Where does the cash come from if you’re invested? Are you just keeping huge piles of cash around in low interest accounts in the hopes that a black swan event comes along?
If you had a balanced portfolio a week ago, you're almost certainly overweight bonds today. Rebalance to your target weights and you'll be buying equities.
Wow! Even with the crash, wouldn't you have been better off getting the last five years of gains, especially given interest rates didn't match inflation?
I was curious, so checked - $500,000 in VOO 5 years ago would have been 1.18 million today - already accounting for the crash so far. The market would need to crash an additional 60% starting with the next open to get you back to your $500,000 break even. Maybe this will happen, but that's quite a fall.
You make a personal evaluation that differs from the market and you act on it. You need a model of the world and to believe it is more accurate than the average. A lot of people felt the market was overvalued and would correct during the Trump presidency.
You of course sold all your stocks beginning of November because you knew a deep crash was coming and wanted to be ready to buy into it. And now you have a lot of cash.
