Hedge funds stay bullish despite growth stock rout

There are surprisingly few signs that equity hedge funds have made big changes to their portfolios following a brutal recent move away from stocks with high potential for growth, especially technology companies.

Hedge funds have even downsized their short positions, or bets on stocks to decline. Sectors where short positions decreased over the week of April 7 included information technology (down 8.86 percent); telecommunications (-4.95 percent); financials (-5.70 percent); and consumer discretionary (-10.29 percent), according to a recent UBS report.

Overall, the average equity focused fund increased its market exposure from 38 percent to 40 percent net long, according to a separate report from Bank of America Merrill Lynch. "Net long" means that a fund's bets on the appreciation of the market outweigh the value of their shorts.

"Despite recent challenges in the markets, funds are maintaining exposure and we haven't seen signs of a widespread liquidation," said Jon Kinderlerer, who analyzes Credit Suisse's hedge fund client portfolios as head of risk and portfolio advisory for the bank's prime brokerage division.

Whatever portfolio tweaks were made, it hasn't worked yet: The average stock-focused fund fell 1.23 percent in the first week of April, according to the Bank of America report.
