New York (CNN Business) The aging bull market will turn 10 years old next month, but the rally may still have some legs left.

Matt McCall, founder and president of Penn Financial Group, thinks the S&P 500 will wind up with gains of about 25% at some point this year. The index is already up nearly 9% so far in 2019.

McCall will be talking about all this and more with CNN Business editor-at-large Richard Quest on the Markets Now live show Wednesday at 12:45 pm ET.
