1/28/16 was up +0.88 to 66.50. Each time the component moves up, traders push the GGGs up and the "Gap" doesn't get closed much. Right now it is 4.35 with the GGGs being premium over the futures.
The six-day moving average carcass weight was nearly unchanged today with the Index hogs being the lightest weight of the various categories that I track.
Scalping in and out of the GGGs has worked for me this morning and have been quite busy loading and unloading all sorts of spreads. More had gone off than I have been able to take on so my boat is a bit high is the water and my bank account is a little fatter.
Best wishes,
