The South Korean stock market experienced a shock. On July 13, shares of SK Hynix, one of the world's largest memory chip manufacturers, plunged by 15.4% — a record drop in the company's history. The collapse was the culmination of a massive sell-off that unfolded after an impressive rally fueled by the frenzy surrounding artificial intelligence.
Since reaching an all-time high at the end of June, the market capitalization of the "Korean NVIDIA," as SK Hynix is often called, has shrunk by approximately 38%. The company's market value lost nearly 200 billion dollars, declining from a peak of 1.25 trillion to about 1.05 trillion dollars. In July alone, shares fell by 30%, and the current month risks becoming the worst for them since October 2008.
The key reason for such a sharp correction was profit-taking by investors, who began to reassess their expectations regarding the growth rate of the memory chip market. The giant growth of recent months, fueled by demand for AI solutions, gave way to the realization that current prices may have already priced in all future successes. The decline continued on the U.S. exchange as well: SK Hynix shares traded on Nasdaq under the ticker SKHY fell by 9% to $154, after soaring more than 14% on their debut day on Friday.
The Domino Effect: How SK Hynix Collapsed the Entire Market
The collapse of SK Hynix shares had a devastating impact on the entire South Korean stock market. The KOSPI index, where the company's weight is enormous, plunged by 8.95%, closing at 6806.93 points. The drop was so rapid that, for the first time in a long while, a circuit breaker mechanism was triggered during trading, temporarily halting trades to curb panic sentiment.
This episode clearly demonstrates how vulnerable a market can be when its dynamics are driven by a single superstar. SK Hynix, being a heavyweight in the index, effectively became the trigger for a large-scale sell-off, dragging the entire market down with it.
Cryptalist Analysis: We are witnessing a classic "buy the rumor, sell the news" scenario. Investors who bought SK Hynix shares on the wave of AI hype are now hastily exiting their positions. The question is whether this is a temporary correction before a new rally or the beginning of a deeper downturn. Given that the fundamental indicators of the memory chip sector remain strong, I am inclined to view this as a healthy correction that will clear the market of "overheated" positions. However, the scale of the panic should not be underestimated — such movements can trigger a chain reaction.
