Raytron TechnologyLtd's ROE, despite seeming unattractive, is above industry average and has spurred company growth. High earnings retention and a position in a high growth industry also contribute to this growth. The company's performance is commendable, with significant earnings growth supported by a respectable ROE and a high reinvestment rate.

Investors' belief in the company's continued market outperformance likely explains its high P/E ratio. The potential for earnings deterioration doesn't seem significant enough to warrant a lower P/E ratio.

Despite apprehension about Raytron Technology's high P/E ratio and low forecast growth, bullish sentiment is high among investors. This unsustainable optimism draws potential risk for shareholders and potential overvaluation for new investors.

Despite Raytron's ROE not being high, it significantly surpasses the industry average, contributing to its earnings growth. With high reinvestment & strong past performance, expectations are for continued growth.

Lower returns on investments, despite growth reinvestment and revenue increase, have led to a reduced company's ROCE and stock price decline in the past few years.
