"A public corporation couldn't cancel their existing stock, in order to reset the price at a fair valuation."
Hmm. Isn't the "valuation" set by analysts and investors? I mean - if it suddenly becomes worth more - people buy it and the price goes up to what the public feels it's worth. Like Google.
The trouble is, what the public thinks (not Rufus) is what will ultimately set the price. Why not just let the market take care of it for him?
Good stocks are obvious. Extensive DD is how you convince yourself to buy a bad one.
