Usually I'm not into producers, but when a fellow Seekingalpha contributor presents a monumental, very critical essay on a household name like First Majestic, and I immediately spot some irregularities, my own critical attitude makes me feel inclined to not let this one go without going to the bottom of it, and look for a possible rebuttal in an attempt to provide a slightly more balanced view. It took me over a week to work things out, and the endresult hopefully shows you that skilled analysts like Kerrisdale need a closer look than others, but nevertheless their bias in their numbers can be revealed, and things don't seem to be as bad as implied in my view. It's a big read, still shorter than the original shorting report:
