Dear elitetraders, I've been pondering over this question for some time. Please give me your experienced feedback. Suppose I want to establish a position in Apple stock. X amount is full position to put into Apple. I prefer to add to winning positions. Assume Apple is on the way up and I have 3 trades to make on the way up. Which scenario is your preference? Scenario 1 - 1st trade -> 33.33% of X - 2nd trade -> 33.33% of X - 3rd trade -> 33.33% of X Scenario 2 - 1st trade -> 50% of X - 2nd trade -> 30% of X - 3rd trade -> 20% of X Scenario 2 - 1st trade -> 50% of X - 2nd trade -> 20% of X - 3rd trade -> 30% of X I chose scenario 1. The reasons are; - keep things simple - No confidence which particular trade will work. So, keep position size the same throughout. Scenario 2 and 3 are more risky because initial position is larger. Higher losses will result if the stock pick is bad. I plan to use the same method to accumulate all other stocks in the portfolio. How would elitetraders approach this position sizing problem? There is no right and wrong answer but I would like to hear your reasons behind your choice. I would also like to see if any of the experts here see anything wrong with my reasoning. Thank you.
