By my calculation, if you bought GOOG, AAPL, TSLA and NVDA at the perfect time over last 20 years, this is how much return you would have got.

Google: 2004 $2.55 Buy , 2007 $13 Sold = 5.1x return

Apple: 2007 $5.13 Buy , 2020 $79.68 Sold = 15.5x return

Tesla: 2020 $43.37 Buy, 2021 $381 Sold = 8.78x return

Nvdia: 2022 $13.83 Buy, 2026 $183.18 Sold = 13.24x return

5.1 x 15.5 x 8.78 x 13.24 = 9189x return, that's 918,900% !
For reference, NVDA over that same period is 1665x and AAPL 405x return
