DuPont Model Analysis

The DuPont model decomposes return on equity (ROE) into three operating and capital-structure drivers:

ROE = Net Margin × Asset Turnover × Equity Multiplier

The comparison uses the latest two comparable annual periods available for the issuer, with reported statement amounts shown in HK$. Revenue and net income are income-statement flows; total assets and shareholders’ equity are year-end balance-sheet figures. This is a simplified year-end-balance DuPont comparison rather than an average-balance ROE calculation.

DuPont component Calculation FY2026 FY2025
Revenue Reported revenue HK$177.48M HK$162.46M
Net income Reported net income HK$4.23M HK$-13.28M
Total assets Year-end reported balance HK$247.05M HK$244.79M
Shareholders’ equity Year-end reported balance HK$177.74M HK$173.50M
Net margin Net income ÷ revenue 2.38% -8.17%
Asset turnover Revenue ÷ total assets 0.7184x 0.6637x
Equity multiplier Total assets ÷ shareholders’ equity 1.3900x 1.4109x
ROE Net margin × asset turnover × equity multiplier 2.38% -7.65%

2.5 FCFF DCF Valuation

FCFF DCF exception: WACC is outside the permitted 5.00%–30.00% model range. This post deliberately does not publish a mechanical enterprise value or implied per-share value on an unsuitable basis.

Buffett-inspired cash-quality checks not rated — FCFF DCF suitability or data-integrity condition not met
Lynch-inspired balance-and-growth checks not rated — FCFF DCF suitability or data-integrity condition not met

Data lineage: Yahoo Finance public market and reported-statement data; retrieval timestamp: 2026-08-18 17:18:06.374249 UTC; latest reported fiscal period: 2026-03-31 00:00:00. Financial institutions and REITs require sector-specific methods rather than a mechanical FCFF DCF. This is research and analysis only, not personalized financial advice.

2.7 Quantitative Factor Diagnostics

Model basis: Daily issuer USD excess returns are regressed in-sample using ordinary least squares on matching regional Fama–French factors. FF3 estimates market, size, and value loadings; FF5 adds profitability and investment. Coefficients are descriptive historical exposures, not predictions.

Estimation input Value
Regional factor set Asia Pacific ex Japan
Factor-return currency USD
Issuer-return basis USD adjusted total return
Estimation window 2025-08-20 to 2026-06-30
Aligned daily observations 210
Minimum observation requirement 120
Currency conversion for HK listings HKD adjusted close divided by daily USD/HKD close before simple daily return calculation

Fama–French Three-Factor and Five-Factor Results

Diagnostic FF3 FF5
Annualised alpha 66.29% 67.20%
Adjusted R² -0.01 -0.02
Annualised residual volatility 66.73% 66.70%
Factor loading (t-statistic) FF3 FF5
Market excess return (Mkt-RF) 0.29 (0.77) 0.33 (0.80)
Size (SMB) -0.09 (-0.16) -0.03 (-0.04)
Value (HML) 0.46 (0.87) 0.34 (0.59)
Profitability (RMW) NM -0.27 (-0.36)
Investment (CMA) NM 0.21 (0.25)

Definitions: Mkt-RF is the market return less the risk-free rate; SMB is small minus big; HML is high minus low book-to-market; RMW is robust minus weak profitability; CMA is conservative minus aggressive investment. Factor returns are sourced from the Kenneth R. French Data Library; issuer adjusted-return history is sourced from Yahoo Finance. For Hong Kong listings, adjusted HKD prices are converted into USD with daily USD/HKD closes before return calculation to match the USD regional factor basis. This is an in-sample historical regression; coefficients and t-statistics do not establish causation or predict future returns. This is research and analysis only, not personalized financial advice.
