Around midday, shares of the microblogging company were down 10.4 percent to $38.18 on the New York Stock Exchange, after earlier falling to $37.24, its lowest price since its November 7, 2013 introduction on Wall Street.
Though still above its initial public offering price of $26, Twitter has lost more than half its value since peaking at $73.31 in December 26.
Investors were troubled by data showing the company had 255 million active monthly users in March, below the 257 million projected by Wall Street, said BMO Capital Markets.
It looks like the actual monthly users is not meeting Wall Street expectations and the stock is getting pounded because of it. Twitter needs to do something splashy like buy out Kik or Snapchat or something in order keep themselves relevant.
