Sandisk Just Announced a $14 Billion Stock Buyback Authorization: Warren Buffett Has a Warning Investors Shouldn't Ignore

Sandisk, a leading memory chip maker, has experienced remarkable growth in 2026, with its stock outpacing the broader S&P 500 index. The surge in demand for its chips can be attributed to the increasing investments in AI infrastructure, leading to a shortage that has enabled the company to raise prices and achieve impressive profitability.

As a result, management has decided to return a portion of those profits to shareholders, as evidenced by the company's announcement of a $14 billion increase to its share-repurchase authorization in mid-August. This brings the total remaining authorization to $15.5 billion, representing more than 7% of Sandisk's current market capitalization.

However, while stock buybacks can be beneficial for shareholders in the short term, there are concerns about their long-term impact. Warren Buffett, the renowned investor, has cautioned investors against overly aggressive share repurchases, suggesting that they may not always be in the best interest of all shareholders over the long run. It is essential for Sandisk investors to carefully consider this warning and evaluate the potential implications of the company's stock buyback plan on their overall investment strategy.
