BofA: 44% of large-cap active funds underperform as megacaps dominate

Summary

In September, only 44% of large-cap active funds managed to outperform their benchmarks, as highlighted by BofA, due to a market environment increasingly dominated by a few megacap stocks. Specifically, the cap-weighted S&P 500 outperformed its equal-weight counterpart by nearly 5 percentage points, underscoring the trend of narrowing market leadership primarily among large technology and semiconductor firms. This has posed significant challenges for active fund managers, particularly in the growth segment, where a small number of stocks, notably Meta and AMD, drove 70% of the gains in the Russell 1000 Growth index.

Analysis

AMD: Advanced Micro Devices designs high-performance semiconductors, CPUs, GPUs, and data-center accelerators used across consumer, enterprise, and AI workloads. It competes directly with other leading chipmakers and has established itself as a core megacap technology holding. According to the cited analysis, AMD contributed substantially to the same narrow leadership that weighed on growth-oriented active managers. BofA: Bank of America is a leading global financial services company that offers investment banking, wealth management, and equity research to institutional and retail clients. BofA regularly issues monthly and quarterly market commentary analyzing fund flows, sector performance, and benchmark comparisons. Its September analysis directly attributes active large-cap managers' underperformance to the outsized gains concentrated in a handful of megacap names. Meta: Meta Platforms operates the world's largest social media ecosystem, including Facebook, Instagram, and WhatsApp, while generating the majority of its revenue from digital advertising. It remains one of the most prominent megacap growth companies in the U.S. equity market. The BofA report singles out Meta as one of two stocks responsible for the bulk of the Russell 1000 Growth index's monthly advance. S&P 500: The S&P 500 is a widely followed equity benchmark comprising 500 large-capitalization U.S. companies selected for market size, liquidity, and industry representation. It is maintained by S&P Dow Jones Indices and serves as the primary reference for U.S. large-cap performance. The news highlights that the cap-weighted version of the index materially outpaced its equal-weighted counterpart during September. Growth Segment: Within growth benchmarks, performance has been especially concentrated, with a small number of names accounting for the majority of index-level returns. Market Breadth: Equity market gains in recent weeks have been driven by a shrinking number of large technology and semiconductor names rather than broad participation across sectors. Active vs Passive: Active large-cap strategies have continued to face headwinds when market returns are dominated by a limited set of high-momentum megacaps.
