Based on the performance over the past decade, the Nasdaq 100 (QQQ) has indeed outperformed the S&P 500 tracking fund (VOO). Based on this backtest conclusion, using the Nasdaq 100 as the main position when constructing an investment portfolio is more convincing.

Of course, if you want to strengthen exposure to the technology and AI sectors, you can also consider ETFs that specifically track AI and tech stocks. But from the perspective of convenience and liquidity, allocating to the Nasdaq 100 can save a lot of effort—its products are mature enough, holdings are sufficiently transparent, and choosing it as a core allocation is more worry-free in the long run.
