This is not my find. @Eugene Voutchkov drew my attention to it. It's been in a range for about 2.5 years and currently is at the lower boundary. I sold a put.
EW is another (along with DXCM) covered call candidate on my list. I am not sure why calls are expensive. Last Friday one could get $2 for an ITM call two weeks out. They report Feb 4, and if ER is good, stock should continue climbing back to ~ $84.
I do not know if anyone besides @Rong Zhou had it. A nice chart. Very expensive options to sell. Report this week. I am considering if it does not drop or jump up too much.
