Like what you also mentioned, there is definitely some affiliation with Hospira, Inc. as per a previous/older PR where TRDX at one time had increased their client base by becoming a distributor for Hospira which is a global pharmaceutical wholesaler: http://finance.yahoo.com/news/TRDX-Reports-2010-Estimated-iw-266448235.html
Now, if what you suspect turns out to be true in that maybe there is some kind of a Marijuana (MMJ) connection that have manifested itself between these two companies of which have a direct relationship with one another, then such could prove to be very huge. Maybe that’s why all of the volume this past Friday in TRDX.
