A handful of people short could affect that number. Or the timing of the poll, combined with a general assessment on odds of a second CRL at that time. Wonder if that % would be different today?
This percentage is coming from a survey done regarding 10 pharma stocks, for 80+% of the people that posted a comment on that survey, regarding a majority of the companies, it was a coin flip without actually even spending time to read. They were most likely posting a positive outlook for whatever pharma stocks they were invested in and then didn't take the time to understand the others.
