Five Factors (五事) — Complete Guide
What Is the Five Factors Method?
The Five Factors method is Stock Prism's flagship scoring framework. Rooted in Sun Tzu's Art of War, it translates five ancient strategic principles — 道 (Purpose), 天 (Climate), 地 (Terrain), 將 (Leadership), and 法 (Discipline) — into a rigorous, data-driven evaluation of publicly traded companies. Rather than relying on a single metric, the framework assigns a weighted score across all five dimensions and combines them into a composite score from 0 to 100. This holistic approach catches strengths and vulnerabilities that traditional single-ratio analysis often misses.
Historical Origins
In Chapter 1 of The Art of War, Sun Tzu writes: "The art of war is of vital importance to the State. It is a matter of life and death… and must be studied thoroughly." He then introduces five fundamental factors that determine the outcome of any conflict. Stock Prism adapts this framework for the modern investment battlefield: the stock market. Just as a general evaluates terrain before deploying troops, an investor should evaluate a company's competitive landscape before deploying capital. The framework does not predict short-term price swings — it assesses the structural quality and long-term investability of a business.
道 Purpose (15% Weight) — Business Mission & Ethics
Purpose evaluates whether a company has a clear, coherent mission that creates sustainable long-term value. Key data points include: revenue consistency and growth trends over 3-5 years, customer concentration risk (top-customer revenue share), ESG risk scores from third-party providers, and alignment of stated mission with actual business practices. A company scoring high on Purpose generates predictable revenue from a diversified customer base while maintaining ethical operations. A low Purpose score often signals inconsistent revenue, heavy dependence on a single customer, or significant ESG controversies that could erode trust and long-term value.
天 Climate (15% Weight) — Market Environment & Timing
Climate measures the external forces acting on a company — factors largely outside management's control. The analysis examines sector momentum (relative performance of the company's industry), interest-rate sensitivity (how changes in the federal funds rate affect the company's cost of capital and demand), regulatory environment (pending legislation or enforcement actions), and macroeconomic tailwinds or headwinds. A high Climate score indicates favorable conditions — rising sector, supportive policy, healthy consumer demand. A low score warns that even a well-managed company may struggle against structural headwinds such as rising rates, tightening regulation, or shrinking industry demand.
地 Terrain (30% Weight) — Competitive Moat & Financial Bedrock
Terrain is the most heavily weighted factor because a durable competitive advantage is the single best predictor of long-term shareholder returns. Metrics analyzed include: gross margin stability and level (comparison to industry median), operating margin trends, return on invested capital (ROIC) relative to the weighted average cost of capital (WACC), free cash flow conversion, and qualitative moat assessment (brand, network effects, switching costs, patents, cost advantages). Companies scoring 80+ on Terrain typically enjoy wide economic moats — they earn returns well above their cost of capital and can sustain those returns for years. Companies scoring below 40 often compete in commodity-like markets with thin margins and limited pricing power.
將 Leadership (25% Weight) — Management Quality
Leadership assesses the people running the company. Insider ownership percentage and recent insider transactions reveal whether executives have meaningful "skin in the game." Capital allocation track record (acquisitions, buybacks, dividends, R&D investment) shows whether management deploys cash wisely. CEO communication quality is assessed from earnings call transcripts — looking for clarity, consistency, and transparency rather than vague optimism. Executive compensation structure reveals whether incentives are aligned with long-term shareholder value or short-term stock price targets. A high Leadership score indicates aligned, competent management. A low score often correlates with excessive executive compensation, insider selling, and poor capital allocation decisions.
法 Discipline (15% Weight) — Governance & Controls
Discipline evaluates the structural safeguards that prevent mismanagement. Board independence ratio (percentage of independent directors), CEO/Chair separation, share dilution trends (net shares outstanding over 3 years), and financial health scores — specifically the Altman Z-Score (bankruptcy risk) and Piotroski F-Score (fundamental strength) — comprise the key inputs. Companies scoring high on Discipline have independent boards, conservative share issuance, and strong fundamental health. Companies scoring low may have insider-dominated boards, excessive dilution from stock-based compensation, or deteriorating financial health metrics that signal operational stress.
How the Composite Score Works
Each factor receives a score from 0 to 100. The composite score is calculated as: (Purpose × 0.15) + (Climate × 0.15) + (Terrain × 0.30) + (Leadership × 0.25) + (Discipline × 0.15). This weighted sum produces a final score from 0 to 100, which maps to a recommendation: 80+ = Strong Buy, 65-79 = Buy, 50-64 = Watchlist, 35-49 = Caution, below 35 = Avoid. The system also computes an intrinsic value estimate using a blended DCF (Discounted Cash Flow) and relative valuation approach, then calculates the margin of safety between the current stock price and the estimated intrinsic value.
Limitations & Best Practices
No single framework can capture every nuance of a business. The Five Factors method works best for companies with at least 3 years of public financial data. It is less reliable for pre-revenue startups, SPACs, and recently IPO'd companies with limited track records. Use it as one input alongside other research — your own due diligence, industry expertise, and the Debate method for adversarial stress-testing.
