For investors looking for a disciplined, long-term method to build wealth, few strategies have the substance of Peter Lynch's approach. As the famous manager of Fidelity's Magellan Fund, Lynch supported a philosophy of investing in what you understand and concentrating on companies with solid fundamentals, lasting growth, and fair valuations. His method, often called Growth at a Reasonable Price (GARP), steers clear of speculative stocks for profitable, financially stable businesses that can be owned for years. A stock screener built on his main criteria, including earnings growth, valuation, profitability, and financial condition, can help find possible choices that match this proven strategy.

One company that recently appeared from such a screen is PTC Inc. (NASDAQ:PTC), a global software company focused on computer-aided design (CAD), product lifecycle management (PLM), and industrial Internet of Things (IoT) solutions. Based in Boston, PTC supplies the digital foundation for companies to design, manage, and service complicated physical products, a market with lasting, long-term demand.
Match with Lynch's Main Criteria
Peter Lynch stressed a balanced group of quantitative filters to find companies increasing at a lasting speed without paying too much for that increase. PTC's present financial picture shows a solid match with these ideas.
- Lasting Earnings Growth: Lynch preferred companies with a steady earnings growth history between 15% and 30%, seeing growth outside this range as possibly not lasting. PTC's five-year average EPS growth rate of 25.6% fits well within this target area, showing a record of strong, yet not excessive, increase.
- Fair Valuation (The PEG Ratio): Maybe the central part of Lynch's valuation test is the Price/Earnings to Growth (PEG) ratio. A PEG of 1.0 or less implies the market may not be completely valuing the company's growth path. PTC's PEG ratio, based on its past five-year growth, is about 0.69. This signals the stock may be priced attractively compared to its historical earnings growth, a main point for GARP investors.
- Solid Profitability (Return on Equity): Lynch searched for companies that effectively produce profits from shareholder equity. A high Return on Equity (ROE) is a sign of a good business. PTC's ROE of 19.2% not only exceeds Lynch's usual 15% limit but also places well within the competitive software field, showing capable management and a profitable way of operating.
- Careful Financial Condition: To stay away from high risk, Lynch focused on companies with sturdy balance sheets. His rules involved a Debt-to-Equity ratio below 0.6 (with a personal liking for under 0.25) and a Current Ratio above 1.0 to make sure short-term liquidity. PTC satisfies both conditions, with a Debt-to-Equity ratio of 0.31 and a Current Ratio of 1.12, indicating a cautious method to financing and a capacity to meet its near-term responsibilities.
Fundamental Condition Review
A wider look at PTC's fundamental analysis report on Chartmill supports the image shown by the Lynch screen. The company gets a good total fundamental rating of 7 out of 10, with specific strong points in two important areas Lynch would value.
- Profitability is a Strength: PTC's profitability score is a high 9 out of 10. The company has notable margins, with a Gross Margin over 83% and an Operating Margin near 37%, which place it with the best in its field. Its Return on Invested Capital (ROIC) of nearly 15% further supports its effectiveness.
- Financial Condition is Good: The company's health score is a solid 7 out of 10. While its liquidity ratios (Current and Quick Ratio) are seen as average compared to similar companies, its solvency is strong. With an Altman-Z score signaling low bankruptcy risk and a controllable debt level, the overall financial base seems stable, a requirement for a long-term investment.
The valuation score of 5 out of 10 shows a varied but fair view. While its standard P/E ratio is below both the field and S&P 500 averages, its Price-to-Free-Cash-Flow and Enterprise Value/EBITDA ratios also suggest a valuation that is fair compared to similar companies. This matches the GARP goal of avoiding both deep-value problems and very high-priced growth stocks. You can see the complete, itemized fundamental breakdown for PTC here.
Growth Path and Points to Think About
For a Lynch-type investor, past performance is only useful if future possibility remains. PTC's growth story is connected to the digital change of manufacturing and engineering. Its set of CAD, PLM, and IoT tools is key to movements like digital twins and smart, connected products. While the fundamental report states that the high growth rates of recent years are anticipated to slow, a normal event as companies get older, analyst forecasts still predict a good revenue growth rate moving ahead.
This possible reduction in growth rate is a significant point for investors to study more, following Lynch's suggestion to "do your homework." It shows why the Lynch screen begins the process but does not finish it; knowing the business reasons behind the figures is necessary.
A Choice for More Study
PTC Inc. offers a strong example of a company that meets a strict, rules-based screen drawn from Peter Lynch's strategy. It shows a history of solid, lasting earnings growth, is priced at a fair valuation as seen by the PEG ratio, shows high profitability, and keeps a careful balance sheet. These are exactly the basic qualities Lynch wanted for a long-term portfolio.
