This seems to me to be the least complicated story on Wall Street
Huge demand for a commodity with very low supply and only getting lower. 85% of the a/c in the US depends on R22 and this percentage will remain high for many years.This together with many barriers to entry in the reclamation industry makes it easy to understand why and how HDSN earnings will increase. Investing in HDSN is not reinventing the wheel as the story is simple supply and demand.
Investors speculate in new technology and biotech everyday with billions of dollars but their still seems to be only a relatively small amount of interest in this uncomplicated situation which seems to me easy to understand!!!
