Citigroup's Federal Reserve stress test marks left some CNBC "Fast Money" traders singing its praises.
"This is arguably the cheapest bank with the most to gain here," said trader Tim Seymour, who owns stock in the bank.
The bank passed the second round of the Fed's stress test after failing to gain approval last year. The Fed on Wednesday rejected capital distribution strategies from U.S. units of Deutsche Bank and Santander while saying Bank of America's approval was contingent on the bank submitting a revised plan.
The Fed approved capital plans from 28 of 31 tested banks outright as part of the annual test. It gauges how well banks manage risk and their ability to withstand a potential economic shock.
Trader Karen Finerman currently has more exposure to Bank of America than Citigroup. She will consider changing that weighting after Wednesday's results, she said.
Citigroup said it gained Fed approval for a buyback of up to $7.8 billion in common stock starting in the second quarter of this year. Its shares were up almost 3 percent in extended trading on Wednesday.
Wells Fargo and U.S. Bancorp hovered around $54 and $44, respectively, in after-hours trading on Wednesday. Both banks were cleared for dividend increases.
A more expensive name, Goldman Sachs, may also rally in the short term, Adami said. The stock could surge into April, when the bank is expected to report its first-quarter results.
