In addition to being a rough year for the stock market, it's been another tough period for active managers.
Just 32 percent of those who run mutual funds that focus on large-cap stocks have managed to top their measuring stick this year, according to tabulations from Goldman Sachs, which uses a sample of 684 funds with $1.7 trillion of assets under management (of the $7 trillion overall of actively managed funds).
The news is worse elsewhere: A mere 8 percent of large-cap growth managers have managed to beat their Russell 1000 Growth Index, while only 12 percent of large-cap value managers are ahead of their Russell 1000 Value barometer.
Interestingly, the small-cap space is the only sector where managers are keeping up, as 80 percent of core funds have beaten the , which has dropped about 5 percent year-to-date.
Active managers trade stocks in and out of portfolios, while passive investing involves tracking basic indexes like the S&P 500 or one of its sector sub-indexes, such as financials or technology.
There appear to be a few culprits this year in the active underperformance: an overweighting of consumer discretionary stocks, which have done poorly this year, and an underweight of real estate investment trusts, which have prospered.
More broadly, the S&P 500 has gained less than 2 percent and has seen several spikes and drops as high-profile investors continue to call for a sharp market correction. It all adds up to an uncomfortable environment that seems tailor-made for choosing indexes but often sees market participants seeking out stock pickers.
"When you're in a volatile market like this year, passive is going to do better," said Nadav Baum, executive vice president at BPU Investment Management. "When you're in the market and you get three or four months of negative returns, at that point investors make the cardinal mistake of getting out because they're nervous. If they have an active manager, they feel like someone's watching out for them."
As far as where the money is headed, the choice has been pretty clear.
Investors have piled about $75 billion in total equity funds, but actually have withdrawn a net $1 billion from actively managed funds. ETFs, meanwhile, have been raking in cash, with net inflows of nearly $40 billion, according to XTF.com.
