Steven Eisman, the strategist portrayed by Steve Carell in "The Big Short," told CNBC on Monday he believes President-elect Donald Trump's administration will roll back financial regulations.
Eisman, senior portfolio manager at Neuberger Berman, said he would be as "long as I can be" on financial stocks.
Eisman, whose bet against the subprime housing market prior to the 2008 financial crisis was depicted in the 2015 movie, told CNBC's "Squawk Box" he was "a little bit schizophrenic" on the markets.
He said the Dodd-Frank financial regulations, put in place after the financial crisis, is "good law" that should not be changed. However, he said he understands that under the Trump administration, change is likely to come.
Eisman said he bought the financial sector the day after the election and has invested more since then.
"I'm very long" the stock market overall, he added.
