I have been shorting WPRT since the $40's and just covered my last OTM options recently. DEEP IN THE MONEY.
Natural gas as a motor fuel is at best a small niche business, and it was the "true believers" who drove this to $50 on hype.
If CLNE and WPRT can right-size quickly enough then they will survive within the niche at $1.00 / share.
A municipal contract here and a "study" there will only amount to slow organic growth... not the place to be looking to get rich quick or for a home run.
