Morgan Stanley Warns Chip Stocks Look Overbought Just as SK Hynix Debuts

Morgan Stanley chief US equity strategist Mike Wilson warned that semiconductor stocks are overbought, with the Philadelphia Semiconductor Index up 96% year-to-date and trading 35% above its 50-day moving average, the widest gap in nearly 25 years. The warning came as SK Hynix debuted on the Nasdaq with a $29 billion offering and Samsung posted a record quarter, yet Samsung shares fell 10% on the news, illustrating the overbought conditions Wilson described.

Morgan Stanley says the chip trade is starting to resemble silver right before it rolled over, and the timing is awkward. The warning landed the same week SK Hynix debuted on the Nasdaq and Samsung posted a record quarter. You've been reading two conflicting stories about semiconductors this month. One says the AI memory boom is the strongest it has been in a decade. The other, from Morgan Stanley chief US equity strategist Mike Wilson, says the rally has gotten ahead of itself. Both are true at once, and that tension is exactly what makes this moment worth watching. According to a note from Wilson's team reported by Bloomberg on July 6, the Philadelphia Semiconductor Index had climbed 96% year to date and was trading roughly 35% above its 50 day moving average heading into last week. Wilson said that gap was the widest in nearly 25 years. A nine day relative strength reading of 83 backed up the point. Earnings revision breadth for chip names had also reached about 70%, a level Wilson noted has only shown up three or four times in the last quarter century. Wilson's argument isn't that the AI buildout is fake. It's that Fed driven liquidity has been rotating through commodities, gold, silver, rare earths, and now semiconductors, and each leg of that rotation eventually peaks. He's telling clients the chip trade is closer to that peak than to a fresh launch. Frankly, that's a harder case to wave off than the usual valuation grumbling, because it's based on positioning data, not vibes. Wilson isn't calling for a crash. He described the pullback chips took in late June as a healthy reset rather than a sign that fundamentals are cracking, and he kept his year end S&P 500 target at 8,000. His team's actual call is a rotation, out of the most crowded chip names and into AI hyperscalers and other sectors that haven't run as hard. That's a narrower, more technical warning than the headlines suggest, and it matters for how seriously investors in Nvidia or Broadcom should take it. SK Hynix and Samsung Just Showed Why the Trade Got Crowded SK Hynix's Nasdaq listing this week is the clearest evidence for why chips got this hot in the first place. The company priced its American depositary receipts at $149 apiece, raising close to $29 billion in what CNBC and other outlets described as the largest first time share sale ever by a foreign company on a US exchange. The offering was more than seven times oversubscribed. SK Hynix makes the high bandwidth memory that goes into Nvidia's AI accelerators, and demand for that memory is the entire reason investors wanted in. Samsung's numbers tell a similar story, with a twist. The company guided to roughly 89.4 trillion won, about $58.44 billion, in second quarter operating profit, beating a consensus estimate near 87.3 trillion won and marking a nineteen fold jump from a year earlier. It was Samsung's third straight quarter of record profit. Citi Research pegged the drivers precisely: DRAM prices rose 44% quarter over quarter, NAND flash climbed 53%. And yet Samsung shares fell more than 10% in Seoul on the news, dragging the Kospi into a brief circuit breaker halt. A blockbuster quarter had already been priced in after the stock nearly doubled and a half over the year. That whipsaw, record earnings met with a sharp selloff, is close to a textbook illustration of what Wilson means by overbought. The memory supercycle isn't slowing down either way. China's CXMT is preparing to raise about $4.3 billion on Shanghai's STAR Market, the country's biggest listing since 2022, after first quarter revenue jumped 719% from a year earlier, according to Bloomberg. Subscriptions open July 13 and run through July 20. CXMT is a fraction of SK Hynix's size and still years behind on the most advanced processes, but its numbers show the same AI driven demand pulling capital toward memory chipmakers everywhere, not just in Korea. None of this means the AI capital expenditure cycle is ending. It means the easiest money in the trade may already be made. If Wilson is right, the next few months separate companies whose earnings can keep growing into their valuations from stocks that were simply carried up by a crowded trade. SK Hynix and CXMT are about to find out which one they are, in public, with real money attached.
