, and other operating adjustments enter it. It must not be interpreted as depreciation alone.
Liabilities
All recorded obligations, including borrowing, supplier payables, accrued costs, taxes, and deferred revenue. Funded debt is only a subset. The selected balance sheet derives other liabilities by subtracting the displayed debt from total liabilities.
Noncontrolling interests
An ownership claim in consolidated subsidiaries held by other owners. Consolidated assets minus liabilities need not equal the parent shareholders’ equity alone. A fuller EV analysis treats these claims consistently with the consolidated operating earnings.
Price / earnings
The usual P/E is price per share divided by diluted earnings per share. This table instead uses estimated market cap divided by consolidated net income, labeled a proxy. Temporary gains or peak-cycle profits can make a multiple look deceptively low; losses make the usual positive multiple unhelpful.
Price / free cash flow
Estimated equity value divided by this guide’s OCF-minus-capex measure. It asks what equity investors pay per dollar of annual cash remaining after gross capital spending. FCF can fluctuate with investment cycles and working capital, and is not necessarily paid to owners.
Free cash flow yield
Annual FCF divided by equity value, expressed as a percentage. Positive P/FCF and FCF yield are reciprocals: 20× corresponds to 5%. This is neither a promised dividend yield nor a forecast of the stock’s return; a negative value means this FCF measure consumed cash.
EV / operating earnings
Compare a value including lenders’ claims with earnings measured before interest. EV/EBIT retains depreciation; EV/EBITDA removes it. Consistent treatment of leases, non-operating items, and capital requirements matters when comparing businesses.
EV / sales
Enterprise value divided by annual revenue. It remains calculable when earnings are negative, but says little about how much revenue can become profit or cash. Similar sales multiples can represent very different values if margins and reinvestment needs differ.
Price / book
Estimated market cap divided by accounting equity. Buybacks can shrink book equity, while internally developed brands and expensed research can leave important assets unrecorded. A high or low ratio alone does not establish fair value.
Leverage and interest coverage
Debt/EBITDA compares borrowing with an operating earnings measure; it is not literal years to repay because EBITDA has not paid tax or capex. EBIT/interest expense measures the cushion for interest. Also inspect maturities, covenants, cash, and downturn earnings.
Net operating profit after tax (NOPAT)
Operating profit after an assumed normalized operating tax charge, before interest. It measures profit available to both lenders and shareholders, which matches ROIC’s debt-plus-equity capital base. It is different from after-interest net income.
Operating invested capital
Capital committed to the operating business. A starting point is book equity + interest-bearing debt − excess cash and non-operating assets, with consistent accounting adjustments. Using average beginning and ending capital matches a year’s profit to capital employed over that year.
Return on invested capital (ROIC)
NOPAT divided by average operating invested capital. It measures the business’s return on the capital it uses, not the shareholder’s return at today’s stock price. Returns on new investment can differ from the historical average.
Weighted average cost of capital (WACC)
The weighted required returns of equity and debt capital providers, with a consistent after-tax debt cost. It is an estimated opportunity cost, not an income statement expense. ROIC above WACC suggests value creation if the measurements and assumptions are sound.
Discounted cash flow (DCF)
Estimate future cash flows and convert them to present value using a discount rate consistent with their risk and capital providers. Firm cash flows use a firm discount rate; equity cash flows use an equity rate. Growth, reinvestment, and continuing-value assumptions can dominate the result.
Free cash flow to the firm (FCFF)
Cash available to all capital providers before financing flows. A common model is NOPAT + noncash operating charges − capex − additional operating working capital. Unlike this guide’s simple OCF-minus-capex figure, FCFF must handle interest and taxes consistently with enterprise valuation.
Trailing twelve months (TTM)
The latest reported year of activity, which may end months before the stock-price date. For interim filings this guide computes annual + current year-to-date − prior year-to-date. Balance sheet figures remain a snapshot at period end, rather than a twelve-month sum.
