Like a friend told me. He is 87 years old. This is much more safe to do. Nobody can short the market consistently and all the time. He got lucky a few times, sure but we are entering uncharted territory with the current market bull run.
Also, in the markets, the only way to make gains is to be inconsistent. If you are famous for shorting then people will be expecting shorting. You make sure people fall for it after you have done it a few times and wrote books about it.
So really, all your position is saying is "Do the thing he is a famous for and shills in his book". This is your "ultimate knowledge"?
That's like getting prepared to get slaughtered. Knowing that Soros is 'famous for shorting' is level 101. Everybody knows this. Your kind of logic is rather the popular one. Not mine
