Perfect Optronics Limited (HKG:8311) Shares May Have Slumped 44% But Getting In Cheap Is Still Unlikely

Perfect Optronics Limited (HKG:8311) shares have retraced a considerable 44% in the last month, reversing a fair amount of their solid recent performance. The drop over the last 30 days has capped off a tough year for shareholders, with the share price down 22% in that time.

Even after such a large drop in price, 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. However, investors might be overlooking a clear opportunity or potential setback if there is no rational basis for the P/S.

How Has Perfect Optronics Performed Recently?

For example, consider that Perfect Optronics' financial performance has been poor lately as its revenue has been in decline. 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 you like the company, you'd at least be hoping this is the case so that you could potentially pick up some stock while it's not quite in favour.

What Are Revenue Growth Metrics Telling Us About The P/S?

In order to justify its P/S ratio, Perfect Optronics would need to produce growth that's similar to the industry.

Retrospectively, the last year delivered a frustrating 59% decrease to the company's top line. This means it has also seen a slide in revenue over the longer-term as revenue is down 40% in total over the last three years. Therefore, it's fair to say the revenue growth recently has been undesirable for the company.

Comparing that to the industry, which is predicted to deliver 17% growth in the next 12 months, the company's downward momentum based on recent medium-term revenue results is a sobering picture.

In light of this, it's somewhat alarming that Perfect Optronics' P/S sits in line with the majority of other companies. Apparently many investors in the company are way less bearish than recent times would indicate and aren't willing to let go of their stock right now. There's a good chance existing shareholders are setting themselves up for future disappointment if the P/S falls to levels more in line with the recent negative growth rates.

The Bottom Line On Perfect Optronics' P/S

Perfect Optronics' plummeting stock price has brought its P/S back to a similar region as the rest of the industry. Generally, our preference is to limit the use of the price-to-sales ratio to establishing what the market thinks about the overall health of a company.

We find it unexpected that Perfect Optronics trades at a P/S ratio that is comparable to the rest of the industry, despite experiencing declining revenues during the medium-term, while the industry as a whole is expected to grow. When we see revenue heading backwards in the context of growing industry forecasts, it'd make sense to expect a possible share price decline on the horizon, sending the moderate P/S lower. If recent medium-term revenue trends continue, it will place shareholders' investments at risk and potential investors in danger of paying an unnecessary premium.
