RE: helloA weakening USD (as its still regarded as the world currency) means that asset allocation are shifted towards hard assets such as copper, Nickel, Oil, Gold. As the USD goes down, the "price" for these commodities in USD terms is adjusted and goes up. Obviously because it takes more USD to buy the same amount of the commodity. What you often see because of a lower dollar, is a higher investment return from companies that trade based on hard assets as their value acts as a hedge agaist the currency. Gold versus the Euro has stayed constant but against the USD it has gone from $380 to $408. Gold companies that are unhedged have gone up as well because the price they sell their gold at in USD has increased. Given that most trade is still done in USD it stands to reason that a company like S will "get more USD" for their commodity they bring to market. It's not a perfect hedge but historically this is the case.
