Apple reported that the virus will negatively affect their sale and supply chain for the first quarter. That is not really a surprise, but it does have the index futures down about 1/2 a percent right now.
Gap up at 3385ish that will fill at some point. Bulls will want to try to hold 3347. A failure of that might bring a quick flush to 3330.
This is short the pops until 3383 is taken. Watch for a possible run to the mid as we get closer to the US open.
Have put a stop on that swing at +5
