Sinopec Oilfield Service's high P/E ratio is alarming considering the expected EPS drop. The current trading price may not hold due to likely falling earnings. The high P/E and forecasted earnings decline put shareholders' investments at high risk, and potential investors might be paying a hefty premium.

Sinopec's average ROE, impeded by high debt levels, reflects poorly on the firm's use of significant debt to amplify profits. A preferable situation would involve a firm achieving high ROE without resorting to debt.
