Steady_T,
The market that is visible clearly is not the source of any massive naked short scheme and that is where I agree with the bears. Where things get more dicey is with dark pools, Sovereign Funds and other channels that are much more difficult to track. The question would be about where the mingling of markets might occur if any, with who and how. There are myriad ideas but laying out the proof that any idea has merit is extremely difficult. Some whistle blowers have shared a their pathway taken which could be traced back. There is much more potentially yet hidden but as of yet unprovable to the point necessary. Hence my hesitation to give traction to the idea of massive short selling even if I support full investigation of the potential for it. Best wishes.
