Apparently, as the kids like to say, my maths wasn’t working yesterday.
When I rolled the adjusted position (from Mar 41.50/42 strangle to Apr 40/46 strangle), I hadn’t calculated that I already had a small profit in the position. At that point I wouldn’t normally have rolled since that would have been a defensive move. Should have just closed it out yesterday. Got a few cents more profit today so I decided to close the whole thing out.
Bought to close $MU 4/18 40/46 strangle @ 3.53. Total premium taken in with rolls/adjustments was 3.91, so a .38 overall profit.
