Qualys Inc (NASDAQ:QLYS) Passes Peter Lynch's GARP Investment Screen

Last update: Jan 12, 2026

For investors looking for a systematic method to build wealth over time, the ideas from famous fund manager Peter Lynch present a strong structure. His method, often called Growth at a Reasonable Price (GARP), centers on finding profitable, financially healthy companies with steady growth rates that the market does not yet price too high. The central thought is to locate these "tenbaggers", stocks that can increase ten times in value, by putting money into businesses that are easy to understand and have solid basics, frequently before they gain widespread attention on Wall Street. A filter using Lynch's measures recently pointed to Qualys Inc (NASDAQ:QLYS) as a possible option that deserves more study.

Looking at Qualys Using Lynch's Ideas

Peter Lynch stressed a number of numerical checks to reduce the wide field of stocks to a shorter list of good possibilities. Qualys seems to satisfy these important tests, which are made to find companies with lasting growth, fair prices, and a solid financial position.

  • Lasting Earnings Growth: Lynch liked companies increasing steadily, not extremely fast. He usually wanted a 5-year earnings per share (EPS) growth rate from 15% to 30%. Growth over 30% was seen as possibly not maintainable. Qualys shows a 5-year EPS growth rate of 21.2%, putting it directly inside Lynch's desired zone. This shows a past of strong, but not excessive, profit growth.
  • Fair Price Using the PEG Ratio: To prevent paying too much for growth, Lynch used the Price/Earnings to Growth (PEG) ratio heavily, wanting a value of 1 or lower. This measure changes the standard P/E ratio for the company's growth rate, aiding in finding stocks that might be priced low compared to their growth possibility. Qualys has a PEG ratio of 0.92, implying the market may not completely account for its past growth path when seen through this particular view.
  • Solid Financial Condition: A careful balance sheet was essential for Lynch. He chose companies financed more by ownership than by borrowing, often looking for a Debt-to-Equity ratio under 0.6 (and preferably under 0.25). Qualys does very well here with a Debt-to-Equity ratio of 0.0, meaning it functions with no debt that charges interest. This gives notable financial room and lowers risk in poor economic times.
  • Sufficient Cash and High Earnings: Lynch's filter also needed a Current Ratio of at least 1 to make sure short-term bills can be paid. Qualys's ratio of 1.38 shows enough available cash. Also, his method requires high returns on owner investment, with a minimum Return on Equity (ROE) of 15%. Qualys's ROE of 35.7% is very high, showing effective use of investor money to create earnings.

Basic Financial Soundness and Price Setting

Outside the specific filter measures, a wider view of Qualys's basic financial picture supports its position as a high-quality company. The company's overall financial soundness is graded excellent, with no debt payment worries and outstanding profit margins that place near the best in its software industry group. Its Return on Invested Capital (ROIC) of almost 30% is notable, showing very good effectiveness in using money to produce returns.

Regarding price, the situation is varied but depends on the setting. While its standard P/E ratio of 19.55 may seem high alone, it is actually lower than about 75% of its industry competitors. More significantly, its better profitability and clear balance sheet can support a higher price. The PEG ratio under 1, as noted before, is a key Lynch sign that the price may be fair when growth is considered. A complete list of these positives is available in the full basic financial review for QLYS.

Points for the Extended-Term Investor

While the numerical filter shows a positive image, Peter Lynch always highlighted the need for non-numerical understanding. For Qualys, this means acknowledging its part as a supplier of cloud-based security and compliance tools, a field with lasting, extended-term demand trends. The company's software-as-a-service (SaaS) model creates repeating income, which fits with Lynch's liking for reliable business models.

Still, investors should be aware the company's forecasted growth rate is thought to slow from its past speed, a typical issue as companies get older. The extended-term idea would rely on Qualys's skill to perform within its growing market and keep its high levels of profitability and capital effectiveness.

Finding More Possibilities

Qualys stands as one instance of a company that meets a strict group of filters drawn from a tested investment theory. For investors wanting to find other possible options that satisfy these measures for lasting growth at a fair price, the Peter Lynch strategy filter gives a changing beginning point for more study.
