Sai MicroElectronics' high P/S ratio is concerning despite strong revenue growth, as it forecasts lower growth than the industry. The high P/S ratio and lower predicted future revenues could risk shareholders' investments and potential investors may pay an excessive premium.

Despite a strong balance sheet, Sai MicroElectronics posted an EBIT loss last year and burnt through CN¥1.1b of cash, hinting at a potential need to raise capital soon.

The positive trend in Sai MicroElectronics' share price over the years could indicate a favorable change in the company's business performance over time. While earnings per share have been declining, the focus appears to be on revenue growth instead.
