US buyback announcements are running at a record pace this year, though more than two-thirds of the $261 billion in commitments are spread across only five companies, according to JPMorgan Chase & Co. strategists.

Chevron Corp.’s $75 billion leads the way, followed by Meta Platforms Inc. with $40 billion, Goldman Sachs Group Inc. with $30 billion, and Booking Holdings Inc. and Salesforce Inc. with $20 billion each, a team led by Dubravko Lakos-Bujas wrote in a note.

While announcements of buybacks are scaling new peaks so far this year, execution of them has been falling. According to the strategists, stock repurchases were down 20% in the fourth quarter, with the pace decelerating since the first quarter of last year.

Buybacks have been a key source of share demand in the US over the past decade. But given current uncertainty over economic growth, companies may seek to preserve cash, while repurchases have also become a target for tax increases by the Biden administration.

Share buyback announcements by S&P 500 companies over the last 12 months have totaled $853 billion, compared with a peak of about $1 trillion in May 2019, the strategists said.
