Quality and financial health
Financial health is average - CLWT passes 6 of the nine Piotroski tests, which passes the Sunday Scan's "6 or more" rule. The Financials tab on the Quote page shows which tests fail. The GLS Moat score is low at 2.7 out of 10, which says the ten-year record of revenue, earnings, margins and returns on capital has been inconsistent - growth and shocks rather than steady compounding.
Returns on capital are thin or negative - ROIC 1.0%, ROE 1.0%, ROA 0.7% - with debt at 0.02 times equity and negative free cash flow.
Euro Tech Holdings Company Limited pays no dividend, so the DDM model does not apply and a covered-call holder earns only the premium and any price gain. Revenue comes mainly from The PRC 98%, Others 2% (fiscal year FY2016).
Institutional ownership scores 1/10, insider activity 5/10 and Congressional trading 5/10 on the GLS smart-money scales.
| Piotroski F-score | 6 / 9 | ROIC | 1.0% |
|---|---|---|---|
| GLS Moat | 2.7 / 10 | ROE | 1.0% |
| Debt / equity | 0.02 | ROA | 0.7% |
| Free-cash-flow yield | 0.0% | Payout ratio | 0% |
| Institutions | 1 / 10 | Insiders · Congress | 5 · 5 / 10 |
