- Revisiting the Ticking Time Bomb: “When is the Crash Going to Happen?”
by MARK SPITZNAGEL, http://www.pionline.com/
Since the question “when is the crash going to happen?” is always asked, we thought it particularly timely to update the research we have done on the topic. Timing a crash can be a fool’s errand, and fortunately such efforts are largely irrelevant if you are tail hedging (though they are quite relevant if you aren’t). When tail hedging efficiently, the extreme asymmetries in payoffs, by definition, removes any need to time the top. But this doesn’t mean that exercises in timing are without merit.
As we showed in previous research, without a doubt (or at least with over 99% confidence), bad things happen with increasing expectation when conditioning on higher Q ratios ex ante. That is, when Q is high, large stock market losses are no longer a tail event but become an expected event. Factoring time into the equation, and again based on history, the confidence interval around the median time would point to an expectation that the crash should commence right about now.
