"Buy when there's blood in the street. Especially if it's your own blood."
The market will fall quickly but will rise slowly. You'll have plenty of time to get in but don't be in a hurry. We haven't seen a bottom yet.
My advice and I've been in the market for 50 years....Buy the best stocks in their respective sectors and hang onto them. Or just buy into one of the growth ETFs that's loaded up with the FAANG stocks along with a couple of older stocks like JD, CMI, PCAR, and a couple of financials like C, BAC, GS, etc. Maybe take a chance on PLTR and NVDA, I've made over 1,000% on those in the past 3 years.
