NSS creates counterfeit shares. More supply with the same demand creates a drop in price. Great for shorts, bad for longs. A/S and O/S remains the same, but the counterfeit shares are ultimately the problem as more shares are entered into the market. After the NSS is resolved, the damage is already done as pps then suffers long enough for the stock to get stuck in a new trading range. I haven't examined the MFI in conjunction with NSS as I have ChiOsc in combination with Wilders. I will give it closer examination though.
