Alpha Metallurgical Resources (NYSE:AMR) +6.2% post-market Tuesday after it was selected for S&P SmallCap 600 index, effective before the opening of trading November 10.
The stock will replace Avid Technology, which is being acquired by Symphony Technology Group.
Alpha Metallurgical (AMR) had fallen 5.1% in Tuesday’s regular trading after Chinese customs data showed October coal imports fell 14.6% compared to September.
Lower domestic coal prices and higher overseas prices hit profits for importers, and coal demand in China was slowed by unseasonably warm weather for much of October and soaring power plant stocks.
Other coal companies also fell Tuesday, including Hallador Energy (HNRG) -12.1%, Warrior Met Coal (HCC) -5.8%, Arch Resources (ARCH) -5.6%, Ramaco Resources (METC) -4.2%, Alliance Resource Partners (ARLP) -4.2%, Peabody Energy (BTU) -3.6%, Consol Energy (CEIX) -3.5%.
