Costco is one i've been watching. The close before the long weekend was ideal if you entered short once again underneath this yellow trendline.
An overshoot to 508-510 is still possibly in play and that's where i'd be looking to start a longer dated short position or even sell out of the position if we get to that target.
Costco is a very strong company don't get it wrong. This is a stock i'd buy in my retirement account at nearly all support lvls below 480.
