Whoops: Steve Ballmer Might Be Regretting His Twitter Investment... Or Is He?

Back in October, Microsoft Corporation MSFT’s former CEO Steve Ballmer acquired a 4 percent stake in Twitter Inc TWTR, which made him a bigger shareholder than the latter’s CEO Jack Dorsey.

Last Wednesday, Ballmer was at the Fortune Brainstorm Tech dinner in San Francisco, and confessed that his experience with Twitter had helped him learn a valuable lesson: he does not want to be an investor.

Despite the shocking revelation, and the fact that, since the end of October, Twitter’s stock has lost about 41.5 percent, his confidence in the social media giant remains unaltered. “I think it is a very good brand, but its cost structure and product can be improved. It’s better to invest in things that have a path to improvement,” the owner of the Los Angeles Clippers told Fortune’s assistant managing editor Adam Lashinsky.

In fact Ballmer seems like a man that stands by his choices. The former executive also holds shares of Microsoft, and said he saw “no reason to sell the stock” unless he gave it away or believed it was going to tank. “I prefer to be a holder and I believe in that,” he assured.
