Twitter CEO Jack Dorsey to resign, according to CNBC report, sparking stock surge

Twitter’s stock, which has consistently underperformed the market, jumped more than 10 per cent at the opening bell on Monday.

Twitter did not immediately respond to a request for comment from The Associated Press early on Monday (early Tuesday AEDT).

Mr Dorsey is also the top executive at Square, a financial payments company that he founded, and some big investors have openly questioned whether he can be effective leading both.
