12/27/12 - I have been tracking JAJO, unfortunately it shows the same data as Jan 19 monthly. There is no difference. I imagine this year is fiscal cliff one-off related.
03/18/12 - No reason for a JAJO graph for April. The option landscape looks the same either way I graph it. I will keep track of it and if something comes up will let you know.
This is the OI that has been added or removed from the Jan'12 options since December became the front month. I will update this chart on Sundays. When Jan'12 becomes the front month I may start an additional graph showing only front month accumulation/dissipation.
What is JAJO Pain?
AAPL is on a January, April, July, October option cycle. When options are left on the board for 2 years at a time the OI can become less relvant. An example would be Jan'12 options. These first traded in 2009. What are the option writers real cost basis? Have they already made a huge profit?
In the 1-2 years that have passed, option writers may desire a totally new outcome only seen by clearing away those stale option positions. JAJO Pain will only show the positions that have accumulated since becoming a front month. This way we can see the whole picture and a more up to date one to make our decisions.
