Metal and mining stocks have plunged in recent weeks as the prices of commodities sink in the face of a strengthening U.S. dollar, as measured by the SPDR S&P Metals and Mining ETF (XME). Since the start of June, the ETF has dropped by more than 17%, and some stocks within that ETF have had even steeper declines. 

Mining companies Coeur Mining, Inc. (CDE), Cleveland-Cliffs Inc. (CLF), Freeport-McMoran Inc. (FCX), Rio Tinto PLC (RIO) and BHP Billiton Ltd. (BHP) have already seen their stocks fall dramatically, by as much as 37% from their 2018 highs. Now, these stocks may drop by as much as an additional 13%.

Weak Technical Chart

Freeport McMoran's is nearly 32% off its 2018 high, and the technical chart suggests shares fall by an additional 13%. The stock has fallen below a critical level of technical support at $13.80, to its current price around $13.70. The next level of technical support does not come again until $11.85.

Additionally, volume levels for Freeport have recently been rising on days when the stock is trading lower, suggesting more sellers are getting involved. The relative strength index has hit oversold levels, below 30, but has yet to show signs to indicate a reversal of the downward trend. 

Slashing Estimates

Analysts have been slashing their earnings and revenue estimates for the company's upcoming third quarter over the past month. Earnings are forecast to be $0.44 per share, 20% lower than the previous forecast of $0.57. Revenue estimates are for $4.9 billion, about 3% lower than earlier estimates of $5.1 billion.

Some Will Fall Less

But not all stocks are facing as steep a decline as Freeport. BHP and Cleveland-Cliff's stocks have both fallen roughly 10% from their 2018 highs. But the technical charts suggest shares of BHP fall an additional 7%, to $43.50 from its current price of roughly $47. Meanwhile, the chart for Cleveland-Cliff indicates a further decline of 6% to $8.90, from its current price of roughly $9.85.

Should the dollar continue to strengthen, further pushing commodity prices lower, shares of the metal and mining stocks are likely to fall further. However, should that trend reverse, this group could see a sharp rally off its lows.
