Stock Funds Are Up 10% This Year, Here's What That Means

Stock funds were up 10.3% for 2026 through September, according to third-quarter 2026 coverage published Oct. 4 by The Wall Street Journal. The figure is a year-to-date return through Sept. 30, or gain from Jan. 1 onward. It sets the average to beat in the final quarter.

The Oct. 4 report is the latest Journal fund update for 2026. It replaces earlier summer snapshots for year-to-date comparison. Those older numbers are now history, not current totals.

In coverage published Aug. 9, the Journal reported international-stock funds were up 0.6% on average for the month, for a year-to-date gain of 11.1%, according to The Wall Street Journal. That reading came almost two months before the end-September cutoff. The different dates block direct comparison.

The Journal published two related stories during the interval. Its Intelligent Investor column titled “Leverage or Luck?” was published Sept. 15, according to The Wall Street Journal. A separate article titled “How Index Funds Went From Being Mocked to Feared” was published Aug. 21, according to The Wall Street Journal.

The broader context here is the September starting point. A gain above 10% after nine months narrows the math for the full year. Yet small gaps in the fourth quarter can still reshuffle quartile rankings, or who lands on top or bottom. Limits on straying from a benchmark, what pros call tracking-error budgets, plus peer hurdles and fee drag are now judged on nine months, not a fresh start.

Looking at what this means for attribution, an average hides more than it shows. Like a class test average, it mixes the broad market rise with company size and style, business sectors, currency shifts for foreign stocks, idle cash and fees. Spreads between funds will tell the story. Without a look inside holdings, you cannot separate steady results from good timing, or skill from just riding the market.

In my view, the numbers with the two stories raise questions, not answers. Leverage-versus-luck asks how much risk sat behind extra return. Indexing-versus-active asks which yardstick to use. Neither is settled by 10.3% or an 11.1% August reading for international funds. Both need peer groups with closed funds, fair benchmarks and many periods.

Looking at what this means for the fourth quarter, choices are tight. Managers who must stay close to a benchmark gain little by straying far. Those behind must decide how much risk to take. Those ahead must decide how much to protect. None of that shows in the average. It only sets the hurdle.
