Yes, that it surely is - but from the Wall Street side; shorting 140% of stock should've been caught by regulators as it's illegal and totally impossible for retail investors. I don't think it was missed by mistake, though. People rallying to make profit from their mistake is nothing wrong, just new - this is the first time the small boys (instead of other big boys - but you can just ping them on Bloomberg terminal and make a deal with them) were able to catch them and coordinate their capital (the same thing the Wall Street guys are doing together, just bigger scale). It won't happen again as long as the big boys play according to the rules.
