Every day is hitting new highs, it's just rising too fast. I didn't buy enough positions, but it's still okay.

My U.S. stock account strategy is that even if I really like individual stocks, I can't exceed 10% position size; I'm only short by 2%.
I operate with two accounts. One is Interactive Brokers, which is my long-term account where I don't do short-term trading; the other is Futu Securities, which I use only for short-term trading.
My long-term account allocates 50% of positions to index investing through regular contributions, and the remaining 50% is used to buy 5-10 individual stocks I like. If there are no stocks I like, I don't buy yet.
My short-term account is with Futu Securities. I've bought two individual stocks so far. One is CRCL, which I've already sold (very small position, made enough for a meal), and one is RKLB (large position and I keep adding to it). When favorable news for the commercial space sector materializes, I'll cash out my principal, then transfer all remaining RKLB profits to Interactive Brokers to convert it into a long-term RKLB holding. It doesn't matter anyway since it's all profit.
Going forward, I want to ensure that whenever my short-term positions make money, I withdraw the principal and some profits, then transfer the remaining positions into long-term holdings. By the time I'm 40, I'm not sure if I can accumulate 30-50 individual stocks with zero cost basis, but if these stocks keep rising, I'll gradually liquidate them and add to my index positions.
