Gulfport Energy Corporation is a U.S.-based independent exploration and production company with a focus on large-scale natural gas and liquids development in resource-rich shale plays.
Gemmstock Limited, a London-based investment manager, recently bought more than $18 million worth of Gulfport Energy stock, bringing its holdings to over $34 million as of September 30, 2025. Here's what average investors need to know.
For starters, Gulfport is relatively small energy production company, which is highly-leveraged to natural gas production in the U.S. Therefore, Gemmstock's acquisition is a bullish bet on US energy production. Moreover, as energy producers are highly affected by the price of the commodities they bring to the surface, Gemmstock is also taking a stance on natural gas prices as we head into the winter in the northern hemisphere.
As for performance, Gulfport has solidly outperformed key benchmarks over the last three years. Since 2022, the stock has generated a total return of 151%, equating to a compound annual growth rate (CAGR) of 36%. That beats the S&P 500, which has generated a total return of 71% over the same period, with a CAGR of 19.7%.
What's more, Gulfport has also bested the performance of key exchange-traded funds (ETFs) within the energy sector, such as the State Street SPDR S&P Oil & Gas Expl & Prod ETF (XOP) and the Energy Select Sector SPDR Fund (XLE). Those funds have produced total returns of -9% and 7%, with CAGRs of -3.3% and 2.4%, respectively.
In summary, investors who are seeking exposure to the energy sector may want to consider Gulfport, due to this recent large institutional purchase, in addition to the stock's solid performance history versus market and industry benchmarks.
