Did Stocks Lose Ground Last Month?

Ken Griffin hadn't noticed.

Citadel, the hedge fund giant led by Kenneth C. Griffin, told its investors on Wednesday that its two flagship funds rose 3.4 percent in January, according to a person briefed on the matter. The Standard & Poor’s 500-stock index declined 3.6 percent in that time….

The fixed-income fund, a relatively new business for the company, dating to 2011, logged a 5 percent return, the person briefed on the matter said.

The equities fund, which started in 2009, defied the broader slump in stocks, returning 2.9 percent in January.
