Currently, the best strategy I personally believe in is to hold and observe, placing it into a money market fund. The probability of a significant decline is not very high, a drop of around 5-10% is enough. I don't think it will fall below 4000 points. It's okay to take protective measures, shorting doesn't make much sense. But since the downtrend hasn't stopped yet, I dare not rush in to buy, I can only wait boringly. In addition, it's also good to allocate some to defensive sectors. I will continue to hold medical, energy, agriculture, and defense stocks.
