Unfortunate News for Micron Stock and Sandisk Stock Investors | MU Stock | SNDK Stock

Parkev Tatevosian, CFA•Oct 14, 2026

Summary

Parkev examines the recent 2-4% decline in semiconductor companies such as Micron, SK Hynix, and Samsung following news from China. The Chinese memory manufacturer ChangXin Memory Technologies (CXMT) announced significant progress in a new memory cell design aimed at increasing density, a move that directly challenges the competitive advantages of established global leaders. Parkev notes that while such news from China frequently causes volatility in US and South Korean tech stocks, the immediate impact might be overstated given the current market conditions.

Parkev highlights that the memory industry is effectively sold out through 2025 and potentially into 2028. Even if CXMT's new architecture is introduced by the end of this year, Parkev argues that the financial impact on competitors like Micron won't be felt significantly until 2028. However, Parkev does caution that increased competition could lead to lower average selling prices (ASPs) due to pricing bands in long-term strategic customer agreements. Despite this, Parkev maintains a bullish outlook on the sector, particularly for companies with strong moats.

Micron (MU): Parkev states that Micron is performing exceptionally well, achieving unprecedented operating profit margins of over 80% for two consecutive quarters. Parkev calculates a fair value of $1,400 for Micron, which suggests an approximate 42% upside from the current price of $989 over the next 12 to 18 months.
SanDisk: Parkev provides an updated fair value estimate of 1,662 for SanDisk. Parkev notes that while the stock is slightly undervalued with an 11-12% upside, it carries higher risk and a smaller margin of safety compared to Micron, making it suitable only for investors with higher risk tolerance.
Nvidia (NVDA): Parkev argues that Nvidia remains a superior investment to Micron because of its wider competitive moat. Parkev states that Nvidia's technology is significantly ahead of the competition and harder to replicate, maintaining its status as one of Parkev's top recommendations despite Micron's impressive growth metrics.
