Came across this concept recently and though I'd give it a try myself. BA has been good if you knew when to sell but a hell of a hold on stock and options October and further out as of late. Chart is from Early June to current date. I would prefer the Spring to happen earlier, however, given market sentiments this concept seems to be on point for how BA will play out up to earnings. I approached this as honestly as possible, but will try and take a smaller date sample and compare.
