Trading the Pop in Bank of America Stock

A pop in Bank of America stock midday Tuesday isn't enough to sell, Stephen Weiss of Short Hills Capital said.

"I still think it's cheap on a price-to-book basis, and I'm still positive on the economy, which means that net interest margins will increase. They'll make more money," he said. "I think you're seeing a turn in M&A also."

On "Fast Money," Weiss said that he remained positive on the stock long-term.

Bank of America stock traded at $12.27, up 2 percent at 12:30 p.m. ET.

Josh Brown of Fusion Analytics said that now wasn't the time to sell.

"The thing is, I don't know a lot of people who are long in the stock that are looking to part with it just yet. It really seems to be strong even on down days," he said.

"The dips are being bought really quickly in this name, and until that dynamic changes, I'm not sure why anyone would want to walk away just yet."
