Bank earnings started to come in on Thursday, with both JPMorgan Chase and Citigroup reporting results before the bell.
JPMorgan posted third-quarter earnings and revenue that beat analyst expectations. However, the bank reported a 27 percent year-over-year decline in fixed-income trading revenue. The stock closed down nearly 1 percent but is still up 11 percent this year.
Citigroup also reported results that beat expectations. However, concerns about rising credit card costs drove the stock lower by more than 3 percent.
Michael Block, chief strategist at Rhino Trading Partners, is bearish on the banks in the near- to intermediate-term.
While a steepening yield curve and higher rates are good for the sector, he doesn't see that catalyst playing out.
"I don't think bond yields are going a lot higher. The Fed will probably raise in December and that's about it. They're worried about low inflation being more than transitory," he told "Closing Bell."
He is also concerned about what's happening in credit cards. Bank write-offs on credit card debt had been getting better and then leveled off, he said. Now, for the first time it is getting worse, he noted.
"Something is happening here," Block said. "We used to worry about mortgages. We used to worry about home equity loans, student loans. This is the next phase. Consumers are getting pinched a little bit in certain demographics, and it's going to be an issue."
However, if he takes a longer-term view, or "Warren Buffett approach," to the sector, he is bullish. But he wouldn't buy just yet.
"If you are bullish you're going to get a better chance to buy these things later this year, early next year," said Block.
Bank earnings will continue on Friday, with Bank of America and Wells Fargo among those set to report.
