The S&P 500 ends a five-day record setting run after falling 0.4% to 1,626. The major economic news of the day came from the Labor Department reporting weekly jobless claims hit a new 5-year low last week, falling to 323,000.

Tesla (TSLA) electrified Wall Street today. Shares soared 28% hitting a new record high. Consumer Reports has given the company's Model S sedan a score of 99 out of 100. The magazine says the car will have bugs because it is so new, but still deserves the highest score of any vehicle tested. The rating comes just hours after Tesla reported its quarterly earnings.

"I'm no too worried about it," Wolff says in the attached video of the Fed's easy money policy; a policy that Warren Buffett refers to as a ''huge experiment." "If and when the U.S. economy really comes roaring back the Fed (will have) lots of ways to tighten appropriately."

On China, however, Wolff is blunt.

"My own view is that China's economy is in a bubble," he says, referring to the fast-growing Asian nation as "a dangerous place" to invest that is likely "to end very, very badly."
