Valero Energy (VLO) has reached a new 52-week high of $362.79, gaining 120.5% year-to-date and outperforming its sector. The company maintains a strong earnings track record with a Zacks Rank #1 (Strong Buy) rating and an A-rated VGM Score. Despite trading at peer-average valuations on forward P/E, the stock shows a low PEG ratio of 0.41, suggesting potential for continued gains. However, earnings are expected to decline 27.44% in the next fiscal year.

Three midstream energy companies—Enbridge, Enterprise Products Partners, and MPLX—offer attractive dividend yields and strong compounding potential. Operating as 'energy tollbooths' with stable cash flows, these stocks have demonstrated consistent dividend/distribution growth over decades, making them suitable for passive income investors seeking long-term capital appreciation.

Refiner stocks have significantly outperformed the broader energy sector and S&P 500 due to a global shortage of refining capacity, which has driven crack spreads (refiner profit margins) to record highs of $64. Despite geopolitical conflicts and infrastructure damage reducing global refining capacity by 5 million barrels per day, the author recommends investing in refiners as the capacity shortage will persist longer than oil price volatility.

Tech stocks rallied on Monday while industrial stocks lagged, with the Nasdaq up 0.57% and the Dow down 0.30%. Alphabet surged 3% after reports of a new AI chip called 'Frozen v2' that runs Google's Gemini models more efficiently. The semiconductor sector broadly rallied on the news. However, Apple fell 2.4% and Caterpillar dropped 1.2%, offsetting gains. Over 300 companies report earnings this week, with investors seeking clarity on AI spending.

MPLX LP, a midstream pipeline operator, is highlighted as an attractive dividend stock with a 7.3% yield and a track record of consistent payout growth. The company benefits from long-term contracts with Marathon Petroleum, strategic acquisitions in the Permian and Marcellus regions, and exposure to growing natural gas liquids markets. With strong free cash flow generation and a sustainable dividend coverage ratio, MPLX is positioned for long-term dividend growth targeting 12.5% annually through 2027.

Delek US Holdings (DK), a mid-sized oil refiner, has gained 64% year-to-date but remains underappreciated by investors. The company's 'surgical' approach to cost-cutting and operational efficiency has driven a fivefold increase in EBITDA in Q1 2026 without proportional revenue growth. With a 2.1% dividend yield, strong cash position, and Goldman Sachs' $55 price target, the stock merits closer examination despite high debt ratios and volatile refining margins.

Crude oil fell below $96 per barrel while gasoline prices climbed to $4.56 per gallon, creating exceptional profit margins for oil refiners. The 3-2-1 crack spread reached $56.22 per barrel—its highest level since June 2022—as refiners benefit from the widening gap between falling crude costs and stable pump prices. Major refiners reported strong first-quarter earnings that significantly beat consensus estimates.

Marathon Petroleum (MPC) shares surged 3.96% on Wednesday following a quarterly dividend declaration of $1 per share and broad energy sector gains.

Growth is driven by rising fertilizer demand, ultra-low-sulfur diesel (ULSD) refining regulations, and increased rubber/tire manufacturing. Asia-Pacific leads both production and consumption, while emerging applications in lithium-sulfur batteries and construction materials support expansion.
