Common sense prevails and the planes are grounded. Opens up some interesting options trades on Boeing (BA) with implied volatility spiking.

I have started analysing Call Spread Risk Reversals over different expiries.

One has to believe that Boeing will resolve the problems - it will take some time as Ethiopia Airlines has sent flight data recorders for France for analysis - into the Airbus heartland. Weird that.

Timing is key. Earnings are in April - so smart to look at may expiries. I will write something up later today.
