Yeah. The RH investor in your example has definitely abandoned rational investing sentiment.
The difference, as I see it in my mind, is that the RH investor knows they can get hurt. In fact, they are probably assuming it as a foregone conclusion. But they choose to play anyway, because -- and here's the key -- what do they have to lose?
Now the hedge funds, they are taking the position we ought to pay patronage to them; they'll protect us little guys from the evil perturbations of the market, as long as we're OK (in the words of leon Cooperman) collecting our 2% a year and shutting the F up about it. The hedge fund guys -- masters of the universe -- not only think the retail investor doens't know what they are doing, they think they don't deserve a seat at the cot dang table!
This week could've been an awesome example of creative destruction. An enormous transfer of wealth would have occured, transparently and fairly, between the gilded gentry to retail; it wouldv'e been the kind of week that was celebrated in its magnitude for a long, long time. But, while it's OK for John Paulson types to bet big and make billions on the housing bust w/ Goldman's Synthetic CDO abacus (at the expense of retail!), it's not OK for retail investors to repeatedly land haymakers to the face when the tables are turned.
It's unjust. Nobody likes a rigged game.
