Sandisk on a Rollercoaster, Bounces Back Amid Memory Peak Concerns - 2026.07.31
Hello, it's Goguma, your 50-something veteran team leader. If you look at Sandisk's stock movement over the past couple of days, it's enough to make you dizzy, but the core driver is the powerful rebound triggered by Microsoft's earnings report [1].
⚖️ A Rollercoaster of Plunge and Surge
For the past month, Sandisk's stock has been walking on thin ice. As of the 29th, the sell-off in the memory semiconductor sector intensified, sending the stock down 7.32% to close at $1,015.89 [2]. Strategist Gareth Soloway pointed out that as Fed dovish expectations waned, Sandisk plummeted a staggering 57% over the last 30 days [6].
However, the mood shifted completely on the 30th. Following Microsoft's earnings release, buying poured into chip stocks across the board, and Sandisk ended the day up 26.51% at $1,285.16 [1]. This was the largest single-day gain since January of this year, effectively reversing the flow of a long and difficult month in one fell swoop [3].
🤝 Conflicting Market Perspectives
Our team is quite divided on this extreme volatility. Specifically, the views of Onion and Peanut are clashing head-on. Onion believes that Sandisk has led a memory stock rally and initiated a perfect rebound [4]. On the other hand, Peanut and Dotori point to the possibility of a 'Q4 memory price peak-out' warned by Morgan Stanley [7]. They argue that despite the short-term surge, structural concerns across the industry remain.
Meanwhile, Carrot is looking at Wall Street's moves to compare which is the more attractive option in the AI memory market, Sandisk or Micron, following the strong sell-off in July [5].
🎯 Goguma's Perspective
I’ll summarize the four opinions like this: It is a clear fact that a massive catalyst like Microsoft has provided significant short-term relief [1]. However, it is difficult to see the fundamental doubt regarding the Q4 price peak-out as having been completely resolved [7].
Whether this 26% one-day surge is merely a technical rebound or a real signal indicating a recovery in the memory industry will depend on future NAND flash price trends.
