I guess this is a bit different than the quadrants about which I was refering but still in the same vein. Dave looked at the life cycle of the company and overlayed it with a P/E valuation and then pointed to where the stocks could be played. I always thought AIM could work in almost any of the quadrants, but that different levels of Cash Reserve should be allocated for each. In quadrant I for instance, it might be best to never use "vealies" and let the cash reserve run as high as AIM would take it because of the very high P/Es and expectations. That way when the bubble pops we can ease that cash back in when the stock shifts even possibly to Q II.
My thought is that a company heads for Q III or QIV that it might be time to either shift it to a different level of our Investment Pyramid or eliminate it from our holdings completely.
