There are quite a few guys who could jump from gold to diamond, silver to gold, and a few that may end up being downgraded. I've created a list of upgrade and downgrade candidates that I personally use for my own investments and roster. I know it's late in the week and might be too late to invest in the obvious candidates but I've had a ton of success with update predictions in the past and even if you can't make profit off some of the popular guys, you'll find quite a few new investments for this week and possibly beyond.
This is the first (and maybe last) time I'll make this list totally accessible to anyone. I wanted to get this out to see how accurate I can be in what is shaping up to be one of the more interesting updates we may see all year.
Enjoy!
