American Economy Seen Accelerating as ETFs Favored S&P 500

The U.S. economy is showing signs of improvement and buyers of exchange-traded funds are taking note.

Investors have sent $5 billion to funds tracking American stocks since the beginning of April, equal to 39 percent of all equity flows for the month, according to data compiled by Bloomberg. That compares with $600 million from January through March, or 22 percent of the total. Funds tracking the Standard & Poor’s 500 Index and energy stocks got the most money.
