Thanks for that link. I haven't tried it yet but I've seen the presentation before. It is well worth the time spent. The old link I had stopped working.

The technique of placing shares for sale at an unlikely sale price can limit legitimate shorting because it ties up the shares.

Naked shorting is insidious because the shares aren't borrowed but they are sold into the market as if borrowed and a failure to deliver notice is generated. That is how the stock is in effect counterfeited and more shares exist in the market than the company ever issued. Clearing it up is in the hands of the regulators and they have been so lax that the practice has become pervasive. So pervasive in fact that they have grandfathered in much of the deceit from the past because they know the chaos they would cause if they tried to make things right.

Another reason, along with many others for getting stock certificates from your broker for all your major (long term vs. tradeable) holdings.
