Those who previously said that dollar-cost averaging in QQ was a good strategy at any time may not be right. However, at the current price, it's a good time to buy more; the price has fallen below the expected return for the past year. CRCL68 is clearly in the strike zone. You can buy TQQ spot to speculate on a rebound, and then switch back to QQ after making a profit. SPCX and TSLA face potential retaliation from the Democratic Party; 340 and 125 are quite cheap. Meta and Google have already fallen; I bought them before and after their earnings reports. If you don't have a position, now is a better time to buy. As for SOXL, I just want to wait for a chance to cut my losses; I don't dare to add to my position.
