That was fun for investors while it lasted.
Facebook stock Monday renewed its descent, dropping 11% before stabilizing a bit to finish the day down 8.3% at $20.79.
Monday's intraday decline was the steepest since July 27. It was so sharp it tripped Nasdaq's circuit breakers meant to shield investors from short-seller manipulation.
Sparking this week's selloff was a fresh report from Barron's that said the company is overvalued. Renewed concerns over how quickly the social-networking behemoth can capitalize on revenue from the exploding number of users who access the site via mobile devices and tablets contributed to the drop.
Tuesday morning, the selling continued.
Before the recent selling spree, shares of the Menlo Park, CA-based company had given back some 45% since its hugely hyped initial public offering on May 18.
But that decline isn't enough.
Barron's gave Facebook a best-case scenario of $15 per share.
