yes, I agree. Avanir being a recent example of a massive bear trap just before positive news. How disappointing for the longs who were stopped out just before the pps doubled. However, I dont share your cynicism regarding the potential for leakage of the results here. As you know it will be months before the results are fully analyzed and then the results will be tabulated and released shortly thereafter. I think this process is clean until perhaps the very end when a few people are in a position to benefit. I dont think changes in the pps weeks or months ahead of the release of the data are indicative of anything except the normal trading patterns and then, as you said, a possible bear trap ahead of what will hopefully be positive news. Obviously the wise thing to do here is not to employ a stop loss, because it is very likely that this scenario will also play out here.
