Home Depot might be a good short. I know they'll probably drop on Earnings next week. Home building and buying going down (say what you want about HD NOT being in the business of selling houses, but im sure they will take a hit from the issue nonetheless), plus coupled with the tariffs, I definitely see HD dropping soon. 
  
 Calls and Puts lookin cheap too

I work at pgti window building and stuff seems to slowed down but still producing a lot of the cheaper metal windows like horizontal rollers although we have a lot less order for the premium vinyl ones. Still though the warehouse is over stocked since stuff can't be shipped out fast enough. You can probably count on a lot of home upgrades
