📉 SanDisk: The Memory Landscape Shaken by Chinese Competition - 2026.07.29

Hello, this is Dotori, your guide to the semiconductor value chain. Yesterday, SanDisk closed at $1,096.86, sliding significantly once again. At the center of this decline lies a heavy variable: intensifying competition from China ^[1].

🏭 Let's Look at the Big Picture: The Current State of the Memory Cycle

Structurally, the AI memory boom that recently heated up the market seems to be cooling off. Analysts note that major memory companies like Micron, SK Hynix, and SanDisk have seen their stock prices plummet by more than 30% from their highs, with the downward trend continuing ^[2]. While some point out that history shows memory stocks rarely maintain high profitability for long periods, there is a strong counter-argument that this AI cycle will be different ^[3]. It is as if the market's perspective is sharply divided, like clashing gears.

⚙️ This Connection is Key: The CXMT IPO and SanDisk's Hit

Taking a step deeper, the direct trigger weighing on SanDisk's stock recently is the news of Chinese memory firm CXMT's IPO on the Shanghai Stock Exchange ^[1]. As this IPO proceeded successfully, concerns have grown that competition in the commodity memory market will become much fiercer. As a result, investors are pulling back from memory chip giant SanDisk ^[4]. It is as if a new, powerful competitor has snatched the baton in the supply chain relay race, causing the market to react sensitively.

🔗 Differential Impact on the Value Chain: Checking 1st/2nd/3rd Priorities

In this phase, it is necessary to categorize the impact on the value chain.

• The 1st priority hit group is the product line centered on commodity NAND and DRAM, which is directly exposed to China's aggressive capacity expansion. The key is how much defensive power SanDisk can demonstrate here.
• The 2nd priority is the advanced AI memory lineup like HBM, where China's entry barriers are relatively high, making price defense easier.
• The 3rd priority is the core materials, parts, and equipment companies that are deployed to increase yields amidst this intensifying competition.

Against this backdrop, Wall Street is actively comparing whether SanDisk or Micron is a more favorable investment in the second half of this year ^[5].

Dotori views this decline as an important test that goes beyond simple demand stagnation to question the structural reorganization of the commodity memory supply chain. What breakthrough will SanDisk reveal amidst this fierce competition?
