Perfect Optronics Limited's (HKG:8311) 26% Dip Still Leaving Some Shareholders Feeling Restless Over Its P/SRatio

Perfect Optronics Limited (HKG:8311) shareholders won't be pleased to see that the share price has had a very rough month, dropping 26% and undoing the prior period's positive performance. Instead of being rewarded, shareholders who have already held through the last twelve months are now sitting on a 49% share price drop.

In spite of the heavy fall in price, there still wouldn't be many who think Perfect Optronics' price-to-sales (or "P/S") ratio of 0.3x is worth a mention when it essentially matches the median P/S in Hong Kong's Electronic industry. 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 Perfect Optronics Has Been Performing

As an illustration, revenue has deteriorated at Perfect Optronics over the last year, which is not ideal at all. Perhaps investors believe the recent revenue performance is enough to keep in line with the industry, which is keeping the P/S from dropping off. If not, then existing shareholders may be a little nervous about the viability of the share price.

Do Revenue Forecasts Match The P/S Ratio?

In order to justify its P/S ratio, Perfect Optronics would need to produce growth that's similar to 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 30%. The last three years don't look nice either as the company has shrunk revenue by 72% in aggregate. Therefore, it's fair to say the revenue growth recently has been undesirable for the company.

In contrast to the company, the rest of the industry is expected to grow by 23% over the next year, which really puts the company's recent medium-term revenue decline into perspective.

With this in mind, we find it worrying that Perfect Optronics' P/S exceeds that of its industry peers. 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 Key Takeaway

Perfect Optronics' plummeting stock price has brought its P/S back to a similar region as the rest of the industry. Using the price-to-sales ratio alone to determine if you should sell your stock isn't sensible, however it can be a practical guide to the company's future prospects.

The fact that Perfect Optronics currently trades at a P/S on par with the rest of the industry is surprising to us since its recent revenues have been in decline over the medium-term, all while the industry is set 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. Unless the recent medium-term conditions improve markedly, investors will have a hard time accepting the share price as fair value.
