It would seem logical on first look that inclusion in an index like this would lead to good things. My experience with other stocks suggests it doesn't mean a whole lot though. Company fundamentals are still more important (for the long term investor). Right now PRR is still a spec company. I wonder how many other coys in the index are also spec? That would be a very interesting and helpful insight into the usefulness of this listing IMO. Might look into that.

In the meantime, here is an interesting article from a well respected fund manager on the subject (albeit the S&P500 in the US):

"Deletions from the S&P 500 regularly outperform new additions"
