I bought AAPL at 175, NVDA at 290, MSFT at 329, GOOGL at 2900, META at 336, NFLX at 590. Should I sell them and just buy SPY/VOO/VT?

I went heavy into the ARKK and high flier tech stocks that were popular in Jan-Feb 2021. You probably know the names if you browsed reddit in that time some of them were SHOP, NET, PLTR, SQ, and SOFI. Lost 60% of my capital on those. And decided to sell all of them on the last trading day of 2021. And buy big tech stocks on the first day of 2022. It turns out that was the top for those stocks.

And now I feel like giving up on individual stocks all together and buying index funds now. My next plan is to sell all my big tech and dump my left over capital into index funds the last week of July. Is that best or should I continue to ride out big tech?
