SK Hynix shares suffered their steepest single-day decline in the company's history on Tuesday, as traders aggressively took profits following the memory chip giant's recent debut on the Nasdaq.

The sharp sell-off marks a significant reversal of sentiment, with investors growing increasingly cautious about the speed at which the company can translate artificial intelligence tailwinds into sustained earnings growth.

This development follows a period of heightened activity for SK Hynix, which had seen its shares in Seoul drop more than 10% earlier in the week, wiping out much of the bullish momentum generated by the US market entry.

The price action underscores a broader market recalibration regarding AI-related equities.

While the Nasdaq listing was initially viewed as a major liquidity and prestige boost for the South Korean firm, the immediate aftermath has been characterized by volatility rather than sustained upward momentum.

Traders appear to be prioritizing near-term valuation metrics over long-term strategic positioning, leading to a rapid erosion of the post-listing premium.
