Wow. I can't believe I've made it into the top 20, after starting less than 3 months ago with a negative score. I confess, I got into the top 100 by copying the picks of anyone in the top 10, with no research on my own.
Since then, I've read a couple of the Motley Fools' investing books, studied the website daily, and decided that it was about time for me to start making my own picks. As TMFElderhad points out, you can't beat the people ahead of you just by copying what they're doing. So, as of January 18, I've been making my own picks -- and low and behold, my accuracy has gone way up! I should have trusted myself sooner.
Anyway, I shouldn't get cocky. I still have a LOT to learn. I finally bought some REAL stocks just last month and only 50% are doing well. :-( If only I had the money to buy all of my CAPS picks I might get somewhere!
