Twitter Creator Jack Dorsey Is No Longer a Billionaire

Forbes: Jack Dorsey is learning how difficult it is to be the CEO of not just one, but two, publicly traded companies. The Twitter and Square CEO is no longer a billionaire as shares in his two tech companies dropped Wednesday morning. After the opening bell, Square shares dropped below $9.00 for the first time since the company started trading publicly in November. Twitter, which hit its lowest price this year just after Wednesday’s opening bell, is down 57% in the past 12 months.
