This morning, many of the leading coal stocks are trading lower at the start of the session. It is important to note that the coal sector remains in a confirmed downtrend. This sector has been extremely weak since topping out in April 2011. Many traders should remember, the Chinese slowdown has had a direct effect on this industry group. Last night, the highly followed Shanghai Index (China) made a fresh new three year low. This is just another negative for the coal stock sector.
