The majority of active large-cap funds have underperformed the broader market, but this may benefit the broad equities market and stock exchange traded funds as active managers try to play catch-up.

Only 23% of large-cap mutual fund managers have outpaced the S&P 500 index this year, generating some of the worst performance results in the past decade, reports Steven Russolillo for the Wall Street Journal. [Active Stock Pickers Trail Passive S&P 500 ETFs]

The results are rather surprising, given that correlation between individual stocks in the S&P 500 have declined to pre-financial-crisis levels, which should make it easier for active investors to pick out winners.

Consequently, David Kostin, chief U.S. equity strategist at Goldman, argues that the underperformance could be a boon for the broader market through the rest of the year.

Most large-cap fund managers “will be forced to re-evaluate their portfolios or embrace the likelihood of drafting very disappointing year-end letters,” Kostin said in the article.

Goldman believes that the S&P 500 should keep rallying through the end of the year as more active funds feel compelled to chase performance to boost returns before the calendar-year ends. Year-to-date, the SPDR S&P 500 ETF (NYSEArca: SPY), the iShares Core S&P 500 ETF (NYSEArca: IVV) and Vanguard S&P 500 ETF (NYSEArca: VOO) have increased about 9.6%.
