The S&P 500 has shown cracks recently, leading investors to seek out companies with potential for a year-end surge. Delta Air Lines, Diamondback Energy, and HEICO Corp have had varied trajectories but are expected to perform well by the end of 2025. Delta’s strong margins and loyalty program could drive a resurgence.

Delta Air Lines has faced challenges due to the government shutdown but remains resilient with a strong loyalty program and business travel demand. Despite a revenue miss in the third quarter, Delta’s operating margins are solid at 11.2%. Analysts predict a sustained double-digit operating margin and strong free cash flow, with a projected upside potential of over 28%.

Diamondback Energy has seen a recent rebound after a slow 2025, driven by a strong third-quarter earnings report and rising natural gas prices. The company’s focus on capital discipline and exposure to major projects position it well for growth, with analysts showing unanimous support and an upside potential of over 28%.

Recent acquisitions and a dividend increase have helped diversify the company, but managing debt will be key for future success. Analysts expect HEICO to navigate these challenges successfully, with an upside potential of over 11%.
