At this point, though, the good news is that stock funds are prospering pretty much across the board, Lemieux said.
Domestically, funds that invest in large capitalization growth stocks picked up $1.4 billion. So did funds that invest in "core" middle-sized companies.
In fact, the value of stocks has been rising for nearly four years. Since closing at 683.38 on March 6, 2009, the Standard & Poor's 500 broad index of stock market values has gone up 118%.
The Standard & Poor's 500 reached a five-year high at the end of December. Just last week, on January 22, it stood at 1,490, just 75 points away from its all-time high of 1,565, set on October 9, 2007.
It's too early to guess whether stock funds will all of a sudden be investors' favorite place to park their long-term assets, nonetheless.
"We'll have to see how this sustains" itself, Lemieux said.
