NYSE trader worried
A trader reacts as he works on the floor of the New York Stock Exchange (NYSE) in New York, U.S., March 18, 2020.
  • The FOMO trade has returned to the market as stocks rally 20% from their lows, according to Ned Davis Research.
  • But a lack of excessive optimism among investors means the stock market has yet to reach its peak.
  • "Even some investors who doubt the Fed can engineer a soft landing have begrudgingly gotten on board," NDR said.  

The stock market's 20% rally off its mid-October low has sparked a fear of missing out trade and pulled some investors off the sidelines and back into stocks, according to a note from Ned Davis Research.
