Baron WealthBuilder Fund: Latest Insights and Commentary

U.S. equities were broadly higher in the third quarter, building on gains from the prior quarter. The S&P 500 Index and NASDAQ Composite set new record highs, most recently on September 22, and the Dow Jones Industrial Average ended the quarter at an all-time high. Small caps led the market recovery, with the Russell 2000 Index finally surpassing its previous record high achieved almost four years ago on November 8, 2021. Market volatility remained muted during the quarter as the CBOE Volatility Index (VIX) continued to trade in the mid-teens, well below its long-term average of around 20. 

The preeminent driver of market strength was the increased likelihood of Federal Reserve (Fed) rate cuts, prompted by signs of weakness in the labor market and the subsequent emergence of more dovish Fed commentary. Rate cut expectations rose in early August following a much weaker-than-expected July nonfarm payrolls report and significant downward revisions to prior numbers. Dovish Fedspeak intensified as the month wore on, with Chair Powell hinting a possible interest rate cut while delivering remarks at the Fed’s annual Jackson Hole conference. Similarly, Governor Waller continued to advocate for cuts while speaking at the Economic Club of Miami. The Fed eventually resumed its rate-cutting cycle at the September meeting, lowering its policy rate by 25 basis points to a range of 4% to 4.25%, after being on hold since its previous cut last December. Robust corporate earnings, narrowing trade uncertainties, a resilient consumer, increased M&A and IPO activity, and sustained AI optimism also contributed to market gains during the quarter. 

The Magnificent Seven complex dominated market returns for a second consecutive quarter, accounting for nearly two-thirds of the S&P 500 Index’s third-quarter gains. The group appreciated 15.5% in the period, outperforming all other securities in the Index, which were up 4.6%, by a double-digit margin. Tesla (+40.0%), Alphabet (+38.1%), Apple (+24.2%), and NVIDIA (+18.1%) posted the largest gains. Meta and Amazon were essentially flat in the period, trailing the broader Index. 

Most sectors closed higher in the period, with Information Technology, Communication Services, and Consumer Discretionary being the only sectors to outperform the broader market thanks to the heavy influence of the Magnificent Seven. Consumer Staples was the only sector to decline in the period, driven by broad-based weakness across a range of sub-industries, including distillers & vintners, personal care products, food retail, tobacco, and household products. Other laggards were Real Estate, Financials, Health Care, Industrials, Energy, and Materials. From a style perspective, small caps outperformed in the third quarter, rising more than 12% and narrowing the gap with mid- and large-cap stocks this year. Performance was mixed between growth and value, with growth stocks dominating in July, losing out to value in August, and rebounding in September. Despite recent volatility, growth generally remains ahead of value year to date, with the largest differential in the mid- and large-cap segments thanks to the heavy influence of Palantir and the broader Magnificent Seven. 

Beyond the U.S., emerging market (EM) equities meaningfully outperformed in September to finish ahead of their developed market counterparts for the quarter. The rally in Chinese equities was largely responsible for EM outperformance, with gains being driven by investor optimism about AI innovation, which bolstered Chinese technology and internet companies. Targeted government initiatives, easing trade tensions with the U.S., and significant domestic capital inflows also contributed to strength in China. Taiwanese and Korean equities also performed well in the period, overshadowing weakness in India, where equity markets were pressured by underwhelming corporate earnings and concerns about recently enacted U.S. tariffs. Foreign investor flows in Indian markets turned negative in the third quarter after being meaningfully positive in May and June. Performance in developed markets was held back by weakness in continental Europe (Denmark, Germany, Norway, Switzerland, France, and Sweden). European equities were hurt by weak corporate earnings, Trump tariff headwinds, and political instability, particularly in France, where the country’s prime minister resigned after losing a crushing confidence vote in parliament.
