Warren Buffett's Berkshire Hathaway has sold off $1.21 billion worth of shares in VeriSign, the company behind internet domain name services like .com and .net. The move was disclosed in a regulatory filing with the SEC, signaling a major shift in Berkshire's investment strategy.

Editor’s Note: While this isn't necessarily bad news for VeriSign, it does raise eyebrows since Buffett is known for long-term holdings. Investors might wonder if Berkshire sees less growth potential in the company or is simply rebalancing its portfolio. Either way, it's a big move worth paying attention to.
