Trump says Iran war "close to over" amid hopes for more negotiations
In March 2025, when Delta Air Lines (NYSE:DAL) shares were trading at $43.83 amid a sharp 27% monthly decline, InvestingPro’s Fair Value models identified a compelling opportunity. Thirteen months later, that call has proven remarkably accurate, with the stock climbing to $71.71—a total return of 63.61% that exceeded the initial 48.73% estimated upside.
This success story demonstrates how Fair Value analysis helps investors identify mispriced stocks, find optimal entry and exit points, and make more informed decisions by combining multiple valuation methodologies to determine a stock’s intrinsic worth. For investors seeking current opportunities, the most undervalued stocks list provides regularly updated Fair Value opportunities across global markets.
Delta Air Lines, one of America’s largest carriers with a market capitalization of $46.85 billion, operates a diversified business model spanning passenger travel, cargo services, and loyalty programs. When InvestingPro flagged the stock as undervalued on March 28, 2025, Delta was generating $61.6 billion in annual revenue with $8 billion in EBITDA and earnings per share of $5.39. Despite these solid fundamentals and a strong financial health score of 3.85, the stock had suffered through volatile performance in early 2025.
The Fair Value analysis identified significant upside potential, setting a target of $65.19 against the then-current price of $43.83. Key strengths supporting the bullish thesis included Delta’s dominant hub positions, diversified revenue streams from premium products and loyalty programs, and effective cost management—all factors that would prove crucial as the airline navigated industry headwinds over the following year.
The investment thesis unfolded better than anticipated. From the March 2025 entry point, Delta shares delivered strong returns through various market conditions, ultimately reaching $71.71 by April 2026. This 63.61% gain substantially outperformed the initial Fair Value estimate, validating the model’s identification of the mispricing. The stock’s current price now trades closer to its updated Fair Value of $68.11, suggesting the market has recognized Delta’s intrinsic worth.
Recent developments have supported Delta’s fundamental improvement. Revenue has grown to $65.2 billion while earnings per share increased to $6.89, demonstrating operational progress. The company has committed to significant fleet expansion with orders for 34 Airbus jets and 30 Boeing 787-10 aircraft, positioning for future growth. Delta raised its Q1 revenue outlook, sending shares up 4% in premarket trading, and analysts have maintained positive ratings with price targets ranging from $58 to $83.
