Financial stocks may have wiped out their gains for the year, but despite the negative sentiment, David Ellison told CNBC on Wednesday he's still bullish on the sector.
Financials were once the most popular postelection trades. However, on Wednesday, the S&P SPDR Financial Select Sector ETF (XLF) turned negative for the year as investors grew wary about President Donald Trump's domestic and foreign policies.
"The reason to own them is still there. You've got a good economy. Credit's good. The prime has moved up 75 basis points in the last year," the portfolio manager of Hennessy Large Cap Financial Fund said in an interview with "Closing Bell."
Therefore, Ellison sees a buying opportunity as the sector moves to somewhere in between now and its postelection run-up.
"The fundamentals are good. The valuations are reasonable for a lot of the companies."
However, analyst Dick Bove told CNBC earlier Wednesday banks are a "very treacherous area" to invest in and investors should get out now.
