$Tesla(TSLA.US)$ As the Russell 1000 index rallied 6.9% during the month, only 32% of large-cap active funds managed to outperform the benchmark, according to data from Bank of America. That’s the lowest beat rate in four months. The group lagged the benchmark by 0.66 percentage points on average, marking the weakest month since August 2020.

Part of the underperformance can be attributed to active funds’ general underweight in surging names like Tesla. Shares of the electric car maker returned 43.7% in October to surpass $1 trillion market cap, and now rank as the fourth-largest stock in the S&P 500 index behind $Microsoft(MSFT.US)$ , $Apple(AAPL.US)$ , and $Amazon(AMZN.US)$ . Tesla alone has lifted the index by roughly 1 percentage point last month.
