NEW YORK (TheStreet) -- U.S. markets fell Thursday amid mixed economic data, while retail stocks dropped on disappointing earnings. Small caps, as measured by the Russell 2000, were off more than 1.6%.

David Tepper, founder of $20 billion hedge-fund firm Appaloosa Management, described markets as "dangerous" and said he was worried the U.S. economy wasn't growing fast enough. "I think it's nervous time," he said at the SkyBridge Alternatives Conference in Las Vegas on Wednesday, noting stocks may grind higher in the near term.

"If the S&P 500 fails to extend strongly above 1,900, the bulls may see this as an indication that there is a lack of buyers, which would leave the market vulnerable to a break below 1876-1885, and potentially reignite talk of a significant correction," notes Sam Stovall, managing director at S&P Capital IQ.
