"the last patient was enrolled by Jan 7 and I have to assume that all the pertinent top line data is currently in the hands of GTCB"
Why do you have to assume that the data is in the hands of GTCB? The patients may have been recruited as of 1/7 but the question is when is their data available? The press release certainly suggests that their procedures were scheduled such that management expected the data to be available "around" the end of January, but I don't think the press release means that everything was done as of 1/7, only that it was expected to be done in January. After the patient's procedure is finished, there is a period of observation (until the risk abates, as Dew has told us) and it is possible that that might slip a day or two.
If you really believe that management is sitting on the fully analyzed data, it seems to me that you have only one choice -- sell in the next 100 minutes or so.
