Doesn't your viewpoint stink of paternalism and judgement? You've assured yourself the price was too high. How are stocks priced? Based on how much demand there is compared to supply. So it's almost entirely based on future expectations. People are allowed to have different future expectations than you.
I've seen a TON of older people explain to younger people that the stock will decrease. This assumption is dangerous and shows a huge bias between age groups. I would not be so sure one group is more informed than another, but one certainly tells itself a story that falls in line with what the insiders want.
