You are missing a critical part of the calculation and that is what $500 or so is worth. In this case it was worth losing it all versus gaining much. That is what you are missing.
A major repair on a car which is a wasting asset can cost north of $500 which would buy you 2000 shares and that was not the low.
Money should work and at these rates keeping it in a savings acocount where there's certainly is a losing, due to inflation, proposition.
If a sale is announced do you buy?
I consider you a sophist, nothing personal.
