Why recycling is profitable, and why this company could be a superb "Buy"

I may be looking to get back into this stock after a large fall in share price

Some companies are very volatile and high-trading businesses, despite the fact that their businesses are very simple in their overall approach and operations. This is one of those. From trading at virtually 15-17x P/E for over 10 years, the company shot up to over 40-50x P/E in COVID-19 and ZIRP, only to move back down and then move back up. I bought in when the company became cheap very briefly, but I sold back out when the company, in my view, became too overvalued.

The company seems about to drop again towards the levels when I bought it - and as such, I thought it a good coverage here for us on Wolf Report.
