Active vs Passive Investing: Did Your Fund Beat the Benchmark?
Your fund gained 8%. You made money. But if a suitable benchmark gained 10% over the same period, that positive return leaves another question unanswered: what did the fund deliver relative to the alternative?
Your practical takeaway: Compare the exact share class against an appropriate benchmark over matching dates, currency and return basis, then inspect the costs before judging performance.

The new scorecard, and the category that changes the story
S&P Dow Jones Indices published its SPIVA U.S. Mid-Year 2026 scorecard on September 17, 2026. It reports that 67% of active U.S. large-cap equity funds underperformed the S&P 500 in the first six months of 2026. In a different category, 49% of U.S.-domiciled international funds underperformed their respective benchmark (page 3 of the report). The categories do not tell the same story. Read the SPIVA scorecard.
The report also compares the large-cap figure with 79% over the full year 2025. Those windows differ: six months and twelve months. Treating that comparison as a clean estimate of a lasting improvement would ask the figures to do more than they can.
This is a count of funds, not a share of investor dollars; SPIVA includes funds that did not survive the period. SPIVA is produced by an index provider. It is useful category-level evidence to inspect, not a promise about the next period, a personal allocation, or proof that a particular fund will lose money.
First define the two jobs
An active strategy makes investment choices intended to meet its objective, which may include beating a benchmark. A passive index strategy aims to follow an index. Tracking an index still involves costs and implementation, so owning an index product does not mean receiving the index’s published return exactly. Nor does an index label tell you whether its market exposure suits your purpose. SEC: fund strategies and characteristics.
Start with the fund’s stated objective and benchmark. Comparing an international equity fund with a U.S. large-cap index may mostly reveal different market exposure. It does not isolate the manager’s contribution. A low-volatility or income mandate also needs to be judged against its actual job, rather than whichever headline index had the best year.
Work the gap in money, not adjectives
Hypothetical comparison: both start with $10,000, have no added or withdrawn cash, use the same currency and dates, and reinvest distributions. The fund’s return after its fund expenses is 8%; the suitable benchmark’s total return is 10%.
| Fund | Benchmark | |
|---|---|---|
| Starting amount | $10,000 | $10,000 |
| Return | 8% | 10% |
| Ending value | $10,800 | $11,000 |
The gap is 2 percentage points, or $200 on this starting amount. The investor earned $800; the comparison still shows underperformance. A benchmark is not directly investable, and an actual tracking fund would have its own costs, so this is a diagnostic comparison rather than a guaranteed alternative outcome.
Four fields to copy before comparing
Open the factsheet and prospectus for your exact share class. Write down its objective and benchmark, the start and end dates, the currency, and whether the figures are total returns with distributions reinvested. Also note whether each return is before or after fund expenses, and whether it excludes your account charges or tax.
If those fields do not match, pause the calculation. A cumulative three-year return cannot be compared directly with an annualized three-year rate. A price-only index cannot be compared fairly with a fund return including distributions. Where your own deposits and withdrawals change the experience, distinguish the fund’s reported performance from the return on your personal cash flows.
The fee that never appears as a separate bill
The SEC’s July 23, 2025 investor bulletin explains that ongoing fees reduce the money left earning returns. Fund operating expenses are usually deducted from fund assets and appear as an expense ratio in the prospectus. SEC investor bulletin on fees.
For a simple hypothetical illustration, assume a $10,000 investment, constant 6% annual gross growth, no cash flows or taxes, and annual fee drag approximated by subtracting the fee rate. A 0.2% annual fee leaves 5.8%; a 1% fee leaves 5%. After 20 years, $10,000 × 1.058²⁰ is about $30,883; $10,000 × 1.05²⁰ is about $26,533. The difference is about $4,350. This simplified calculation isolates fee drag. It does not forecast a fund’s returns or reproduce its daily fee accounting.
Do not subtract the expense ratio again from a return already stated after those expenses. Instead, check for other charges. The SEC notes that a prospectus fee table may omit costs such as brokerage commissions and intermediary fees. SEC guide to fund fees and expenses.
A better question than “which one always wins?”
Write one sentence about the comparison: “This share class returned ___ against ___ over ___, on ___ basis, with ___ additional costs.” That makes a conversation with an adviser or a further investigation specific. A short period cannot establish durable skill, and a category statistic cannot select your next investment.
Use the latest scorecard as a reason to examine the benchmark and costs. Then connect the result to your intended timeframe and risk exposure using the investing-versus-trading guide and diversification guide.
