net from sale of Jan $900 calls at $70 is $42 and the present Jan 2015 $900 calls is $80?
When this goes back to $900+, the net will still be $120.
The difference being the breakdown: the Jan 2014 trade close out will be taxable while the sale of the Jan 2015 will be a Tax Deferred cash loan..
Now,,,,i have recapped this many time a month as a lesson..
there are approximately 6.7 million shares in Jn 2014 trade and 1.6 million shares in Jan 2015 trade that sold these covered calls
