Ledman Optoelectronic's recent revenue performance may be seen as insufficient by the market, leading to a lower P/S ratio. The company's medium-term revenue trends are less appealing compared to the industry's one-year growth forecast of 36%, which may explain the lower P/S ratio. Investors may be accepting the low P/S ratio as they anticipate that future revenue will not provide any pleasant surprises.

Despite a recent share price drop, the company's long-term growth rate is seen as positive. However, concerns about potential slowdown in revenue growth and short-term problems are present. Warning signs with Ledman Optoelectronic should be considered in investment decisions.

Ledman Optoelectronic's lower P/S ratio could be due to its recent poor revenue performance and slower growth rates. Investors may anticipate these conditions persisting, thereby undervaluing the stock unless recent mid-term trends improve.
