Add the winners

The only way to be profitable?

 

lmfao

 

Or rebalance portfolio once a year.

 

Do you mean add TO winners? That is actually probably the only thing that works.

 

and minus the losers.

Or

Multiply the winners and divide the losers.

And those are the only 2 ways to be profitable.

 

Multiply the winners and divide the losers? I do not understand

 

Which of the two ways do you think is better?

 

%%
Sounds like you understand/ add to winners;
divide losers= cut a loss\ partial loss+ sometimes that work$ to profit . Cut the rest of the loss if it does not turn profitable. Tends to work well................................................................

 

Yes, you have solved it!!

 

In practice it is not so simple
