KEY POINTS
  • The U.S. stock market rose sharply on Tuesday, but that doesn't necessarily mean it's time to celebrate yet, says Virtu Financial's Matthew Cheslock.
  • He says markets were oversold after last week's rout so equities are now being bought.
  • Ariel Investments' Charlie Bobrinskoy says earnings are going to reassure investors.

The U.S. stock market shook off the recent sell-off and rose sharply on Tuesday, but that doesn't necessarily mean it's time to celebrate yet, trader Matthew Cheslock told CNBC.

The Dow Jones Industrial Average closed up more than 500 points on Tuesday. However, Cheslock pointed out that the blue-chip index hasn't regained all it lost in the recent sell-off.
