Perfect Optronics Limited (HKG:8311) shares have continued their recent momentum with a 25% gain in the last month alone. But the last month did very little to improve the 56% share price decline over the last year.

Although its price has surged higher, there still wouldn't be many who think Perfect Optronics' price-to-sales (or "P/S") ratio of 0.7x is worth a mention when the median P/S in Hong Kong's Electronic industry is similar at about 0.4x. Although, it's not wise to simply ignore the P/S without explanation as investors may be disregarding a distinct opportunity or a costly mistake.

How Has Perfect Optronics Performed Recently?

For instance, Perfect Optronics' receding revenue in recent times would have to be some food for thought. One possibility is that the P/S is moderate because investors think the company might still do enough to be in line with the broader industry in the near future. If not, then existing shareholders may be a little nervous about the viability of the share price.

How Is Perfect Optronics' Revenue Growth Trending?

Perfect Optronics' P/S ratio would be typical for a company that's only expected to deliver moderate growth, and importantly, perform in line with the industry.

Taking a look back first, the company's revenue growth last year wasn't something to get excited about as it posted a disappointing decline of 66%. This has soured the latest three-year period, which nevertheless managed to deliver a decent 7.1% overall rise in revenue. So we can start by confirming that the company has generally done a good job of growing revenue over that time, even though it had some hiccups along the way.

Comparing the recent medium-term revenue trends against the industry's one-year growth forecast of 12% shows it's noticeably less attractive.

With this in mind, we find it intriguing that Perfect Optronics' P/S is comparable to that of its industry peers. It seems most investors are ignoring the fairly limited recent growth rates and are willing to pay up for exposure to the stock. Maintaining these prices will be difficult to achieve as a continuation of recent revenue trends is likely to weigh down the shares eventually.

The Final Word

Perfect Optronics' stock has a lot of momentum behind it lately, which has brought its P/S level with the rest of the industry. Typically, we'd caution against reading too much into price-to-sales ratios when settling on investment decisions, though it can reveal plenty about what other market participants think about the company.

Our examination of Perfect Optronics revealed its poor three-year revenue trends aren't resulting in a lower P/S as per our expectations, given they look worse than current industry outlook. When we see weak revenue with slower than industry growth, we suspect the share price is at risk of declining, bringing the P/S back in line with expectations. Unless there is a significant improvement in the company's medium-term performance, it will be difficult to prevent the P/S ratio from declining to a more reasonable level.
