if you really believe thats' all costco does, clearly you have no clue what you are doing....Do not expect too much from COST when its P/E is over 27 and the only thing that it does is selling packs of 100 canned food or pack of 200 toilet paper rolls. $157.5 is the right price.
I agree and I will be stubborn as long as they stay irrational. I sold 157.5 PUT double my short position expiring tomorrow for 0.62 so while I am waiting, I am also making money (reducing the loss). I was long on COST when it dropped to 156 after earnings and then I sold at 161. The trick is that if you can or plan to short 1000 shares, just short 200 now and wait and have the right ammunition to short more and correct your trades with options.Most companies are highly overvalued at this time. Market will stay irrational longer than you think.
