What Happened?
A number of stocks jumped in the afternoon session after oil and gas prices surged amid reports the U.S. was planning an extended blockade of Iranian ports.
Brent crude, a key international oil benchmark, rose 5% to nearly $117 a barrel, its highest level since the conflict with Iran began. The price increase raised concerns that the situation, could persist for much longer, creating broad uncertainty in the energy markets. For oil and gas producers, higher commodity prices generally translate to increased revenues and profitability, which often makes their stock more attractive to investors. Adding to the volatility, the United Arab Emirates announced its departure from the OPEC oil cartel, introducing a new layer of uncertainty for global supply. This combination of geopolitical risk and rising commodity prices contributed to the broad market decline as investors grew more cautious.
The stock market overreacts to news, and big price drops can present good opportunities to buy high-quality stocks.

Zooming In On Kosmos Energy (KOS)
Kosmos Energy’s shares are extremely volatile and have had 81 moves greater than 5% over the last year. In that context, today’s move indicates the market considers this news meaningful but not something that would fundamentally change its perception of the business.
The previous big move we wrote about was 16 days ago when the stock gained 3.2% on the news that news of a planned U.S. blockade of the Strait of Hormuz sparked concerns over significant oil supply disruptions.
The potential military action in the critical shipping lane for oil exports sent crude prices soaring. Both Brent crude, the international benchmark, and U.S. West Texas Intermediate crude jumped over 7%, climbing above $102 a barrel. This surge was in direct response to the U.S. plans to block ships to and from Iran via the Strait, a move that could severely restrict oil exports and tighten global supplies. Consequently, investors flocked to energy stocks, anticipating that sustained higher oil prices would translate into increased revenues and profitability for producers.
Kosmos Energy is up 244% since the beginning of the year, and at $3.08 per share, it is trading close to its 52-week high of $3.10 from April 2026. Investors who bought $1,000 worth of Kosmos Energy’s shares 5 years ago would now be looking at an investment worth $1,053.
