Holding SK Hynix for a few months, the volatility has been unbearable. Sold off a large position just before the takeoff, missing it by a hair's breadth—should have waited for the earnings. I think the earnings were basically an open secret, why has it been so volatile? Switched to US stocks and US stock options, lost some on Microsoft, and the long call on Qualcomm was also entered too late, bought at a high point, and it's been volatile recently, held for two weeks. Bullish on the subsequent major cycle for CPUs, the demand for agent CPUs, and the constraints on TSMC's capacity. There aren't many CPU players, and the ARM architecture holds a significant advantage with multi-core performance and higher energy efficiency. The server ecosystem has developed and improved a lot over the years. The growth slope for server CPUs should be steeper, with both volume and price rising, bringing higher alpha returns to CPU manufacturers. Currently entering Qualcomm or a long call at this level isn't too high, very likely to profit. The current speculation still revolves around infrastructure suppliers, focusing on Intel, AMD, QCOM, and ARM.

Currently, policies are tightening, just go with the flow. Improving investment strategy and skill is the key, not complaining when you don't make money or lose it, or dissing and cursing when you lose by following someone's strategy—that's a childish mentality. There's a lot of negativity in society now. Of course, I believe the policy's starting point is definitely good, a result of weighing all aspects. The mindset for buying stocks should be to go with the flow, verifying your own understanding and getting results is the best. Here, there's only a small amount of capital, making or losing money, you still eat the same food and live the same life.
