Peter Lynch’s investment strategy, described in One Up on Wall Street, centers on finding companies with steady growth at fair prices, commonly known as the Growth at a Reasonable Price (GARP) method. The approach highlights financial stability, earnings strength, and controlled growth, steering clear of overly hyped or debt-heavy firms. By looking for consistent earnings growth, favorable PEG ratios, solid balance sheets, and strong returns on equity, Lynch’s strategy aims for businesses that can grow steadily over time without depending on speculative trends.
QUALYS INC (NASDAQ:QLYS) appears to match this model. The cloud security and compliance company shows reliable profitability, measured growth, and a solid financial foundation, traits Lynch valued. Next, we review how QLYS meets the strategy’s key requirements.
Steady Earnings Growth
Lynch preferred firms with earnings per share (EPS) growth in the 15% to 30% range, balancing growth and stability. QUALYS’s 5-year EPS growth of 21.2% fits this range, showing consistent progress without excessive risk. The company’s subscription-based cloud model also ensures reliable revenue, a quality Lynch favored.
Fair Valuation Using PEG Ratio
The PEG ratio (Price/Earnings adjusted for growth) helps spot reasonably priced growth stocks. Lynch viewed PEG ≤ 1 as ideal. QUALYS’s PEG of 0.99 indicates its growth potential is fairly priced, aligning with the strategy’s focus on value.
No Debt and Financial Strength
Lynch avoided companies with high debt, favoring debt-to-equity ratios below 0.6 (preferably under 0.25). QUALYS’s 0.0 D/E ratio, along with a current ratio of 1.39, shows strong liquidity and no dependence on borrowing, reducing risk in tough economic times.
Strong Return on Equity (ROE)
ROE measures how well a company uses shareholder equity to generate profits. Lynch looked for ROE above 15%; QUALYS’s 36.4% ROE beats 92.5% of software industry peers, reflecting efficient use of capital, a trait Lynch associated with strong performers.
