I've recently added to my position within QD, as further research has led me to believe the upside is 3 - 4x (not a ramp post). Based on my analysis, I believe a re-rate to an earnings multiple of 10 - 12 is a fair intrinsic value for QD, which will result in a ~$25 - $30 share price (at a MarketCap closer to ~7 - 8 billion USD).
Here's the full video analysis for those interested: Cheers!
