I briefly exchanged e-mail with Professor Poteshman, and did a post on SLC on the paper earlier.

While I believe he is a serious academic and it is a pretty good paper, I still have some problems with it. Essentially he is saying that the trades (he only examines UAL and AMR) are in the 96th percentile in his way of measuring put option volume. Otherwise, it is in the top 4-5% of occurrence. Based on this he concludes it is likely the trades involved foreknowledge.
This of course cannot prove anything specific though, it could just be pure random chance, basically a 1 in 20 of occurrence. The biggest problem I had with the paper is he essentially self selects the data to read. He picks 3 measurements, but then discards one, because it didn't show a higher occurrence. Well, then he is basically cherry picking numbers that fit his hypothesis.
You will never see this paper mention among the CTs much, except for LIHOP, because his entire thesis is based opon Osama bin Laden knowing about the attacks 5 days beforehand, so he only looks at the trading on those two stocks during just this period. Obviously the Illuminati/NWO could have carried out a much more lucrative and harder to detect fraud over a longer period of time.
This brings up another issue I had with the paper, he only measures the maximum trade volume during that 5 day period. I asked him in e-mail, why he didn't measure the average volume over that period instead. He answered that because it didn't show anything. Once again, indicating he is cherry picking data to a certain extent.
