Erstwhile Microsoft CEO Steve Ballmer revealed on Friday that he had recently acquired a 4 per cent stake in troubled micro-blurting site Twitter.
The news came in a tweet from Ballmer who congratulated Twitter on its decision earlier this week to cut costs by lopping off 8 per cent of its workforce.
Ballmer, who is now the owner of basketball team LA Clippers, has become one of the biggest shareholders in Twitter. According to Forbes, the ex-MS chief's net worth is $23bn.
Shares in Twitter climbed nearly 5 per cent on the New York Stock Exchange at close of play on Friday, after Ballmer tweeted that he had bought a stake in the company. ®
