Investors looking for a disciplined, long-term method for choosing stocks frequently consider the principles of legendary fund manager Peter Lynch. His strategy, detailed in his book One Up on Wall Street, focuses on finding companies with strong, lasting growth that are available at sensible prices, a philosophy often called Growth at a Reasonable Price (GARP). Lynch supported investing in understandable businesses with sound financial condition, good profitability, and valuations that do not overpay for future expectations. A key instrument for using this method is a stock screener that filters for specific measures, such as steady earnings growth, a low price-to-earnings to growth (PEG) ratio, acceptable debt, and high returns on equity.

One company that recently appeared from such a Peter Lynch-inspired screen is CARGURUS INC (NASDAQ:CARG), the operator of a well-known online automotive marketplace. The platform connects car buyers and sellers, providing digital retail and wholesale solutions. For investors following Lynch's philosophy, CarGurus presents an interesting case study in how a modern, technology-enabled service in a recognizable sector can fit with established investment rules.
The center of Lynch's strategy is to find companies expanding at a maintainable rate, funded carefully, and valued appealingly relative to that expansion. CarGurus seems to meet several of these numerical checkpoints based on the provided screening data.
A closer examination of the company's wider fundamental profile supports the initial screening results. According to a detailed fundamental analysis, CarGurus receives an overall rating of 7 out of 10, with specific strong points in profitability and financial condition.
The analysis notes that CarGurus functions with sector-leading margins and returns, including a Gross Margin of 88.2% and a Return on Invested Capital (ROIC) of 23.5%. Its clean balance sheet, noted by no debt and a high Altman-Z score, indicates very low bankruptcy risk. While revenue growth is presently moderate, the company's earnings growth remains solid, and its valuation measures like the Price/Forward Earnings ratio are viewed as sensible compared to both its industry group and the wider S&P 500.
For the GARP investor using a Lynch-like method, CarGurus represents a noteworthy possibility. It functions in a large, understandable market, automotive sales, using technology to make transactions easier. The numerical screening measures point out its mix of past growth, high profitability, and a careful capital structure. Most significantly, its low PEG ratio implies the market may not be completely valuing this mix, providing a potential "sensible price" entry point.
Peter Lynch supported the idea of detailed research after a screen finds a candidate. The measures shown here give a solid foundational thesis, suggesting CarGurus justifies more examination for a place in a diversified, long-term portfolio.
