The government has injected a lot of money into the economy in the past months, weakening the US dollar. Commodity including coal, non-ferrous metals, steel, crude oil and agricultural products (especially fertilizers) and gold price have gone up sharply last month. This trend is very clear. What the government can do now except continuing printing money? US dollar is devaluating. Investors have to buy commodity-typed stocks or invest in commodity futures with their US dollars. That is why the commodity market and stock market rally lately.
