I would have thought...... that the NASDAQ would have had it under their IPO watch list, but there is no indication that it is on the exchange other than today's trading...
... I find it highly unusual that it would have traded without any forewarning, but maybe they could not give any indication (either the NASDAQ or Westport) because of the financing associated with the IPO...
... in any case, its up and running, and time will tell how things will shake out... personally, I'd kinda like to see the short traders load up, then have Westport release an NR stating that they are going to lease 6000 buses to Thailand (or something to that effect)...
