#美股市场波动 Seeing Nvidia's stock price fluctuate so dramatically these past two days is really nerve-wracking. Although short-term volatility is inevitable, we still need to stay rational and keep a long-term perspective. The investment market always has its ups and downs; the key is to manage your position sizes well and not let short-term swings affect your judgment. I suggest everyone develop a long-term asset allocation plan, diversify investments proportionally, and rebalance regularly. This way, you can spread out risk and achieve stable returns even during volatility. Remember, investing is a marathon, not a sprint. Stay patient and calm, and you'll go further.
