Very surprising significant rise in price.

I have to admit I'm a little confused. One of our buyers on this board just updated his prices with a drop of between 10 to 20 cents per pound for the higher grade boards. Just a few minutes ago I received a text from Weitsman that they are raising prices on all metals starting tomorrow. I always assumed the prices would rise and fall in tandem. Can anyone shed light on why board prices are dropping while scrap prices are rising?

I think the precious metals market and ferrous and nonferrous markets are independent of each other. Thats my 2 cents worth.
