A few more points about QQQ: 1. QQQ's long-term average annualized return is only 10%. Entering during a bubble phase can lead to underperforming 10% for a long time, or even being stuck for over a decade. So, it’s not like you can always earn a steady 10% annualized return without timing the market. 2. Buying the dip during a bear market crash is the key window to significantly boost your portfolio's annualized return. 3. Entering at the March 2020 low has resulted in a current annualized return of 17.2%, 7% higher than the average. 4. Entering at the 2022 bear market bottom has already achieved a 22.8% annualized return, 12% higher than the average. 5. The best strategy to boost annualized returns: Buy the dip during a crash + add positions at the bottom.
