That was weird as not finished post and off it went.

I was going to say that while 'greed' for profit can be dangerous we have to consider, if playing a number of companies, that not all will hit it big. One way to maximise profit is to hold on just a bit longer than comfortable with those that are stars and shoot up extremely high as the profit on those can cover the lack of profit on losers in the race. It's a fine line to walk.
