When reading through the Horsehead-letter of Guy Spier I had to think of you, because more than once you wrote as an answer to my questions, that especially when the stock price goes down you have to ask yourself ‘what does the market know, that I don’t’. As we could read, Mr. Spier now officially added this point to his checklist, too 🙂
Thank you for sharing this!
The Horsehead/Zinc Story would be good material for Michael Lewis (The Big Short). Very interesting stuff.
