Reflective Essay — I Know Why I Didn’t Make Money from Hynix

Today afternoon, I studied Hynix’s past and present thoroughly, no longer shallowly saying it’s just a “storage block” or similar, but personally digging deep.
I realized that in 2023, the year of the company's biggest losses in history, it instead increased R&D investment against the trend and abandoned its main revenue source to shift toward high-end server DRAM. This decision, made during a period when analysts criticized it and the company was under high pressure, allowed it to be the first to realize significant commercial returns in the AI memory cycle of 2024-2026.
While Samsung and Micron were still working on HBM3, Hynix had already formed large-scale supply of HBM3E and was gradually establishing a commercial realization path with NVIDIA.
What is a barrier? How is a barrier formed? The early effort, accumulated data, and aggressive expansion of customer collaborations are territories pioneered by the first movers.
For example, Hynix’s deepest moat isn’t “whether it can produce HBM,” but whether it can achieve sufficiently high process yield. And the characteristic of a yield moat is: it’s a function of time, not money.
Process yield requires actual production data from several generations of products; it cannot be bought, only waited for. Samsung and Micron have been chasing this in recent years, but process databases cannot be bought—they can only be accumulated over time.
Therefore, Hynix holds a dominant share in NVIDIA’s HBM procurement as the world’s largest AI customer. The benefits of this ecosystem are: NVIDIA’s next-generation GPU design, HBM interface data, and capacity reservations are all centered around Hynix’s roadmap.
These two aspects—yield + major customers—form barriers that make it harder for latecomers to catch up and more difficult for NVIDIA to change its route.
So, when facing losses or adversity and wanting to turn things around, it’s crucial to make bold, deeper updates—though difficult, perhaps this allows earlier awareness and planning for the future than those in smooth profit situations.
Then, I want to say something else. In our investment market, indeed, assets that experience explosive growth appear from time to time—Crypto, precious metals, crude oil, US stocks…
But how to seize opportunities, and why I didn’t make money, I think this question requires honest and multi-angle self-reflection. It’s about identifying where I was missing in the process, because even being half a step away from “making money” results in zero.
Taking Hynix as an example, personally, I need:
1. Hong Kong cards, brokers, HKD/USD;
2. Deep understanding of the AI industry chain;
3. Seriously addressing the information gap mentioned by industry experts;
4. Finding ways to buy, since there’s no channel to buy Korean stocks—what are the alternative methods?
5. Overcoming the low morale during war impacts on financial markets, understanding the cyclical nature of war, and keeping focus without distraction;
6. Maintaining a clear mind, free of emotional clutter and daily trivialities—focused mental energy;
7. Buying, holding, heavy positions;
8. Exiting.
What seems like an easy path to wealth is actually zero if any step is missed.
Therefore, I realize that investing is a journey every day, a business where only when everything is in place can one enjoy the wind. But I still haven’t added risk control—this might be luck or another big topic.
I just discovered this in my early thirties, but anyone who still maintains risk awareness and cautious respect during personal super-profits and smooth sailing isn’t too timid. Usually, it’s those who have experienced painful losses or deep valleys that develop the wisdom to grow.
Otherwise, those who haven’t hit the wall only know rushing forward—fast and fierce—but when stumbling, they’re easily exhausted and unable to get up again.
So, stability through accumulation, more homework, and risk preparedness. On my personal path, there’s always an opportunity to discover hidden chances and seize them smoothly. Keep going!
