[Sign up for First Trade](https://www.businessinsider.com/subscription/newsletter/first-trade), Business Insider's daily markets newsletter. Things have been changing quickly in the US lately. The American soccer team went from national heroes to World Cup donkeys after some [controversial presidential meddling](https://www.nytimes.com/2026/07/05/us/politics/trump-fifa-balogun-world-cup.html) and a [lifeless performance against Belgium](https://affiliate.insider.com/?h=feb0c5dc424187ed75df8fe6f2541f945032cc5ba46d5198190fbcd3ee019a35&postID=6a4e9bc5f38dd8af496120e0&postSlug=ai-memory-chip-stocks-samsung-skhynix-dram-etf-bear-market-2026-7&tags=service%3Acapi&u=https%3A%2F%2Fwww.espn.com%2Fsoccer%2Fmatch%2F_%2FgameId%2F760507%2Fbelgium-united-states). The Iran war ceasefire went from foregone conclusion to [uneasy standoff](https://markets.businessinsider.com/news/commodities/oil-wti-brent-crude-price-us-iran-war-trump-ceasefire-2026-7). The same has been true in the AI trade. After a prolonged period of outperformance for memory stocks and chipmakers — especially relative to hyperscalers like Microsoft and Meta — that dynamic is rapidly reversing. The [comeuppance for the memory trade](https://www.businessinsider.com/memory-stocks-bear-market-ai-sk-hynix-sndk-mu-wdc-2026-7) has been so swift, in fact, that as of Wednesday's close, many of its major players sat in bear-market territory, down more than 20% from recent highs. Let's quickly take stock: - South Korea's Kospi index: -20% - Roundhill Memory ETF: -23% - Samsung: -27% - SK Hynix: -32% - Sandisk: -26% - Micron: -22% To be fair, each of the individual stocks listed above are still up triple-digit percentages in 2026, while the Kospi is hanging tough with a roughly 70% year-to-date gain. But the speed of the reversal has investors wondering if this is the start of a deeper slide to come. Here's what's been weighing on the space: ### An AI company's best isn't always enough Samsung — and, by extension, the rest of the memory-chip sector — [found this out the hard way](https://www.businessinsider.com/stock-market-today-chips-selloff-samsung-micron-intel-marvell-amd-2026-7) this week. Record profit and a blistering growth forecast weren't enough to win over investors, who dumped shares in what amounted to a "sell the news" event. Worries remain that companies are overspending on the AI buildout. The episode secondarily highlighted the US market's [growing sensitivity to Korean chipmakers](https://www.businessinsider.com/korean-chipmaker-stock-selloff-samsung-sk-hynix-global-market-weakness-2026-6), which, after a torrid start to 2026, have experienced some hiccups in recent weeks. That sensitivity will be tested anew on Friday, when [SK Hynix](https://www.businessinsider.com/kospi-sk-hynix-stock-price-adr-listing-samsung-chip-stocks-2026-7) begins trading on the Nasdaq following a record-breaking US ADR listing. ### Geopolitical tensions are flaring President Trump's latest calling-off of the US-Iran ceasefire exacerbated nerves around the AI trade. Traders have been pricing in a resolution — and [looking favorably upon sinking oil prices](https://www.businessinsider.com/crude-oil-price-iran-war-impact-levels-supply-shock-trump-2026-7) — for weeks. If the conflict is prolonged, and inflationary worries start to creep back into investor psyches, the hottest parts of the AI trade could slide further. ### A rotational snap back As stock returns for AI hyperscalers fell behind memory-chip makers, a growing chorus of Wall Street strategists started calling for a [reversion of the trend](https://www.businessinsider.com/magnificent-seven-stocks-buy-the-dip-meta-msft-amzn-goog-2026-7). Mike Wilson, the CIO and chief US equity strategist at Morgan Stanley, was prescient with his Monday call for a chipmaker correction, and predicts a rotation back to hyperscalers. This conviction is [shared by Ben Snider](https://www.businessinsider.com/ai-stocks-investing-ideas-bubble-valuations-ben-snider-goldman-sachs-2026-7), his counterpart at Goldman Sachs. All rotation arguments circle back to the same factor: valuations. As chipmakers test the upper bounds, some hyperscalers are looking downright cheap.
