SK Hynix shares fell about nine% [1] on Monday during their second day of trading in U.S. markets.

The decline follows one of the largest share sales in history, signaling a volatile start for the South Korean memory-chip maker as it seeks to establish a permanent footprint on the Nasdaq. This volatility reflects a broader tension between the high demand for AI-driven memory chips and the immediate profit-taking behavior of institutional investors.

The company previously raised $26.5 billion [3] in what was the second-biggest share sale ever. That initial momentum carried the stock to a first-day gain of approximately 13% [2] on Friday. However, Monday's downturn wiped out a significant portion of those early gains.

Market analysts attribute the slide to a combination of profit-taking and a wider sell-off in technology stocks. The decline was not limited to the U.S. markets; shares listed in Seoul on the KOSPI also fell on Monday [1].

Reports on the exact magnitude of the drop vary. While Bloomberg reported a decline of about nine% [1], Yahoo Finance said the stock fell more than six% [2] on Monday. This discrepancy highlights the rapid fluctuations the stock experienced throughout the trading session.

SK Hynix remains a critical player in the global semiconductor supply chain, particularly as the primary provider of high-bandwidth memory used in artificial intelligence processors. Despite the second-day dip, the company's ability to raise billions in U.S. capital provides a substantial liquidity cushion for future expansion.

The sharp correction after a record-breaking debut suggests that while investor appetite for AI-related hardware remains high, the market may have overextended the stock's initial valuation. The simultaneous drop in Seoul and New York indicates a coordinated global sentiment shift, potentially signaling that the 'hype cycle' for memory-chip listings is entering a more critical phase of price discovery.
