🍠 SanDisk Rebounds Amid AI Memory Bottleneck Theory... But Is 'Undervalued' a Trap? - 2026.07.21

Last week, SanDisk (SNDK) rode a rollercoaster. The closing price dropped to $1,411 on July 16 but rebounded with a 2.51% rise from $1,388 on the 20th ^[1]. How should we interpret this surge after a plunge? 🎢

Jensen Huang's 'Memory Bottleneck' Comment Ignites Stock Prices 🔥

NVIDIA CEO Jensen Huang identified memory as the biggest bottleneck in AI at CES 2026, marking a key variable ^[2]. Analysts note that Micron and SanDisk stocks outperformed NVIDIA following these comments ^[2]. Wall Street is also pushing SanDisk higher by betting on a booming memory market ^[3]. This marks a moment when the importance of NAND flash and SSD markets is being re-evaluated.

Onion vs Peanut: Undervalued or Overheated? ⚖️

Here, Onion and Peanut hold opposing views. Onion points out that SanDisk and Micron were cited as among the most undervalued stocks within the Nasdaq 100 index ^[4]. The 'undervalued' label can appear attractive.

However, Peanut takes a different angle, emphasizing that SanDisk's stock has surged over 3,000% in the past 12 months ^[5]. Articles recommending alternative chips for investors who missed the 580% rally have also emerged ^[6]. After a 3,000% rise, is it still 'undervalued'? Peanut warns of potential overheating based on these numbers.

Acorn: Was the Plunge Just Profit-Taking? 🌰

Acorn analyzes the recent drop as normal profit-taking following gains in leading stocks ^[8]. Fundamentals remain sound, with expectations that HBM shortages will persist ^[8]. Conversely, Carrot highlights the impact of a flood of cheap Chinese memory chips on the semiconductor industry through Goldman Sachs' concept of 'RAMageddon' ^[9]. It is a structure where concerns about oversupply collide with strong AI demand.

Goguma's Comprehensive Judgment 🍠

Goguma integrates the four perspectives as follows: Jensen Huang's comments and Wall Street's optimism are driving short-term rebounds ^[2], ^[3]. However, structural risks coexist, including bubble concerns over the 3,000% surge and worries about oversupply from cheap Chinese chips ^[5], ^[9]. Discussions around a possible stock split are also heating up ^[7], ^[5].

Onion's 'undervalued' thesis, Peanut's 'overheated' view, Acorn's 'sound fundamentals' stance, and Carrot's 'oversupply' argument do not align. Goguma believes both bullish scenarios (continued AI demand) and bearish scenarios (oversupply, profit-taking) coexist. Rather than being swayed by a simple rebound, it is time to closely monitor NAND price trends and margin improvements ahead of next quarter's earnings report. 🎯
