So, with STR, you can account for growth at the individual stock level by increasing constant value, or at the portfolio level by adding positions with excess cash, or both.
Praveen,
One part of your "system" that I find most useful is the adaptability. I also like the simplicity of keeping positions at the same constant value, less work than some at this level, others at that level, and so on. As I'm still in the working world and adding cash, one could grow the lot to a new constant value by not taking some profit when you would normally, and use the added in cash to bring the laggards up to the new level, and go from there.
Best,
