SPGP is obviously related to the emergence of "quality" funds, as distinct from "value."...

I had a peek. Seems to have some logic behind it. The performance has been good for a pretty long time, beating the S&P Equal Weight. Not proof of success, but at least a lack of proof of failure.

However, looking at the picks, it seems to me that they are looking very much at RECENT growth, perhaps too much. Delta Airlines, United Airlines, Royal Caribbean, GM, Lilly...they're on a tear now, but are not what I would call long term reliable. I would prefer to have my money in companies whose period of good growth is not THAT different from the length of time that they've been in their current line of business.

Lots of good picks, though. You could just buy them yourself. The whole list is published, with weights if you wanted them, and it's not the sort of thing you need (or even want) up to date info.
