Revenues Not Telling The Story For Perfect Optronics Limited (HKG:8311) After Shares Rise 48%

Despite an already strong run, Perfect Optronics Limited (HKG:8311) shares have been powering on, with a gain of 48% in the last thirty days. This latest share price bounce rounds out a remarkable 350% gain over the last twelve months.

Following the firm bounce in price, when almost half of the companies in Hong Kong's Electronic industry have price-to-sales ratios (or "P/S") below 0.5x, you may consider Perfect Optronics as a stock probably not worth researching with its 2.2x P/S ratio. However, the P/S might be high for a reason and it requires further investigation to determine if it's justified.

What Does Perfect Optronics' Recent Performance Look Like?

For example, consider that Perfect Optronics' financial performance has been poor lately as its revenue has been in decline. Perhaps the market believes the company can do enough to outperform the rest of the industry in the near future, which is keeping the P/S ratio high. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

Is There Enough Revenue Growth Forecasted For Perfect Optronics?

The only time you'd be truly comfortable seeing a P/S as high as Perfect Optronics' is when the company's growth is on track to outshine 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 19%. This means it has also seen a slide in revenue over the longer-term as revenue is down 82% in total over the last three years. So unfortunately, we have to acknowledge that the company has not done a great job of growing revenue over that time.

In contrast to the company, the rest of the industry is expected to grow by 18% over the next year, which really puts the company's recent medium-term revenue decline into perspective.

With this information, we find it concerning that Perfect Optronics is trading at a P/S higher than the industry. It seems most investors are ignoring the recent poor growth rate and are hoping for a turnaround in the company's business prospects. Only the boldest would assume these prices are sustainable as a continuation of recent revenue trends is likely to weigh heavily on the share price eventually.

The Key Takeaway

The large bounce in Perfect Optronics' shares has lifted the company's P/S handsomely. While the price-to-sales ratio shouldn't be the defining factor in whether you buy a stock or not, it's quite a capable barometer of revenue expectations.

We've established that Perfect Optronics currently trades on a much higher than expected P/S since its recent revenues have been in decline over the medium-term. Right now we aren't comfortable with the high P/S as this revenue performance is highly unlikely to support such positive sentiment for long. Should recent medium-term revenue trends persist, it would pose a significant risk to existing shareholders' investments and prospective investors will have a hard time accepting the current value of the stock.
