The investment philosophy created by Peter Lynch focuses on finding companies with good growth potential that are available at fair prices, a method often called Growth at a Reasonable Price (GARP). Lynch's system, explained in his book One Up on Wall Street, centers on lasting earnings growth, sound financial condition, and good valuation measures, particularly using the PEG ratio to locate companies that are not priced too high compared to their growth. This method steers clear of the most extreme growth stocks and deep value investments, looking instead for businesses that can provide steady, long-term results.
Qualys Inc. (NASDAQ:QLYS), a company that offers cloud security and compliance solutions, was recently identified by a stock screen using Lynch’s standards. The company’s nature as a cloud-based security platform fits with Lynch’s idea of investing in easy-to-understand businesses that offer necessary services, here, assisting organizations with their IT security and compliance requirements via a software-as-a-service model.
Meeting the Lynch Criteria
The screen uses a number of specific filters to find appropriate companies, and Qualys satisfies these important measures:
Fundamental Analysis Overview
A wider fundamental review of Qualys supports the results from the Lynch-based screen. The company gets a solid total rating of 7 out of 10, with very good grades in profitability (9/10) and financial health (9/10). Its profit margins are excellent for the software industry, and its total absence of debt gives it a very strong financial standing. While its valuation is viewed as acceptable instead of very low, its high profitability is considered to support the current price levels. The primary point to watch is an expected reduction in future growth relative to its past performance, a detail long-term investors should observe. A complete analysis is provided in the full fundamental report.
Alignment with Long-Term GARP Investing
For investors looking for growth at a fair price, Qualys offers a strong argument. It represents the Lynch idea of a clear business in a necessary field, cybersecurity, that is expanding at a maintainable rate. Its high profitability, excellent balance sheet, and fair valuation when considered with growth (PEG < 1) offer a degree of safety. These traits are exactly what GARP investors seek: a good company where you are not paying too much for its future earnings, thus setting it up for possible long-term gains.
The Peter Lynch screen is a useful initial step for finding companies that match a structured GARP plan. For investors wanting to research other companies that meet these standards, the screen is ready to use, giving a changing list of possible investment options.
