The surface reasons for the U.S. stock market drop: - Google Gemini launched with a bang, outperforming its peers. So the market thinks, Google, if your TPU-trained model is this impressive, then what has OpenAI been doing with NVIDIA? Just a scam by Jensen Huang? AI bubble! - Samsung plans to expand DRAM production capacity, so the storage price hike logic is gone. Even though the new capacity won’t ship until the end of 2026, with AI demand unchanged, new capacity means the price hike logic is invalid. Micron and SanDisk, you're done for. The real reason for the U.S. stock market drop: it’s just gone up too much and needs a pullback. - SanDisk went up 113% in September and 77% in October. Even the strongest stocks need a correction. - NVIDIA has been rising almost every month since April, with only a slight dip in August. Wall Street hedge funds sitting on massive profits are cashing out for Christmas. They’re nitpicking earnings reports and making wild guesses about performance forecasts, but in reality, they’re just finding excuses to lock in profits. In my opinion, there’s no fundamental issue with the U.S. stock market. Keep holding with confidence. After the valuation bubble deflates, it’ll continue to climb steadily.
