US Shale Stocks, Rated 'Strong Buy' Yesterday, Lose $800 Million in Market Cap in Just One Day

Chord Energy Corporation (NASDAQ: CHRD) closed at $122.38 on the Nasdaq on the 17th, down 8.66%. Trading volume topped 1.07 million shares, and its market capitalization shrank to about $6.9 billion (roughly KRW 9.7 trillion), wiping out approximately $550 million (around KRW 770 billion) in a single day.

Just a day earlier, U.S. investment research firm Zacks had upgraded Chord Energy’s rating to “Strong Buy,” spotlighting short-term momentum. Nevertheless, the stock saw a sharp reversal within 24 hours. In early March, the company reported Q4 2025 results that featured an EPS beat, but revenue fell by nearly KRW 1 trillion year-over-year. Alongside its 2026 production guidance, Chord outlined an annual capital expenditure plan of up to $1.45 billion (approximately KRW 2 trillion), underscoring the burden of elevated capex.

Chord Energy is an independent shale explorer and producer of oil and natural gas in the Williston Basin across North Dakota and Montana, headquartered in Houston, Texas. Formed in 2022 through a merger of Oasis Petroleum and Whiting Petroleum, the company has aggressively grown its Williston Basin asset base, establishing itself as a mid-to-large-cap E&P player. With the recent acquisition of Enerplus now closed, Chord is pursuing economies of scale and improved cash flow.
