Sandisk Breaks to Another Record High as AI Hopes Outrun Valuation Worries

Sandisk jumped again today, closing near a new record high around $770 on slightly above‑normal trading volume. Buyers are still clearly in charge, even after the stock has risen roughly twelvefold over the past year and more than tripled in two months.

The main engine is the same: big optimism that AI will keep demand for Sandisk’s flash chips very strong, backed by recent results showing much better profit margins and multi‑year customer deals. Institutions (the “big money”) are still adding positions, which helps keep the uptrend going.

At the same time, analysts are starting to say the price has outrun their models, and the overall market is nervous about inflation and interest rates. The company’s last year of official numbers still shows an accounting loss, heavy obligations, and a very cyclical business, so the story depends on that AI boom and high margins lasting.
