description: "$Intel(INTC.US)$Invesco Nasdaq 100 ETF(QQQM.US)$SPDR S&P 500(SPY.US)Here's a little personal advice for my friends.1. Don't be emotional. Emotions affect rationality. Investing is a rational game; its essence is seeking positive expected value.2. Don't short. Having a bubble doesn't mean it will fall. The bubble might be digested or might last for a long time. We want to make money from the bubble. Timing the market for shorting is very difficult.3. Don't stubbornly hold on when it falls. Look at: whether the logic has been disproven. Don't take profits immediately when it rises. Look at: whether the logic has been fully priced in. Don't make decisions based on relative price movements (up or down 30%, 40%). Also, don't make decisions based on your own cost price; price movements have nothing to do with your cost.4. Don't do day trading. Theoretically, it doesn't improve your mathematical profit expectation unless you can predict the short-term market, which I believe is impossible. Win rate isn't important; the key is profit expectation."
