Why Small Caps Are Beating Large Caps in 2026
A short read on the VB vs. VV performance gap, and what the valuation discount is really worth
Through the close on August 14, 2026, the Vanguard Small-Cap ETF (VB) has returned 19.9% year-to-date on a price basis against 13.6% for the Vanguard Large-Cap ETF (VV), a gap of 6.3 percentage points. If it holds through December, it ends five consecutive years of large-cap leadership. The Russell 2000 is on pace for its best year since 2003 after its strongest first half since 1991. Three things explain most of it.
1. The mega-cap engine idled
The story of 2026 is less that small caps ran than that the largest companies stopped. The Magnificent 7 have advanced roughly 4% year-to-date while the S&P 500 gained about 11%, and they stopped moving as one trade: State Street reports average pairwise correlation collapsing to 0.27 from 0.78, with Apple up 14.8% while Microsoft fell 21.4%. That matters mechanically, because VV's top ten holdings are about 36.6% of assets. When a third of the fund goes sideways, the rest must work extraordinarily hard. VB, with roughly 1,300 holdings and no position above 30 basis points, has the opposite profile.
2. The AI trade moved downstream, not away
Investors did not abandon artificial intelligence; they bought the suppliers instead of the spenders. Data-center, networking, cooling and specialized-software suppliers sit mostly in the small- and mid-cap universe. Three of VB's largest positions are Flex, Astera Labs, and Ciena. The spending is real: the Magnificent 7 guided to roughly $680 billion of capital expenditure for 2026. But one statistic should give pause. Unprofitable Russell 2000 constituents rose 154% since mid-2025 against 34% for profitable ones, the signature of a narrative re-rating, not an earnings-driven advance.
3. Cheaper, more domestic, better financed
Small caps typically derive 70% to 80% of revenue domestically, which insulated them from tariff friction. Roughly 40% of Russell 2000 debt floats, so the three cuts delivered through late 2025 are still flowing into interest expense, though note the Fed has since held for five consecutive meetings, with three July dissents favoring a hike. Tax changes moving the interest deduction limit from 30% of EBIT to 30% of EBITDA favor leveraged, capital-intensive businesses over debt-free platforms. And roughly $170 billion of pharmaceutical patent expirations is pushing large-cap biotech to buy small-cap pipelines.

Two observations. First, the discount is real but no longer extreme. VB trades 15% to 20% cheaper than VV on trailing earnings, meaningfully narrower than the index-level comparison strategists quote, the Russell 2000 near 16x forward against the S&P 500 at 23x, described as a thirty-year extreme earlier this year. VB's Morningstar benchmark screens out the deepest-loss microcaps that distort Russell aggregates, so it is the cleaner but less dramatic comparison. A 20x multiple is cheap relative to a large-cap index carrying an unusual concentration premium, not cheap in absolute terms.
Second, VB now out-yields VV, at 1.17% against 1.01%. This is not small-cap generosity but large-cap price appreciation and the low payout ratios of mega-cap technology. Neither fund is an income vehicle, and the 16-basis-point gap should not drive an allocation.
What could break the trade
The rally is narrow. Bank of America notes Russell 2000 performance has been concentrated this year. Owning the index is not owning small-cap breadth.
The rate tailwind is spent. With the Fed on hold and hawkish dissents on the record, the financing-cost case depends on cuts that may not arrive.
Beta cuts both ways. Schwab calculates the average S&P 500 member has drawn down 21% at some point this year, and the unprofitable cohort now leading small caps is the first to unwind when risk appetite turns.
Our read
We think 2026 is better understood as a large-cap pause with a high-beta risk trade layered on top than as a durable transfer of leadership. A pause in mega-cap earnings momentum is cyclical and can reverse on one quarter of hyperscaler results. A genuine small-cap earnings cycle, the thing that would justify a structural overweight, requires the downstream AI beneficiaries to convert order books into profits, and requires the unprofitable half of the index to stop leading. The valuation gap is a supportive backdrop, not a thesis: it was equally wide in each of the last four years and paid nothing in any of them.
