"What did JT's purchase of 20,000 shares on Tuesday signify? "
great question, and I see it as you do, that he is signaling to longs to sayyu long - but I also think its potentially a signal that good things are nearby
R-It confidence? maybe
Partnership? possibly
unexpected Arrangement with FDA - long shot
regardless, the insider buy by JT was a token event but IMO intended as a sign post - that is merely my opinion -
