I am looking at the divergence in performance of the two "WAL" retail stocks, Walmart and Walgreens.
WMT has rebounded sharply from the two selloffs in 2018 while WBA has been in a sharp dive since late 2018. The two are about as far enough apart in performance to set up a trade to bring the two back together.
WBA reports earnings on the 27th in just 2 days, that could be a catalyst.
