Former Microsoft chief executive and owner of the NBA’s Los Angeles Clippers Steve Ballmer recently took a 4 percent stake in Twitter, according to tweets posted late last night. He also praised the company and newly installed CEO Jack Dorsey for the launch of Moments and its latest moves around innovation, which also involved the layoffs of 8 percent of its workforce.

It’s believed that Ballmer bought shares over the past few months. Ballmer reportedly confirmed the move in an email to Bloomberg Business today. We’ve reached out to Twitter for comment, but it appears that the company won’t be notified if a stake is less than 5 percent, according to MarketWatch’s reporting.

The unverified account appears to be in fact Ballmer’s, as his verified one, where he represents the Los Angeles Clippers, points followers to this new one. However, neither account is exactly prolific when it comes to tweeting.

Following the news, Twitter’s stock is up 1.88 percent after opening up at $30.08.
