Stocks closed at fresh all-time highs on Tuesday, led by big gains in financials, after widely followed hedge fund manager David Tepper said he is "definitely bullish" on stocks. The Dow rose for a record 18th consecutive Tuesday.
The head of Appaloosa Management often has been credited with sparking the "Tepper Rally" in September 2010, when he told CNBC then that the Federal Reserve would support equity prices.
He again stated a position that liquidity would guide the markets, whether in the U.S. or other global markets where central banks are easing conditions. He also cited an improving economy, particularly housing and autos as reason to be bullish.
"What's going to make you bearish?" Tepper said. "I think every place is the place to be in the stock markets of the world."

The Standard & Poor's 500 climbed 1 percent to reach a new record high of 1650.34. The Dow Jones Industrial Average added 0.8 percent to close at 15215.25 while the Nasdaq climbed 0.7 percent to finish the session at 3462.61.
Morgan Stanley's Andrew Slimmon told CNBC, "Basically, what David Tepper is saying is the whole rally from the low has only been about earnings. We haven't had any P/E expansion until this year. And so we could have a combination of pretty good earnings plus P/E expansion. That makes for a pretty good market."
