Before discussing anything else, let me start with a simple question about the memory sector. From their recent highs to where they are now, stocks such as [$SK hynix (SKHY)$](https://ttm.financial/S/SKHY) and [$SanDisk (SNDK)$](https://ttm.financial/S/SNDK) have fallen sharply in less than two weeks. Have HBM orders declined during this period? Have NAND flash and DRAM prices fallen? Clearly, the answer is no. This suggests that the fundamentals have not changed. What we are seeing is simply a short-term leverage unwind. Below is my detailed analysis and personal view based on the available data. First: SK hynix’s fundamentals have not been disproven, but the short-term bottom has not been confirmed SK hynix’s Korean-listed shares plunged by more than 15% at one point today. The KOSPI fel

Following up on my previous article about my outlook for the memory sector in July: Fourth: Being Bullish on SK Hynix Does Not Mean You Should Hold 7709 Indefinitely [You may be able to wait with [$SK Hynix (SKHY)$](https://ttm.financial/S/SKHY) shares—but [$CSOP SK Hynix 2x Long (07709)$](https://ttm.financial/S/07709) may never make it back to its previous high.] This is one of the issues investors most commonly misunderstand. Being bullish on a company and choosing the right instrument to invest in it are two entirely different things. If you own SK Hynix shares, then as long as the company’s profitability and competitive position have not been permanently damaged, you can theoretically wait for the next upcycle. Leveraged products such as 7709 are different. They are subject to daily r

Bernstein just released what I think is one of the most important research notes on the memory industry this year. $纳指100ETF(QQQ)$ $闪迪(SNDK)$ Most headlines focused on one number: A Bull Case valuation of $4,400 for SanDisk. But in my opinion, that's not the real takeaway. The report spends far more time explaining why this memory cycle may be fundamentally different from every cycle before it. A year ago, when SanDisk was trading a fraction of today's valuation and most investors still viewed NAND as a deeply cyclical commodity business, Bernstein was one of the very first firms on Wall Street to publish a $1,000 price target. Back then, many thought it was far too aggressive. Looking back, they were simp

If I had to summarize my first half of 2026 in one sentence, I would say: It was a first half filled with both pain and reward. The reward was that I saw the opportunity in the memory sector early. The pain was that I got the direction right, but I did not truly hold on. The best decision I made in the first half of the year was starting to build a position in the memory sector in January, mainly through Micron. My thinking at the time was simple: As HBM prices continued to rise, DRAM and NAND were also entering a new pricing upcycle. The memory industry was likely moving back into a strong cycle. Historically, memory has always been a classic cyclical industry. Every few years, it enters a powerful upcycle. But this time is different. This cycle is not only driven by a normal supply-deman

Market Structure View on $SKHY The key point is simple: A 7x oversubscribed book proves that the primary market wants allocation. It does not prove that the secondary market has to keep bidding the stock higher. The real issue here is that the primary market and the secondary market are trading two completely different things. SK Hynix’s U.S. listing is huge. The basic facts are clear: 17.79 million new common shares. 177.9 million ADSs. 10 ADSs represent 1 common share. Demand reportedly exceeded available supply by more than 7x. Large U.S. institutional orders started around $200 million. Baillie Gifford, Coatue, Situational Awareness and other major funds have shown interest. That demand is real. But primary demand and secondary price action are not the same thing. The primary market is
