Billionaire Ackman Increases Stake in Microsoft Amid Fears
- Investment Positioning: Billionaire investor Bill Ackman disclosed that his hedge fund, Pershing Square USA, has increased its stake in Microsoft, selling most of its holdings in Alphabet, which reflects confidence in Microsoft's future amidst current market valuation concerns.
