$27 Billion in Buybacks: 3 Stocks Betting Their Strong Runs Aren't Over

Sandisk, Phillips 66 and MetLife have collectively added $27 billion in new share-repurchase authorization. Each company enters the buyback discussion from a different backdrop, spanning AI storage, refining and insurance. Investors now have to consider how cash generation, valuation and industry conditions could shape the impact of those buybacks.

Several industry giants that have seen impressive share price performance in 2026 recently made big-time buyback announcements. Share repurchases can do more than reduce share counts—they can also signal that management sees enough cash-flow strength and balance-sheet flexibility to keep returning capital after a strong run. Three top firms have added $27 billion in buyback capacity, indicating confidence in their outlooks and cash generation. This includes a $14 billion authorization from one of the best-performing stocks of 2026, which has cemented itself as a critical player in AI infrastructure.

The company noted at its recent Investor Day that it will return 100% of its excess cash to shareholders. As SanDisk does not pay a dividend, this will come through buybacks In turn, SanDisk is indicating that it plans to spend billions on buybacks even after the astonishing rise in its share price. This signals considerable confidence going forward and can allow the company to add a meaningful tailwind to per-share metrics.

Although not as stunning as SanDisk’s 2026 gain, oil giant Phillips 66 has also put up an extremely strong performance, up more than 80%. The company generated adjusted earnings of $3.8 billion in its latest quarter, up from just $207 million in Q1. Notably, margins on refined products are soaring. Disruptions in the Middle East have not only damaged the worldwide supply of crude oil, but also that of refined products like gasoline. This comes as significant refining capacity resides in the Middle East. In turn, refineries that continue to operate, like those in the United States, benefit from the imbalance of supply and demand. Notably, crack spreads on diesel fuel, which measures the difference between the price of crude and refined diesel, recently...
