"Warren Buffett's Latest Moves: Insider Buying and Sure-Thing Stock Bet"

Warren Buffett and his team at Berkshire Hathaway have been investing in Liberty SiriusXM, a tracking stock that represents Liberty Media's stake in Sirius XM. The stock offers a discount compared to buying Sirius XM directly, and Berkshire has been steadily increasing its investment in it. Sirius XM's subscription-based revenue model and potential for growth make it an attractive investment, especially considering its low valuation. Despite not being on The Motley Fool's list of top stocks, Liberty SiriusXM presents an opportunity for investors looking to follow in Buffett's footsteps.
