Investors shifted record amounts out of U.S. stock funds and into bonds, while withdrawing money from emerging-market equities for a 15th straight week, according to Citigroup Inc.

U.S. equity funds had $24 billion of outflows in the week to Feb. 5, according to a report today from the research unit of the third-largest U.S. bank. Withdrawals from stock funds worldwide totaled $28.3 billion, the report said, citing data from EPFR Global, a fund research company in Cambridge, Massachusetts. Money managers plowed $13 billion into U.S. bond funds, accounting for most of the $14.8 billion that flowed into debt worldwide. All the figures for the period are record highs.

Bonds beat stocks last month for the first time since August as a slowdown in U.S. jobs growth and turmoil in emerging markets from China to Argentina drove demand for the safest securities. The Federal Reserve's decision to taper its bond purchases in January and again in February did more to temper the appeal of high-risk assets than reduce demand for U.S. debt.
