Why These Energy Stocks Are Losing This Week

In this article, we are going to discuss the energy stocks that are losing this week.

The American shale sector suffered a setback last weekend after the world’s largest group of oil producers, OPEC+, announced yet another big increase of 411,000 barrels per day in oil production for the month of July. The move marks the latest push by the coalition to punish its rogue members and recoup lost market share.

Harry Tchilinguirian, analyst at Onyx Capital Group, stated:

“Today’s decision only goes to show that market share is on top of the agenda. If price will not get you the revenues you want, they are hoping that volume will.”

The WTI crude oil price has plunged by around 25% since last summer and is currently hovering just over the $63 mark. This creates a lot of uncertainty for the US shale producers to drill new wells profitably, as they require WTI prices starting at $61 per barrel and reaching $70 for the Permian Basin, outside the Delaware Basin part of it. The shale drilling sector is already faced with rising material costs and natural depletion, so the latest decision by OPEC+ only adds to their troubles.

9. Hallador Energy Company (NASDAQ:HNRG) 

Share Price Decline Between May 27 – June 3: 5.47%

With its roots in oil and gas exploration, Hallador Energy Company (NASDAQ:HNRG) has evolved to concentrate on coal development and transportation delivery. The company is also pivoting towards power generation over coal production amid a tough outlook for fossil fuels in the US.

After closing at an all-time high of $19.4 last month, Hallador Energy Company (NASDAQ:HNRG) has been under pressure after the company disclosed that its agreement with a datacenter developer, which granted exclusivity in a potential power supply deal, has been terminated by the counterparty. Moreover, the company’s shareholders approved the Second Amended and Restated 2008 Restricted Stock Unit Plan last week, increasing the number of shares available for issuance by 2,000,000 and extending the plan’s term until May 29, 2035.

However, despite the recent setback, Hallador Energy Company (NASDAQ:HNRG) has delivered an impressive return of more than 87% over the last year.
