I delete these.
I accidentally deleted a useful comment on the oil short-squeeze - but that was because it was bracketed by spam. To the author - I am sorry.
I have also received a wave of comments accusing all short-sellers of being criminals. I know that view is out there. But it is hardly constructive to repeat it here. So I deleted them (at least in part because of the aggressiveness of the commentary). However in fairness in keeping with this blogs policy of encouraging open comment I will at least tell you that the argument covers the full gamut of arguments against short-sellers and you can find them at the Sanity Check and other "anti-short-selling" websites.
My experience is that most people that argue against short sellers are in fact fraudsters - and they don't like that shortsellers profit from the falls in their stock. But I will listen to other arguments.
