Three hundred odd years ago, Sir Isaac Newton told us that “no great discovery was ever made without a bold guess.” My sense is he didn’t have the order book in Emini futures in mind, but his words do translate well to our world of financial instruments. In this short pod, I revisit the events of August 5th, a day when prices normally well discovered went dark. The implications are real and we ought to learn from this short-lived but real episode of instability. As we approach the “4 E’s” – employment, earnings, the election and the easing cycle – there’s a good deal to consider with respect to playing defense in markets.  I hope you find this interesting and useful.
