While last week's relentless panic buying has been extensively commented on, it was last week's nearly 50% plunge in near-term stock vol that the major news as the world went from risk off mode to risk on. It wasn't just stocks whose volatility imploded: it was the implied near-term volatility of all asset classes that was hammered in the past three days. But while everyone is fascinated by the rapid VIX down move, it is what someone did on Friday by betting that VIX will double by February in a 24/29 VIX Call Spread, that was of note. The amount wagered: $6.7 million. Whether or not this was an outright trade, or a hedge (and if one listens to Jamie Dimon perjuring himself to Congress, any trade is a hedge, adding further to the confusion) is unknown, but it is not pocket change betting that the plunge in vol will be merely transitory.
