If you've been following the stock market this year, you know all too well about January's parabolic 8% gain.
It didn't end well and was followed by a 10% correction in February.
With the stock market now well above its January high, Charles Schwab's chief investment strategist Liz Ann Sonders sees some similarities between the current market environment and the euphoria seen in January.
"[We're] starting to see some of that same froth [as January]," Sonders noted. "I am a little bit concerned."
But Sonders noted that the current euphoria could persist for some time.
