The first half’s weird and wild weather

So far, 2025 has given us nearly every kind of investment weather, from the cold and rainy—that is, volatile and bearish—first quarter to the placid and pleasant days that constituted most of the second. To be sure, we suspect that many investors feel like at least a year’s worth of weather was somehow crammed into the first seven months of the year. We think it’s notable that the first half of 2025—which could be described as “A Tale of Two Quarters”—saw few (if any) of the elements that drove stock prices down in the first quarter removed or resolved in the second quarter. In other words, investors still face a long list of uncertainties and challenges, including ongoing war and violence in the Ukraine and Gaza, rapid shifts in tariff rates and implementation, stubborn (and possibly increasing) inflation, and an overall anxiety about the state of the economy, whether thinking globally or locally.

Unfortunately for small-cap investors and dedicated asset class devotees like us, however, the combination of 2Q25’s welcome rebound and concurrent lower volatility did not shift market leadership. In part because of the first quarter’s steep declines, which hit small-caps harder than their bigger siblings, year-to-date results for the period ended 6/30/25 were not positive across the board. Small- and micro-cap stocks remained underwater through the end of June, with the Russell 2000 falling -1.8% while the Russell Microcap lost -1.1%. The large-cap Russell 1000 Index, however, gained 6.1%, and the Russell Top 50 Index rose 5.2% for the year-to-date period ended 6/30/25. July was a positive month for small- and large-caps alike, though it was not strong enough to pull the small- and micro-cap indexes into the black on a year-to-date basis. As frustrating as the last several years have been for small-cap investors, the long cycle of mega- and large-cap leadership kept its streak alive through the end of July. We delve into why this leadership cycle can shift below.

What’s working in US small-cap

As volatility began to ebb following the small-cap bottom on 4/8/25, the Russell 2000 advanced 24.0% through the end of June. And although both small-cap style indexes had impressive, double-digit returns, small-cap growth led during the upswing, with the Russell 2000 Growth Index climbing 27.7% while the Russell 2000 Value Index rose 20.2%. In addition to growth doing better than value within small-cap, the highest returns in both the second quarter and off the small-cap low on 4/8/25 came from stocks with no dividends, no earnings, and low or no ROIC (returns on invested capital—a profitability and capital allocation metric we use to gauge quality).

This kind of high-growth, low-quality rally is consistent with previous small-cap rebounds following corrections. (And small-caps experienced a genuine bear market—that is, a decline of 20% or more from a previous peak—from the Russell 2000’s peak on 11/25/24 through 4/8/25, when the index fell 27.5%.) If the past is prologue, however, higher quality small-cap stocks, as well as those with dividends, should begin to outpace those of lower quality, assuming that the current rally continues—the last week of July notwithstanding.

We broke down the Russell 2000 into quintiles of return on equity (ROE), another quality metric that measures a company’s financial performance. It’s calculated by dividing net income by shareholders’ equity. Higher ROE generally means that a company’s management has allocated capital effectively. As the chart shows, higher ROE small-caps begin to outperform the longer a bullish run was extended, perhaps the result of investors seeking more profitable companies once they felt greater confidence in the upswing’s longevity.

Some of the highest returns for the first six months of 2025 came from non-US equities and were especially good for small-caps. The MSCI ACWI ex-USA Small Cap Index rose 17.7% for the first half of 2025 while its large-cap counterpart was up 17.1%. Year-to-date through the end of July, small-caps built their advantage—the MSCI ACWI ex-USA Small Cap Index advanced 17.9% while its large-cap counterpart gained 16.8% for the same period. So, while many investors have taken flight away from US issuers amid concerns about our economy and near-term corporate profit prospects, we think it should be noted that the US economy has, like the capital markets, shown remarkable resilience during some highly challenging days so far in 2025. Moreover, non-US stocks have just begun to reverse a long period of underperformance versus domestic equities, which gave many international companies attractively low valuations at the end of 2024.

Volatility is an ally

Between the beginning of 2025 and the end of July, an interesting dynamic was at work, which we might characterize as the rise and fall of volatility. Stocks were highly volatile in both the run up to and immediate aftermath of “Liberation Day” on April 2, with most share prices cratering before beginning to recover more steadily in May. There was heightened volatility not just from the VIX—the CBOE S&P 500 Volatility Index, often referred to as the “fear gauge”—but also when tracking the number of trading days when the small-cap Russell 2000 Index moved up or down at least 1%. During April of 2025, 62% of trading days (13 out of 21) had such moves; in May there were only 33.3% of days (7 out of 21). The average for the first six months of 2025 was 46%—while going back to 2000, the annual average was 42% of trading days. So far this year, then, small-caps have shown either higher-than-usual volatility or were comparatively calm. In essence, the story of the first half was that stocks of all sizes were volatile—until they weren’t.

Yet regardless of market cap, style, or geography, we expect stock prices to remain volatile for the rest of the year, if for no other reason than that the market hates few things more than uncertainty—and “uncertainty” certainly appears to be the watchword for the next several months. For all the pro-growth policies and relaxed regulations that are being proposed or have already been implemented, US President Trump’s second term has already created a lot of economic anxiety, most of it centered on tariffs. Going back to November, we knew that there would be Republicans in control of both Houses of Congress and the White House—which signaled stability to the capital markets. This has nothing to do with ideology; it is about giving investors a reasonably good idea of what the policy backdrop will look like going forward.

Many investors felt confident that any tariffs would be used as a negotiating tactic. But they have so far ended up being higher and deployed much more capriciously than anyone was expecting. This kind of uncertainty typically wreaks havoc on stock prices. At the same time, the impressive recovery for US stocks suggests that investors have learned to expect the unexpected from the Trump Administration—which has so far also been a boon to valuation-conscious investors like us who see volatility as an opportunity. Our investment teams have been working diligently to take advantage of short-term moves in order to build positive long-term performance.

Certainly uncertain

So, while we welcome volatility in the short run, we also acknowledge that attempting to chart a course for small-cap stocks, or any other asset, is even more challenging than usual. Recent gross domestic product (GDP) growth offers a useful example. The first quarter showed the US economy contracting at an annualized rate of -0.5% while the second quarter number was 3%. This disjunct can be explained in part by slower consumer spending throughout the first half of 2025 as well as by the fevered pace of pre-tariff inventory stockpiling in the first quarter that was followed by a precipitous drop in imports in the second quarter. The upshot was a first-half average of 1.25% annualized GDP growth, a full percentage point lower than the pace set in 2024. The downward trend in consumer spending (to say nothing of the decline in consumer confidence) is especially worrisome since that spending accounts for two-thirds of GDP. The 1.4% advance in consumer spending for 2Q25 was an improvement from the underwhelming 0.5% figure that kicked off 2025—but it was also most subdued pace in consecutive quarters since the pandemic. Adding to the uncertainty about the days ahead was the slower pace of business investment in the second quarter.

Then there was the mixed bag of economic data that the Federal Reserve then (Fed) outlined when announcing in late July that interest rates would hold steady until at least September. In its statement on July 30, the Fed said, “Although swings in net exports continue to affect the data, recent indicators suggest that growth of economic activity moderated in the first half of the year. The unemployment rate remains low, and labor market conditions remain solid. Inflation remains somewhat elevated.” In other words, we have no clear direction for where the economy is headed. (It’s also worth noting that two of the three remaining Federal Open Market Committee (FOMC) meetings—September’s and December’s—will also have the central bank’s Summary of Economic Projections.)

At the risk of understatement, much remains unsettled around tariffs. Preliminary arrangements have been worked out with Japan, the European Union, and other nations, though the possibility of higher tariffs persists (as of this writing) for China and Mexico—two of the United State’s most important trading partners. On July 31, Trump unveiled sweeping tariffs on several countries, including a hefty (and unreasonable in our view) 35% tariff on Canadian imports while he threatened India with 25% tariffs for purchasing energy and weapons from Russia. There were also contradictory reports around what would and would not be subject to tariffs on imports from the EU in addition to unresolved questions around that region’s purchases of US energy, steel, and aluminum. Needless to say, uncertainty sums up much that is happening on the economic policy front so far this year. Yet resilience has been equally important. For us as active small-cap specialists, the first half’s most welcome news has been the generally positive slate of earnings across the market so far.

Four charts outline an optimistic US small-cap forecast

Most importantly, we remain confident about the long-term prospects for our chosen asset class. When looking ahead, there’s always far more that we don’t know than we do. Even the best-informed and data-driven observations involve some guesswork. We always think that history offers a useful guide, while also being mindful that each historical period comes with its own context; similar conditions may yield markedly different results. And as we’ve detailed, our current situation has more than its share of sizable unknowns. Along with the ultimate arrangement and implementation of tariffs, we have an increasingly divided electorate and the prospect of shifting congressional control in 2026. The state of geopolitics remains fraught with dangers and risks.

Yet there are also bright spots: The effects of reshoring, reindustrializing, and infrastructure improvements have not yet reached their respective ends. As we mentioned above, both the capital markets and economy proved remarkably resilient throughout the challenging first half of 2025.

Against this backdrop, there is also what we do know—and small-cap stocks are what we know best. At the end of June, the Russell 2000 remained much less expensive than the Russell 1000. Based on our preferred index valuation metric, EV/EBIT or enterprise value over earnings before interest and taxes, small-caps stayed close to a 25-year low relative to large-cap stocks.

We think that small-cap stocks much more attractive valuations become even more compelling when combined with the promising earnings outlook vis-à-vis large-caps, as seen in the two charts below.

Moreover, many small-caps stocks are just starting to emerge from a two-year earnings recession, which, we believe, should help boost performance for an asset class that’s lagged large-cap for several years and currently faces low expectations. And previous low expectations and relatively underwhelming returns have often been opportune times to increase allocations. Historically, we have found that sitting on the sidelines during corrections or the early stage of rallies has carried a high cost. We therefore welcome a market environment, however challenging (and even confusing at times thanks to the chaos around tariffs).
