One of the top banking sector analysts on Wall Street said Tuesday that the big bank stocks are in a strong position as their stocks have climbed in recent weeks.

The SPDR S&P Bank ETF climbed again on Tuesday and has risen nearly 20% since May 13 in the face of widespread unemployment and concerns about small businesses going under. Wells Fargo's Mike Mayo said on "Halftime Report" that there is a reason to believe the bank stocks could go even higher.
