Overall, history indicates that the buyback will have little impact on Microsoft's stock. While $60 billion sounds like a lot, it represents less than 2% of its shares outstanding and won't move the needle much.

Microsoft on Monday announced a $60 billion stock buyback program and a 10% boost to its quarterly dividend. The moves come as Microsoft faces pressure to show its spending on artificial intelligence (AI) is paying off.

Only three U.S. companies have ever announced buyback programs bigger than Microsoft’s latest — though the new dividend yield is still low relative to those of fellow Dow components.

Microsoft's share repurchase program, which has no expiration date, replaces its previous $60 billion authorization announced four years ago. Meanwhile, investors also cheered the news that shareholders of record as of Nov. 21 will receive a quarterly dividend of 83 cents per share, up from the current 75 cents a share.

Microsoft shares rose for the the seventh consecutive session on Tuesday, with the latest gains coming after the tech giant hiked its quarterly dividend by 10% and approved a $60 billion stock buyback.
