The Financial Rating evaluates six fundamental factors — discounted cash flow (DCF) valuation, return on equity (ROE), return on assets (ROA), debt-to-equity leverage (D/E), and relative price-to-earnings (P/E) and price-to-book (P/B) multiples — each scored 1–5. 2251.HK receives an overall rating of C. Strongest factors: P/B (4/5). Areas of concern: DCF (1/5), ROE (1/5), ROA (1/5), D/E (2/5), P/E (1/5).

OCF/NI: 0.60x

The Piotroski F-Score (2000) is a 9-point binary checklist — four profitability tests (positive ROA, positive cash flow, improving ROA, cash flow exceeding net income), three leverage tests (declining debt ratio, improving current ratio, no share dilution), and two efficiency tests (improving gross margin, improving asset turnover). Each pass scores 1 point. 2251.HK scores 4/9, indicating moderate financial health — some areas of strength offset by weaknesses in others. The Beneish M-Score (1999) is an 8-variable model that detects earnings manipulation by comparing year-over-year changes in receivables, gross margins, asset quality, sales growth, depreciation, SG&A, leverage, and accruals. Scores above −1.78 statistically resemble past manipulators. 2251.HK's score of -3.14 falls below this threshold, suggesting earnings are unlikely to be manipulated. The Ohlson O-Score (1980) is a 9-variable logistic regression that estimates bankruptcy probability using firm size, leverage, working capital, current ratio, profitability (ROA), cash flow coverage, negative equity flag, consecutive losses flag, and earnings trajectory. The raw score is converted to a probability via logistic transformation. 2251.HK's implied 0.1% bankruptcy probability is well within safe territory. Our Credit Rating model scores companies on five weighted components — solvency (30%), earning power (25%), leverage (20%), liquidity (15%), and cash flow quality (10%) — then blends the absolute score with sector and industry peer rankings. For companies with large buyback programs, equity is adjusted by adding back cumulative 5-year repurchases (capped at 80% of FCF generated) to avoid penalizing shareholder-friendly capital allocation. 2251.HK receives an estimated rating of BB+ (score: 49.5/100), with a deteriorating trend.

Valuation

Key valuation multiples comparing the stock's market price to its earnings, revenue, book value, and cash flows. Lower multiples may indicate relative undervaluation versus peers.

Graham Number
—
Equity-based multiples (P/E, P/B, P/FCF) compare the stock price to per-share fundamentals and are affected by capital structure. Enterprise value multiples (EV/EBITDA, EV/Revenue, EV/FCF) strip out debt and cash, making them more useful for cross-company comparisons regardless of how companies are financed. The Graham Number — √(22.5 × EPS × Book Value) — is Benjamin Graham's formula for the maximum price a defensive investor should pay. 2251.HK currently has negative earnings — the P/E ratio is not meaningful.

DuPont Decomposition (5-Factor)

The 5-factor DuPont framework breaks Return on Equity into its component drivers — tax efficiency, interest burden, operating profitability, asset utilization, and financial leverage — to reveal what truly drives shareholder returns.

ROE
-19.0%
The 5-factor DuPont identity decomposes ROE as: Tax Burden × Interest Burden × EBIT Margin × Asset Turnover × Equity Multiplier = ROE. This reveals whether returns are driven by operating performance, financial leverage, or tax efficiency — three very different sources of profitability. 2251.HK's ROE of -19.0% is driven by Asset Turnover (0.215), indicating efficient use of assets to generate revenue. A tax burden ratio of 0.96 indicates minimal tax leakage — the company retains over 90% of pre-tax earnings.

Graham-Dodd Adjusted Valuation

Our adaptation of Graham's growth formula (Fair P/E = 8.5 + 2g) from The Intelligent Investor. The classic version relies on analyst growth projections, which can be unreliable. This adjusted model substitutes the company's realized 3-year EPS CAGR — a backward-looking, verifiable measure of actual earnings power — grounding the valuation in demonstrated performance rather than forecasts.

Two adjustments we make, and why. Growth is capped at 15%. Graham defined g as expected growth over the next seven to ten years, not last year's rate. Across US companies since 1994 the median realized 7-year EPS growth is 5–8% regardless of how fast a company grew beforehand, and of 4,457 company-quarters that grew faster than 200%, none sustained it. Uncapped, the formula assigned fair multiples in the hundreds to companies that had never held that rate — and scored worse than simply reading the P/E. Capped, it carries real information. The verdict has three states, not two. Tested over 377,249 stock-months, this ratio only separates outcomes at its extremes: below 0.25 beat the universe by 1.3 points a year, above 3.0 lagged by 2.7, and everything in between sat inside a one-point band. Rather than call two-thirds of the market "undervalued" on a threshold of 1.0, we say Neutral where the model cannot tell — which is most of the time.
