Great post Quantum. I think all we need to know about why SGR share price tanked is contained in this one paragraph:

“[There's] a point I try to drive home to investors…when someone is pitching you on a story and they say the outlook is great, their company is fantastic, you [need to] say, ‘Okay, I buy all that. [But] how much do you have invested in the company?…Are you taking a low salary?’…In the last six years you saw large salaries, large options, and small [CEO] investment…It contributes to [under performance], because you’re not thinking every day about your exposure in your own stock. That’s why in McEwen Mining I own 25% of the stock, and I don’t take a salary. I wanted to be in the position where I make money the same way that my shareholders do.”
