"I also think that the news flow on this could start to change," he said, "where people start to want Tesla's model, particularly in Arizona and other places."
Shares of Tesla plummeted 3.81 percent, closing at $220.17, along with other momentum stocks such as the iShares Nasdaq Biotechnology exchange-traded fund. Those shares fell 2.76 percent to end the day at $239.23.
Kelly said that it was time to look at some of the weakened momentum stocks because the U.S. bond and copper markets didn't confirm the weakness, and he also pointed to strong China PMI numbers overnight.

Tim Seymour of EmergingMoney.com also pointed to solid Chinese economic numbers, saying that a pullback in a few momentum stocks was "not a reason to run for the hills."
Karen Finerman of Metropolitan Capital Advisors, who was long IBB and looking to add to her XBI position, said that biotech was "an interesting trade."

"It's getting close, I think," Finerman said.
StockMonster's Guy Adami said that he didn't see a bubble in biotech, despite a tough day for the sector.
