Brand-name growth stocks ordinarily command the highest p/e ratios. Rising prices beget attention, and vice versa - but only to a point. Eventually their growth rate can diminish as results revert towards normal. Maybe not in all cases, but often enough to make a long-term bet. Bottom line: I wouldn't want to get caught in a rush for the exit, much less get left behind. Only when big growth stocks fall into the dumper from time to time am I inclined to pick them up - and even then, only in moderation.
