Oil and Gas Stock Roundup: Bad Earnings and Terrible Outlook Unleashed the Bears

Earnings season was in full force this week as several energy companies reported second-quarter results and provided updates on what to expect for the back half of the year. That said, not all those reports were positive, which caused the market to punish the offending parties.

In fact, the stocks of several energy companies plunged 20% or more this week after unveiling weak quarterly results and watering down their outlook. Among the biggest losers, according to data from S&P Market Intelligence, were Plains All American Pipeline (NYSE: PAA), Plains GP Holdings (NYSE: PAGP), Key Energy Services (NYSE: KEG), and Smart Sand (NASDAQ: SND).
