Normally if a company’s stock falls upward of 50% in a single day, it indicates a catastrophe has happened. Bad news of biblical proportions. But such is not the case with EQT, the country’s largest natural gas producing company. EQT’s stock closed at $34.64 per share on Monday. By the end of Tuesday, it was $18.56, down 46.4%. Why? Because the company split in two, with EQT Corporation retaining all of the drilling assets, and a new company, Equitrans Midstream Corp., taking off with all of the midstream (pipeline) assets.
