Market is abit crazy now so I would watch for abit. But generally, I have my eye on a few such as Etsy, Adobe, Nvidia. I wouldn't be able to catch the exact bottom but personally I feel that these are now at good enough price for me already.
I would generally try not to follow Cathie Wood's moves cause looking at her 2021 trades, I feel she just got lucky in 2020. But I agree that Shopify is one that is good for long term investment.
This year's Nov and Dec movement seems abnormal but good time to pick up or add more position in some good growth stocks anyway. Otherwise, just DCA and we'll be fine!
Nobody can time the market but take heart that the stock market always goes up in the long term. If u r an investor, u shldn't be too worried abt short term fluctuations.
