End the Year Strong With These 3 Comeback Champions

With cracks appearing in the S&P 500 after a strong rally, investors may rotate into idiosyncratic names poised for year‑end momentum: Delta Air Lines, Diamondback Energy and HEICO. Delta, with an 11.2% operating margin, a Q3 EPS beat but modest 4% YoY revenue growth, a strengthening loyalty program and rising business travel, is targeting sustained double‑digit margins and up to $4 billion in free cash flow; it carries a unanimous Buy from 21 analysts, a P/E of 7.9 and >28% upside potential. Diamondback has started to rebound after a sluggish 2025, delivering Q3 EPS and revenue beats, a 36% reinvestment rate, and potential tailwinds from a ~21% jump in gas prices plus project exposure that underpin analyst optimism and >28% upside. HEICO has outperformed YTD (+31%) but has been flat since June; its acquisition-driven growth (most recently Axillon’s fuel containment unit) and a June dividend hike boost scope but pressure cash and add debt risk ahead of mid‑December results, leaving 10 of 17 analysts with Buy ratings and roughly 11%+ upside.

Analysis

As the S&P 500 shows early signs of strain after a strong rally, investors are spotlighting idiosyncratic names that could outperform into year-end. Delta Air Lines experienced a stall in its recovery after a government shutdown disrupted travel, with shares having dipped below $36 in April and largely flat since August; the carrier beat Q3 EPS but revenue rose only 4% year‑over‑year, while operating margin remains strong at 11.2% and management forecasts sustained double‑digit margins and up to $4.0 billion in free cash flow. Delta carries a unanimous Buy from 21 analysts, trades at a P/E of 7.9 and is projected to have >28% upside, driven by premium product growth, loyalty program strength and a rebound in business travel. Diamondback Energy reported Q3 EPS and revenue beats, a 36% reinvestment rate year‑to‑date and has seen natural gas prices rise roughly 21% in the last quarter, supporting potential upside alongside project exposure to Competitive Power Ventures and data‑center contracts; analysts similarly price >28% upside. HEICO has outperformed YTD (+31%) but has been flat since June; acquisition activity including Axillon’s fuel containment business and a June dividend increase have pressured cash and elevated leverage concerns ahead of mid‑December earnings, where 10 of 17 analysts remain Buyers and Street sees ~11% upside.

Key Decisions for Investors

• Consider initiating or adding to Delta positions on valuation (P/E 7.9) and consensus upside (>28%), but size exposure to reflect dependence on near‑term travel normalization and verification of management’s free‑cash‑flow realization, monitor Q4 margins and holiday/business travel trends
• Tactically overweight Diamondback to capture upside from the recent Q3 beat and ~21% rise in gas prices, but limit conviction until commodity strength and materialization of data‑center/Competitive Power Ventures revenues are confirmed
• Avoid adding to HEICO ahead of mid‑December earnings; maintain or trim positions and consider hedging exposure given acquisition‑driven cash pressure and rising debt risk, increase exposure only if free cash flow and leverage metrics improve
• Track macro triggers — resolution of travel‑disrupting government actions, natural gas price trajectories, and each company’s upcoming quarterly reports — as primary catalysts to re‑rate positions
