Why are Micron and SanDisk stocks rising today?

What happened

Memory stocks recovered on Monday after a selloff the previous week. Micron shares gained around 6% and SanDisk shares advanced 7%. TSMC said it does not comment on market rumours and remains focused on logic chips, following a report that it was exploring 3-D DRAM production at Nvidia’s request.

Confirmed

Global impact / market context

The reported possibility of TSMC making memory chips raised concerns that more competition could push memory prices to peak sooner. TSMC’s stated focus on logic chips eased that concern, potentially supporting expectations for memory makers’ pricing and future revenue, though the article does not establish any change in supply.

Analyst inference

The article places Monday’s gains after a difficult stretch: Micron had lost nearly 30% of its market value over the previous month, and memory stocks had sold off the prior week. The rebound followed TSMC’s response, but the article gives no evidence that sector risks have disappeared.

Confirmed

What to watch

1. Watch for any further TSMC statements or confirmed plans involving memory chips; actual entry could add supply and increase competition, while no entry would leave that concern unconfirmed. Analyst inference
2. Track memory-chip pricing and demand updates, because weaker prices could reduce chipmakers’ revenue even if TSMC does not enter the market. Analyst inference
3. The article reports TSMC’s statement that it remains focused on logic chips and does not comment on market rumours; it does not confirm a memory-production decision. Confirmed
