re: Chris Camillo’s AMZN “all in”

I'm unsure what your point is. My points are that short-term, relatively speaking, outcomes are unreliable for determining long-term results and that mistakes are still mistakes even when you don't get consistently punished for them. These points are why risk management is so important.

Finding a trading edge isn't particularly difficult to do. The real value in trading is creating a system to survive when things don't work out and being able to follow that system. Obviously I don't have the information to know if Camillo has such a system in place, but getting multiple margin calls only to double down implies he either doesn't or doesn't consistently follow it.
