If we get a 35 - 40% boost in pps when the shares are retired, then we should get a 55 - 60% pps reduction when the dividend is issued. However, as TC has pointed out, we will then have 2 shares for every one share, so the value in your account is about 1.3 - 1.5 times as much as the day before the dividend.

This assumes a rational market - which unfortunately, excludes the OTC. Who knows what will actually happen with the retirement announcement and then again on Oct 30. I figure to let it settle out over the following 3 months or so, then we'll have a better idea of how GNBT was treated (hopefully, on the Nasdaq which seems to be a bit more rational than the OTC).
