I'm trying to think of a bigger one-fight stock drop than Wilder-Fury II. In the first fight Wilder showed what got him to that stage. He was lightly outboxed a la Fury-Klitschko and looked confident and gunning for the kill until the final minute when Fury pressed forward. I believe Wilder was a slight favorite in the rematch despite common consensus being that he was awarded a Drawbbery in the first fight. All said and done, he was neck and neck with the other two massively hyped HW's of a massively hyped division. The manner in which he was defeated was so brutal, shocking, and complete, that no one watching could ever imagine his stock being as high as it was. This was an Enron level stock meltdown. Everything the haters had been saying for 7 years was being shown, crystal clear, on the biggest stage for all to see. Joshua getting battered, beat up, and stopped by a fat and unprepared Andy Ruiz didn't even see as much of a drop in stock. What are some other MASSIVE one-fight stock drops?
