I've been investing for a little while and my research has primarily focused on determining a strategy for stock picking. Now that I have that clear in my head, I would really like to have a more objective, simple way of comparing my performance against some benchmarks (probably the ASX200 and S&P 500).
I'm not a big fan of creating and maintaining complicated excel spreadsheets. Is there any software I can use where I can enter relevant info and it can do all the comparisons for me? How do others measure their performance?
