Emerging markets stocks are experiencing a powerful bull run, delivering an impressive 39% return over the 12-month period through August. For everyday investors and institutional players alike, this surge highlights a broader revitalization across developing economies. Yet, despite this robust upward momentum, one prominent portfolio has found itself trailing behind the broader market barometer: the Baron Emerging Markets fund (BEXFX), a trusted name that holds a coveted spot among the Kiplinger 25 group of elite, no-load mutual funds.

While the fund’s 24% gain over the same 12-month timeframe is undeniably strong on a standalone basis, it noticeably lags behind the MSCI Emerging Markets Index. This performance gap marks a distinct reversal of fortune for the fund, which only a few months prior was keeping a much tighter and more competitive pace with its primary benchmark. To understand why this divergence has occurred, financial analysts and portfolio watchers are pointing toward a combination of sector-specific pullbacks, shifting momentum in global technology leadership, and the cyclical nature of emerging market equity allocations.

Tech Hits a Rough Patch

A significant driver of the fund’s recent underperformance can be traced directly to the technology sector. Some of the fund’s largest and most conviction-driven holdings in technology were explosive winners throughout 2025 and the early months of 2026. These stellar performers served as the primary engines behind the fund’s robust earlier returns, propelling cumulative gains higher. However, in more recent months, these exact same market darlings have hit a rough patch, experiencing sharp pullbacks that have weighed heavily on the portfolio’s aggregate performance.

The concentration in key semiconductor and hardware giants has proven to be a double-edged sword. Shares in Taiwan Semiconductor Manufacturing Company (TSM), which accounted for a substantial 16% of the portfolio’s assets at the last comprehensive report, have slipped 13% over the past two months alone. At the same time, major South Korean technology giants have faced even steeper corrections. Samsung Electronics, representing roughly 8% of the fund’s assets, has watched its shares slide by 28% over the same recent stretch, while rival memory chip maker SK hynix has dropped 12%.

Compounding these regional pressures, major Chinese internet and technology firms held within the portfolio—including powerhouse names like Alibaba Group Holding (BABA) and Tencent Holdings—have likewise acted as a drag on performance since the start of 2026. Because these technology names form the backbone of both the broader index and active growth-oriented portfolios, any synchronized correction across Asian tech hubs inevitably creates a substantial hurdle for active managers striving to beat the benchmark.

Despite these recent headwinds, fund leadership remains steadfast in its long-term vision and philosophy. In a comprehensive shareholder report covering the quarter that ended in June, manager Michael Kass expressed that he remained quite encouraged by the strong absolute performance of the fund over broader operational windows. Looking at the cumulative picture, the fund has generated a robust 50% gain since the start of 2025. While that figure is undeniably impressive by historical standards, it still trails the MSCI Emerging Markets Index, which boasts a 66% return over the identical multi-year period.

Market observers note that such dispersion is a frequent characteristic of actively managed emerging markets strategies. When momentum clusters tightly around a narrow band of surging index heavyweights—particularly during aggressive benchmark rallies driven by macro liquidity or sudden sector rotations—active stock pickers who maintain disciplined valuations or sector weightings can occasionally find themselves temporarily falling behind.

When evaluated over longer historical horizons, however, the Baron Emerging Markets fund compares much more favorably to its passive benchmarks and peer group averages. Over a 15-year annualized timeframe, the fund has delivered a steady 6.3% return. That long-term performance ranks comfortably among the top 31% of all diversified emerging-markets stock funds tracked by industry analysts. Furthermore, over this extended duration, the fund manages to edge out the MSCI Emerging Markets Index, which posts a 6.0% annualized return over the same long-haul period, demonstrating the enduring value of its deliberate, research-driven investment process through multiple market cycles.
