"Twitter plunged just over 11 percent Thursday after a report from an investor group that called the company "toxic" to advertisers and investors.

Citron Research, led by investor Andrew Left, wrote that Twitter is "uninvestible" and "advertisers will soon be forced to take a hard look at all sponsorships with Twitter."
