Yet he made 2 million when a million was a lot of money.Ah understood, Darvas said even less but at the time he didn't had the tools we have today.
You get to choose the size of your loss by sizing your position.My problem with having less stocks is that in case of failure the loss is bigger as the position size is higher. I don't want to buy and hold for years just get the momentum and compound when I can. I also want to trade more different setups from different screens and industries until "I feel" what works best...
What I do is size my position somewhere between 0.5 and 1% risk to my portfolio.
That is 1% of my portfolio divided by the difference between my entry and my stop = number of shares I buy.
With 1% portfolio risk per position and a 7% stop I can hold a maximum of 7 positions without using margin. (I rarely do) I will add to winning positions. I see no reason to close a position that is moving in my direction.
As price moves away from my entry I tend to give it more room before I exit
