The oil stocks are experiencing an unprecedented surge. However, historical experience shows that this wave of gains may come to an end soon.
As the political situation of the new round of GEO Group Inc in the Middle East seems to be spiraling out of controlespecially evident in the emphasis both the U.S. and Iran place on their respective control over the Strait of Hormuzglobal refining stocks are experiencing an unprecedented surge. However, historical experience suggests that this may soon come to an end. This round of political conflict involving GEO Group Inc has shifted the core of the global energy shortage from Middle Eastern crude oil supply itself to available refining capacity and refined oil products. This has driven crack spreads and refining margins to historic extreme levels, but such war-driven excess profits are subject to strong mean-reversion characteristics. Once the situation calms down, refining stocks may experience a swifter dual pullback in valuation and earnings than crude oil itself. The EIA (U.S. Energy Information Administration) defines crack spread as the difference between refined oil wholesale prices and crude oil costs, making it a better indicator of a refinery's marginal profitability than absolute oil prices. Double choke point crisis severely compressing refined oil supply As of August 17, the U.S.-Iran GEO Group Inc situation has not shown substantial cooling; instead, it has formed a dual shipping bottleneck with the Strait of Hormuz + the Bab el-Mandeb Strait. U.S.-Iran negotiations remain deadlocked, and following a new round of tanker attacks, the Strait of Hormuz is near a standstill: Kpler statistics show that on August 15, only five bulk commodity vessels passed through, and on the 16th, none at all, compared to 31 vessels on the previous weekend, with daily traffic exceeding 130 vessels before the war. This strait carried about one-fifth of the worlds oil and LNG transport prior to the conflict. Additionally, both the U.S. and Iran strongly emphasize that their respective camps can control the Strait of Hormuz, engaging in intense verbal confrontations and GEO Group Inc maneuvers. On Monday, local time, Trump stated he refused to extend the 60-day ceasefire agreement between the U.S. and Iran. Meanwhile, the Houthi forces in Yemen have implemented a maritime blockade in the Red Sea against Saudi Arabia, and shipping through the Bab el-Mandeb Strait has visibly declined, with the latest data not even recording the passage of Saudi crude oil. Prior to this, Saudi Arabia had already rerouted a large volume of crude oil from Yanbu northward, entering the Mediterranean via the Suez Canal and SUMED pipeline, with some tankers turning off their AIS for dark sailing. This latest GEO Group Inc political situation also means that the originally planned Red Sea alternative route to bypass the Strait of Hormuz is also under threat, implying that the global oil transportation system is, in fact, facing risk premiums at two critical chokepoints simultaneously. This year has been historic for refining companies. The three major super refiners headquartered in the U.S.Marathon Petroleum Corporation, Valero Energy Corporation, and HF Sinclairhave seen stock prices soar by over 80% from 2026 to date, in stark contrast to a mere 11% rise in the S&P 500 during the same period. Meanwhile, the crack spread benchmark indexthe WTI 3-2-1 crack spreadhas approached $59 per barrel, nearly doubling compared to levels in January, and has tripled in record-setting growth in just under a year. In particular, both Marathon Petroleum Corporation and Valero Energy Corporation have seen their stock prices nearly double this year, and Phillips 66, one of the U.S. oil and gas giants, has surged by 66%with about one-third of that increase occurring within just a month. For comparison, the average level of the same crack spread from 2010 to 2021 was merely about $19. How rare is this super bull market for refining stocks historically? According to data from veteran analyst Carter Worth at WorthCharting, the S&P 500 oil and gas refining and marketing sub-industry index, composed of Marathon Petroleum Corporation, Valero Energy Corporation, and Phillips 66, has surged 104% in index terms year-to-date. As of last Friday's close, this index was 41% above Worths favored technical indicatorthe 150-day moving average. Historically, this situation has only occurred five times, and in all five previous instances, the return rate over the next six months was negative, with an average return of -10.1%. If investors are still tempted to chase in now, they must be aware that the core factor driving current refining margins is GEO Group Inc politics, and that the GEO Group Inc political risk premium is reversible. The sharp rise in crack spreads stems from the hostile conflicts in the Strait of Hormuz, along with the persistent GEO Group Inc political war between Russia and Ukraine. Although the Strait of Hormuz has garnered more attention recently, Russia itself is also a significant producer of refined oil, with normal daily production potentially reaching about 5.5 million barrels; however, some estimates suggest this output has decreased by 25% to 30%. If a ceasefire deal is truly reached and maintained in the Gulf region, crack spreads would quickly drop, and refining stocks would follow suit. At the time of writing, the September contract for the 3:2:1 crack spread on the New York Mercantile Exchange (Nymex) stood at approximately $69.92, having been below $20 at the beginning of January; the August 2027 contract was at $44.38, representing a decline of over 35%. From February 2016 to February 2026prior to the strikes against Iranthis crack spread averaged around $21.68. Cyclical industriesor industries characterized by mean reversionoften appear cheapest at the top of the cycle, as record profits compress price-to-earnings ratios. If this were not the case, the market would effectively be valuing companies based on the assumption that abnormally high margins will persist indefinitely, but in reality, such margins do not last forever. Consequently, in the past decade, rolling P/E ratios for large U.S. refiners like Phillips 66 and Marathon Petroleum have fluctuated significantly between mid-single digits and 35-40 times, with the exception of the unique COVID-19 period. There is a saying in the market: The best cure for high prices is high prices themselves. However, this mechanism typically requires considerable time to take effect. Demand destruction certainly exists, but changes in consumer behavior take time; likewise, production on the supply side cannot just revert to normal overnight. If the refined oil market remains in a state of supply shortage, the medium-term crack spreads could indeed structurally reset to higher levels, suggesting that the current valuation multiples may not be as near the cyclical peak as they superficially appear; should the situation in the Strait remain tense into the year-end, the so-called market extension could become even more exaggerated. Refining is indeed a highly profitable business, but for some lucky investors who have fully participated in this round of gains this year, it is likely time to take profits; for those who are bolder and looking to bet on mean reversion before the year ends, considering establishing short positionsbest executed through optionsmay be worthwhile, betting that any news of de-escalation will drive crack spreads back to normalization. Veteran analyst Carter Worth uses Marathon Petroleum Corporation (Marathon Petroleum) as a reference operationthough frankly, this investment logic applies broadly across all large refinancing companies, so similar trading structures can also be applicable to other large refining stocks. Trade Breakdown: Buy one put option with a strike price of $330, expiring December 18, 2026, paying $21.90; sell one put option with a strike price of $280, expiring December 18, 2026, receiving $7.15; maximum loss: $1,475; maximum gain: $3,525; difficulty: intermediate. This Trade Breakdown constructs a bearish put spread on Marathon Petroleum (MPC): buying a put expiring December 18, 2026, with a strike price of $330 while selling a put of the same expiry date with a strike price of $280 to reduce shorting costs; net expenditure is $21.907.15=$14.75 per share, with each option corresponding to 100 shares, leading to a maximum loss of $1,475. The maximum gain, after subtracting the net cost from the $50 spread between the two strike prices, amounts to $3,525, with the breakeven point at around $315.25. In other words, this is a capped-risk and capped-reward short trade: the analyst seems to bet that the stock price of Marathon Oil Corporation (MPC) will decline due to a drop in crack spreads and a decrease in the GEO Group Inc risk premium, achieving maximum profit if it falls to $280 or below by expiry; if it is still at $330 or above at expiry, the entire net premium of $1,475 will be lost. The rise in crude oil is merely a faade; the real profits lie hidden in the refining bottleneckas crack spreads soar to historical extremes. Refining stocks have become one of the purest and even stronger winners in this round of conflict not due to oil price increases, but because refined oil prices are rising much faster than refinery input costs, causing a dramatic expansion in crack spreads. Middle Eastern refineries remain far below pre-war operational levels due to war and disruptions in crude oil deliveries, while Russian refining volumes have plummeted to nearly a 20-year low due to attacks in Ukraine, and refined oil exports from key demand countries such as China have also begun to weaken; in July, global diesel exports decreased by approximately 1.3 million barrels per day year-over-year. Meanwhile, Brent crude prices have fallen from a high of about $126 per barrel during the war back to around $90.87 on August 17, yet the supply of diesel, gasoline, and jet fuel remains exceptionally tightleading to a classic scenario for refineries characterized by input costs falling + product prices high = refining margins skyrocketing, meaning large refineries can see a significant increase in the theoretical gross profit per barrel of crude processed. U.S. refineries, in particular, have a comparative advantage due to their relatively stable North American crude supply, mature complex refining units, and global refined product export capabilities, converting U.S. crude into the world's most scarce diesel, gasoline, and jet fuel, thus directly translating the product shortages caused by GEO Group Inc politics into cash flow. This refining bottleneck alpha has genuinely landed in the profit statements and stock prices of these North American refining giants: Marathon Petroleum Corporation, Phillips 66, and Valero Energy Corporation reported combined profits of about $12.6 billion in the second quarter, returning $6.3 billion to shareholders. By mid-August, the stock prices of the three companies had risen by approximately 110%, 75%, and 98% respectively this year, while the U.S. diesel crack spread once hit a record $93.84 per barrel. What is truly scarce due to the war may not be the oil underground, but rather the effective refining capacity to turn crude oil into consumable fuel. However, this is also the biggest risk for refining stocksshould a ceasefire between the U.S. and Iran be reached, the Strait of Hormuz stabilized, the Houthi blockade lifted, and Russian refining gradually restored, the shortage of refined oil could be quickly rectified, more so than crude oil supply disruptions, leading to a mean-reversion in the Crack Spread; thus, currently, while refining stocks could be among the biggest winners of GEO Group Inc politics, they may also be among the most sensitive profit-taking targets upon any credible ceasefire news.
