At times like these I start with just buying about 1/10 of the position I'm comfortable owning and will add a little more if it goes down each 10%. So around $180 and again $160 depending on how fast it falls. I can't time the the market and there seems to be a running for the exit sale getting ready to happen. Have cash on the sideline waiting for SP 500 to break 4,000. Might go as low as 3600 but the trick is to buy a little at a time and be willing to wait at least 3 years. But you can't use this theory when buying high risk stocks. They must be watched and protected.

Worse trade I made this past year was not buying the SARK etf when I knew about it and passed when it first opened. It shorts the ARK etf. Only up 93.4% since it opened Nov. 2021.
