To be material would imply a rational investor would factor the information (which is who is standing next to the poster) into a buy/sell decision. I seriously doubt anybody here would say Yopp's presence is that significant. I actually doubt the poster itself is material (as I assume it will not have much more data than the abstract).
Hell, a Vegas showgirl next to the poster might work better :-)
I am not often confused but I will agree that I am a little with the latest discoveries about Doctor Yopp.
1) he is indeed listed as the presenter for today. 2) he is indeed listed as the moderator of another event today 3) both are many miles appart, so not sure if plain/time-zone me explain it
Anyway, if Doctor Yopp does NOT present the poster himself then do NOT expect any peace of detail you do not already know from previous communications or from the abstract or possible PR if any today.
For Doctor Yopp moving the needle 24+% with a clinical trial Sorafenib+Bavituximab that is going to put him on the map. As I explained here 24+% in Liver is HUGE. It will be remembered.
No way Doctor Yopp is going to send one of his assistants (he is himself an ASSISTANT Professor). So either the professor that he assists shows up or some other team member, or someone of PPHM replaces him. BUT AGAIN, this is IMPORTANT and SUCCESSFUL work and he will want to be in the spotlight when the real hard news is given out.
So, assuming the second event isn't a hoax (because in this world we've seen complete web-sites set-up and referenced to fool people or to give credit to fake doctors and facts etc, then there is a 50/50 change Yopp will present the poster. The people from the event will be saying exactly the same thing as we do: Yopp presents a poster, how can he moderate at the same time.
What we have in our advantage is that he was not the ONLY moderator and he could probably be better missed there then here. Leaving his name as moderator may have been a trick too to keep peoples attention and then last minute say : Sorry but Dr Yopp had to give a poster presentation at a conference and excused himself.
IR probably knows the answer and they can comment because they have the event on their web-site and CK always comments on information that has been disclosed officially. Anyway for no no trace of Yopp.
