It is quite early, but this should be on the radar for a potential shorting opportunity. If truly the beginning of a downward move, a further break of the around $72 would be a confirmation, and this should be expected within the next 2-4 months (pretty much from October - December, or even January). Also, the idea of the downtrend could potentially be a recovery for a possible uptrend if the resistance levels around $76 and $78 are tested and broken.
The financial sector was also showing some milder weakness but more time is needed to tell how the sector is behaving. Watch the energy sector; what do you guys think?
