U.S. stock mutual funds’ inflows slowed to $7.17 billion in October after gaining $10.22 billion in September, but world bond fund inflows remained stable during the same period, Dow Jones Newswires reports.

Experts at Lipper were somewhat perplexed by October’s stock fund flows, as investors poured money into other types of equity investments during the same timeframe. Domestic bond funds were the big losers last month; investors withdrew roughly $2.38 billion from the asset class. But world bond funds propped up the broader fixed-income category last month by attracting $4.79 billion and $4.12 billion in September, according to the Investment Company Institute.

Investors fed $3.47 billion into to hybrid funds that invest in a mix of both stocks and bonds, in October, a sharp upturn from $2.83 billion in September. In total, stock and bond mutual funds netted a combined $14.09 billion in October, almost $2 billion less than September.
