My retirement accounts have had a pretty big drawdown. This move was approximately -10% in 5ish days. Seemed like a fast ride up, but how about that drop!
You can really see all the trading axioms are wise:
Don't try to catch a falling knife.
The market can go down longer than you can stay solvent.
Hope is a 4 letter word.
Trade with a plan.
The market doesn't care what you think.
