There's no cause for concern, but stock levels suggest that investors should be buying protection, Shelter Harbor Capital's Brian Kelly said Thursday.
"I came in long today. I stayed long," he said. "I don't think there's any reason to be terribly concerned, but you need to buy puts. I will absolutely say that. We're at five-year highs here. Volatility's at low. You have to protect yourself."
On "Fast Money," Kelley added that central banks around the world were looking to devalue currencies, "making equities catch a bid in every country."
Transports, airlines, housing, cyclicals and pharmaceuticals traded around 52-week highs.
EmergingMoney.com's Tim Seymour noted that stocks appeared strong on a fundamental basis and S&P 500 earnings were beating expectations.
"I think the housing sector is being supported by the banking sector," he said. "I know that seems a little bit opposite, but I think therefore we have the leadership in this market that can take us farther."
OptionMonster's Jon Najarian said that he "saw a lot of money flowing out of bonds" and noted that "people were buying puts like crazy."
