Sell your copper and Alu now! Or hold it for a while.

Not sure if my metal yard as dropped their prices, but the e-waste buyer has certainly sent out a notification saying prices may drop in the coming weeks as this whole mess plays out. I am currently planning on stockpiling my aluminum and copper, and just selling steel. Steel, like everyone else I'm sure, is what I get the most of so I can't stockpile it very easily. Anyone know if brass is going to be dramatically affected? I don't get much brass fast, but I was just asking to see if I should stockpile it too. Thanks!
