If you want to go back to May of 2013, just before the PPS collapsed in the wake of Assure missing its primary end point....okay.  You may not deal much with Technical Analysis, but I have studied it a lot.

Okay...after that failure the PPS tanked to down around 20 cents.  For your thesis of a downtrend continuing for the next 4+ years subsequent to that 'Black Swan Even', then the PPS (as you correctly note) would have had to continue making lower and lower lows.  But that didn't happen....never once did the PPS get down to that 20 cent area.  That drop post assure wasn't part of  a broader trend, it was...as I noted, a black swan event.  And since that time, from June around 20 cents, to present around $2 has been up.

But if you want to see the overall trend from before the Assure failure to present as down, disregarding the climb from 20 cents to $2, no worries....
