However, the steel makers themselves aren’t seeing the fruits of this higher demand and prices. Iron ore prices are up sharply, with most ore producers raising prices by 23%. This has caused the margins and gross profits for major steelmakers to fall. For example, Steel Dynamics (Nasdaq:STLD) recently issued an earnings warning, saying that second-quarter earnings per share would be around 22 cents per share lower than Wall Street estimates. With production and rising costs, many of the steel producers have seen their share prices fall hard over the past few weeks.
