US equity funds see highest-ever inflows in July

By Ansuya Harjani

August 4 (CNBC) &#8212 U.S. equity funds saw a record inflow of $40.3 billion in July, according to data from TrimTabs, as the S&P 500 and Dow Jones Industrial Average scale new heights in what some are calling an “invincible summer” for the country’s stocks.

“Fund flows in the past two months were by far the most volatile we have ever measured. After ignoring equities and dumping bonds at a record pace in June, fund investors poured record sums into U.S. equities and continued to sell bonds in July,” the investment research firm wrote in a report published late Sunday.

Fund investors ended their “love affair” with bonds this summer, pulling $21.1 billion out of debt mutual funds and exchange-traded funds (ETFs) in July, after record outflows of $69.1 billion in June. The outflows in June and July brought an end to 21 straight months of inflows.
