A systematic method for growth investing can help investors find companies with solid fundamental momentum. One such system comes from Louis Navellier's "The Little Book That Makes You Rich," which lists eight specific rules for picking leading growth stocks. These rules focus on earnings revisions, surprises, sales growth, margin expansion, cash flow strength, earnings growth, earnings momentum, and return on equity. When used with a stock screener, this method can identify companies showing outstanding financial performance, such as Halozyme Therapeutics Inc (NASDAQ:HALO).
The method highlights positive earnings revisions and surprises as early signs of possible outperformance. When analysts increase their estimates, it often shows confidence in the company's near-term future. In the same way, consistent earnings beats can push future estimate revisions higher.
These numbers show that Halozyme is regularly surpassing market expectations, forcing analysts to adjust their views, a situation that often comes before positive price momentum.
Increasing sales and earnings growth are central to Navellier's growth investing approach. Companies showing solid expansion in both top-line revenue and bottom-line profits usually gain market notice.
This acceleration across several growth areas suggests Halozyme is gaining market share and improving its operational efficiency at the same time.
The method gives significant weight to expanding operating margins and solid cash flow generation. Margin expansion shows pricing power and operational efficiency, while strong cash flow offers financial flexibility for future growth projects.
These results reveal a company that not only grows quickly but does so profitably, with high returns on shareholder capital and improving cash generation.
Halozyme's complete fundamental rating of 8/10 reflects solid underlying business quality. The company rates especially well on profitability and financial health measures, placing it as a candidate for both growth and quality investing approaches. Despite its solid growth path, the stock seems fairly valued with a P/E ratio of 12.59, which compares well to both industry peers and the wider market. The company's ENHANZE drug delivery technology platform provides a lasting competitive edge, fueling its outstanding financial performance. For a detailed breakdown of these measures, readers can examine the full fundamental analysis report.
Halozyme presents a strong case for investors using the Little Book method, meeting several rules with high scores. The company's technology platform business model creates repeating revenue streams while keeping high margins. Its partnerships with major pharmaceutical companies provide validation and lower development risk. The mix of solid growth, increasing profitability, and fair valuation creates an appealing risk-reward profile for growth-focused investors.
For investors interested in finding other companies that meet these strict growth rules, the Little Book strategy screen provides regularly updated results based on Navellier's eight rules.
