SK Hynix $000660 Surges 30% as Hedge Fund Fire-Sale Ends

Sometimes the best trade is surviving someone else's disaster. That's exactly what happened this week when Situational Awareness, the $45 billion AI hedge fund run by a 25-year-old ex-OpenAI researcher, cratered to roughly $10 billion after margin calls on heavily leveraged AI bets forced a mass liquidation. Citadel stepped in, bought the bulk of the portfolio at a discount, and the market did what markets do: it ripped.

SK Hynix surged nearly 30% and Samsung gained 25% as the forced selling overhang cleared. South Korea's KOSPI posted a record 17% single-session gain, one of the most violent sentiment reversals in recent memory. Bloomberg's Daybreak Asia coverage flagged that JP Morgan and Goldman Sachs both signaled the broader hedge fund deleveraging cycle is close to finished, which is exactly the kind of all-clear that sends short-sellers running for cover.

YouTube finance is split on what this actually means. Bloomberg Podcasts' Daybreak crew framed it as a healthy flush: strong hyperscaler earnings from Amazon (AWS up 37%) and Microsoft (cloud growth fastest in four years) confirm the AI buildout thesis is structurally intact. The bull case is straightforward. Hyperscalers are raising capex guidance aggressively, with an estimated $10-12 trillion in cumulative AI infrastructure spend projected through 2030, and memory chips sit right in the middle of that supply chain.

The bear case is also worth hearing. Bloomberg's Merryn Talks Money pointed out that South Korea's KOSPI had already surged 35% for the year before crashing 34% in a single month, driven largely by leveraged retail ETF buyers piling in. China's rapid AI progress, including cheaper language models and domestic memory chip advances, is a real threat to the pricing power of Korean chipmakers. When your biggest bull case is that a forced seller is finally done selling, that's not exactly a Warren Buffett moat story.

On X, sentiment around $MU (Micron) is particularly wild. The stock swung 18% up after a similar-sized drop the prior day, with posts calling it everything from the trade of the decade to a volatility trap. The Bloomberg Daybreak Asia team noted MU was one of the top three holdings in the Situational Awareness blowup, which explains the whipsaw perfectly.

The SK Group chairman making his first-ever direct share purchase in SK Hynix is the kind of insider signal that turns heads, and it should. When the person with the most information about a company's future decides now is the time to personally buy stock, retail investors tend to notice. Whether this week's move is a durable re-rating or just a relief rally dressed up as a bull market, the chips are back on the table.
