24 factors that power Stoquity's stock scoring model — each analyzed with key metrics, historical performance data, academic research, and practical portfolio insights.

A factor is a measurable attribute of a security that explains differences in returns. Factor investing systematically harvests these return premiums, moving beyond stock-picking intuition toward evidence-based portfolio construction.

Based on the Fama–French five-factor model and extensions

What Is Factor Investing?

Factor investing is an investment strategy that targets specific, quantifiable characteristics — or "factors" — that academic research and empirical evidence have shown to drive stock returns over time. Rather than trying to pick individual winning stocks, factor investors build portfolios that systematically tilt toward securities sharing these proven attributes.

The concept emerged from Nobel Prize-winning research by Eugene Fama and Kenneth French, who demonstrated that market returns alone couldn't explain all stock performance. Their work identified additional dimensions — value, size, profitability, and investment patterns — that persistently explained return differences across stocks and time periods.

◆ Why Factors Matter for Every Investor

Whether you're a passive index investor or an active stock picker, factors shape your portfolio's behavior. Understanding which factors you're exposed to — intentionally or not — is the first step toward smarter investing. A portfolio heavy in tech growth stocks, for example, has very different factor exposures than one concentrated in utility dividend payers.

How Stoquity Uses Factors

Stoquity's scoring engine evaluates every stock across all 24 factors below. Each stock receives a composite score from 0 to 100 based on its factor profile, adjusted for sector context and market regime. This transparent, rules-based approach removes emotional bias and provides a consistent framework for comparing investment opportunities.

Valuation 4 factors

Valuation factors identify stocks trading below their intrinsic worth. These metrics compare market price to fundamental measures like earnings, book value, and cash flow — the cornerstone of value investing pioneered by Benjamin Graham and refined by decades of academic research.

Quality 6 factors

Quality factors measure the financial health and operational excellence of a business. Companies with high profitability, stable earnings, strong returns on capital, and healthy margins tend to deliver superior risk-adjusted returns over full market cycles.

Growth 3 factors

Growth factors capture companies expanding their revenue, earnings, and dividends at above-market rates. Growth investing targets businesses with compounding potential — but the key is distinguishing sustainable growth from temporary surges.

Income 2 factors

Income factors evaluate a company's ability to generate and distribute cash to shareholders. Dividend yield and cash flow metrics help identify reliable income-generating investments, particularly valuable in low-rate environments.

Momentum 4 factors

Momentum factors exploit the empirical tendency of recent winners to continue outperforming and recent losers to continue underperforming. Sentiment signals from analysts, earnings surprises, and insider behavior add conviction layers to price-based signals.

Risk 5 factors

Risk factors assess the downside potential and structural vulnerabilities of an investment. Volatility, leverage, and liquidity metrics help investors avoid hidden dangers and construct more resilient portfolios.
