There are always people shorting. I've done it (Blackberry). Even a 'good' stock will be shorted if a speculator thinks the share price has overshot. Those folks are quite valuable to a properly functioning securities market. If they "bash" a stock to push the price down, that is as illegal as a long "pumping" the stock. Ie, it's not. As for naked shorting, that is their broker's foul, not there's, and it is the SEC's job to enforce its laws. And my experience in investing has been that good companies and stocks go up in the long term, and that 99% of accusations of "naked shorting" are done out of sour-graping, ignorance, impatience, and other bad investing habits. You'll see it here, guarantee it. We're human.
