Cramer Calls for End to Micron-SK Hynix Correlation
TREE NEWS reports: Jim Cramer, the outspoken host of CNBC’s Mad Money, has taken aim at the tight trading correlation between Micron Technology (MU) and South Korea’s SK Hynix, arguing that the two memory chipmakers should not move in lockstep. “Micron stock does whatever SK Hynix does in Korea, and I dislike it,” Cramer said, highlighting a dynamic that has frustrated U.S. investors seeking independent price discovery for the Boise, Idaho-based company.
The remark comes after a series of sharp selloffs in semiconductor equities, during which Micron and SK Hynix have tracked each other closely. As two of the world’s largest suppliers of DRAM and NAND memory, both companies are exposed to the same cyclical forces—AI-driven demand, inventory corrections, and capital expenditure cycles—but Cramer’s complaint centers on the timing and magnitude of their moves, which often see Micron react to overnight trading in Seoul before U.S. markets open.
Why the Correlation Exists
The linkage is structural. SK Hynix is a key bellwether for memory pricing, and its earnings guidance often sets the tone for the entire sector. When the Korean giant warns of softening demand or announces aggressive capacity expansions, Micron’s stock frequently mirrors the reaction, sometimes within hours. This has led to what some traders describe as a “follow-the-leader” dynamic, where U.S. investors wake up to a Micron that has already been priced by Asian session moves.
- Global memory market: Micron and SK Hynix, along with Samsung, control the vast majority of global DRAM supply.
- AI demand: High-bandwidth memory (HBM) used in AI accelerators has become a key growth driver for both firms.
- Currency and geopolitics: Won-dollar fluctuations and U.S.-China tech tensions add layers of volatility.
Implications for Investors
For U.S. investors, the correlation presents both risk and opportunity. On one hand, it means Micron’s stock can be whipsawed by overseas developments that have little to do with its own fundamentals. On the other, it creates potential arbitrage opportunities for those who closely monitor Korean market hours. Cramer’s frustration reflects a broader desire for Micron to be valued on its own merits—particularly its growing HBM business and U.S. fab investments—rather than as a proxy for Asian memory sentiment.
Analysts note that decoupling may be difficult in the near term. Until Micron’s customer base and product mix diverge more meaningfully from SK Hynix’s, the two will likely continue to trade in tandem. However, increased U.S. domestic production and long-term supply agreements with American hyperscalers could gradually reduce the sensitivity to Korean market moves.
Forward Look
As the AI boom continues to reshape semiconductor demand, the Micron-SK Hynix relationship will remain under scrutiny. Investors should watch for signs of divergence—such as Micron’s HBM3E ramp and its ability to command premium pricing—that could finally break the correlation Cramer dislikes. For now, however, the memory market’s global nature means that what happens in Seoul will likely continue to echo in New York.
