How about a summary table of all actionable recommendations from various contributors and the current status of the recommendations? If I give a specific advise to Long/Short XYZ, it would be good to see how it turns out in the future.
Innumerable articles get posted every day. In many cases, the contributor might want to give out specific Buy/Sell recommendations. It's hard for a reader to keep track of all such instances.
I propose that when a contributor submits an article, she be able to specify a specific actionable recommendation (if she desires to). SA should present a summary table of all such past recommendations and how they are faring now.
