I wonder how many people, when encountering a big drop, just hold on stubbornly, and when seeing a small gain, run away immediately, strictly adhering to the investment philosophy of not taking a single cent from the market, and standing the last watch for the market! Admirable!

Summary: For rebounds after a sustained sharp decline, try to avoid day trading. Compared to other times, it's easier to miss the rally ("T fly") at this point! Some people might argue that they sold and then it dropped. That happens sometimes, but I'm talking about probability, not absolutes. The probability of going up is definitely greater than going down!
