The Hurdle: SPY vs. Day Trading

Buy-and-hold pays tax once, at the end, at the long-term rate. A day trader pays the higher short-term rate on every year’s gains, plus trading costs. That gap compounds into a hurdle of roughly 5 percentage points a year before trading skill even enters the picture.

Base case throughout: $100,000, calendar years 2006–2025, federal tax only, 15% long-term for SPY, 32% short-term for the trader, and 1% a year trading drag. All figures are model outputs from historical SPY returns, not forecasts.

1. Same $100k, same 20 years

SPY rides the market up and down and sells once. The trader’s path is the smooth constant return that just matches SPY’s after-tax ending value. Hover the chart for year-by-year values.

Growth of $100,000 (2006–2025)

The ending balance sheet

SPY before investor tax$793,906
Yearly dividend tax, plus the growth it forfeited−$42,678
Tax on the one final sale−$85,930
SPY after tax$665,298

The punchline: a trader who earned SPY’s own 10.9% gross, but paid 32% on each year’s gains and 1% in costs, would finish with about $364,000. That is 45% less money for the same raw skill.

2. Where the 4.9 points come from

Start from SPY’s after-tax return. Add what the trader loses each year, and you arrive at the gross return the trader must actually earn.

Inside the trader’s account: grow all year, then pay the tax bill

The trader earns 15.8% gross, loses 1% to costs, and pays 32% of each year’s gain in December. That adds up to $266,023 of tax over 20 years. Each payment also stops compounding, so the account ends at $665,298, which matches SPY after tax. The dashed line is the same trades with no yearly tax. It ends near $1.53 million, so the tax cost the trader about $866,000: $266,023 paid plus the growth that money never earned. Zoom into the first 3 years to see the two curves match exactly until the first December. Hover any drop to see that year’s tax.

Building the required return (% per year)

Two reasons tax hurts the trader more

  1. Higher rate. 32% instead of 15% on every dollar of gain.
  2. Earlier payment. Tax cash leaves the account every year, so it never compounds. SPY’s unrealized gains keep working for 20 years as an interest-free loan from the IRS.

Note that SPY’s 10.9% gross sits between its 9.9% after-tax return and the trader’s 15.8%. The headline hurdle is measured from the gross number.

3. The hurdle under other years and tax brackets

The hurdle grows with the tax bracket and with how good the market was. In flat or falling markets there are no gains to tax, so it nearly vanishes.

Simple average of the yearly returns: 12.3%. Compound annual growth: 10.7%. Volatility is why the average overstates what you actually earn.

4. Tax rules worth knowing

LONG-TERM (held > 1 yr)

0 / 15 / 20%

15% band runs to $545,500 single and $613,700 joint taxable income in 2026. Most investors pay 15% or less.

SHORT-TERM

10–37%

Taxed as ordinary income at the same brackets as wages. Day-trading gains are almost all short-term.

NIIT

+3.8%

Extra layer on investment income above $200k single / $250k joint modified AGI. Applies to both paths.

NOT PER TRADE

Annual

Gains and losses net on the yearly return. Many traders also owe quarterly estimated payments. What is §475(f)?

5. How often do professionals clear it?

Rarely, and that is before the trader’s tax hurdle. Fund returns below are after fund fees but before investor tax.

7. Method, limits, and sources

SPY path. Calendar-year total returns, 1994–2025, dividends reinvested. Total return minus price return approximates the dividend, taxed yearly at the long-term rate; the remaining gain is taxed once at the end. Capital-loss benefits are not credited.

Trader path. A constant yearly gross return, minus trading drag, minus tax on any positive gain each year. Loss carryforwards, wash sales, §475(f), leverage, and the extra drag from volatile returns are not modeled, so the real hurdle is likely higher.

Not counted. Screen time, labor, drawdowns, leverage risk, and strategy capacity. Matching the ending balance is not matching the life.
