Highly encourage everyone to heed the advice in OP's last line.

Hedge your investments. Rather then dump 100k at once into SPY (SPX if not using your 401k) or similar. Invest 10k per week/month. Thousands of people way smarter than you and with 20-30 years of experience fail at timing the market. You will not be able to time the market. Hedge into your investments.

Or buy puts on spy/calls on VXX and hedge your downside in an uncertain market

Yes, but options trading is not for the average trader/faint of heart. You can easily lose your entire position if not timed correctly.
