As money surges into the market, is it time for savvy investors to cash out?
That's what a report from TrimTabs suggests, at least on a near-term basis. The investment research company reported on Sunday that investors have added $46.8 billion to equity mutual funds and exchange-traded funds in March, the most for any month since October 2013.
"Fund flows data does not bode well for U.S. equities in the short term," TrimTabs concludes.
Indeed, investors often take fund flows to be a contrarian indicator. The basic idea is that once everyone buys, there's less money left to go into the market. Additionally, heavy buying could be seen as a sign of investor exuberance, indicating that stocks are in "overbought" territory.
Indeed, TrimTabs adds that flows into and out of leveraged ETFs (which move twice or three times as quickly as the underlying set of stocks) are "also worryingly upbeat," with leveraged short ETFs redeeming assets for the second straight week, and leverage long ETFs issuing assets for the fourth straight week.
Still, not everyone finds the buying to be quite so worrisome.
"I don't think it signals a top of any sort. It's a lagging indicator. It's garbage, as far as I'm concerned," said David Seaburg, head of equity sales trading with Cowen & Co.
