Those holding Wisesoft Co., Ltd. (SZSE:002253) shares would be relieved that the share price has rebounded 48% in the last thirty days, but it needs to keep going to repair the recent damage it has caused to investor portfolios. Unfortunately, the gains of the last month did little to right the losses of the last year with the stock still down 20% over that time.

Following the firm bounce in price, you could be forgiven for thinking Wisesoft is a stock to steer clear of with a price-to-sales ratios (or "P/S") of 14.4x, considering almost half the companies in China's Software industry have P/S ratios below 5.2x. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the highly elevated P/S.

What Does Wisesoft's P/S Mean For Shareholders?

For example, consider that Wisesoft's financial performance has been poor lately as its revenue has been in decline. It might be that many expect the company to still outplay most other companies over the coming period, which has kept the P/S from collapsing. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

Do Revenue Forecasts Match The High P/S Ratio?

There's an inherent assumption that a company should far outperform the industry for P/S ratios like Wisesoft's to be considered reasonable.

In reviewing the last year of financials, we were disheartened to see the company's revenues fell to the tune of 21%. This means it has also seen a slide in revenue over the longer-term as revenue is down 46% in total over the last three years. Therefore, it's fair to say the revenue growth recently has been undesirable for the company.

Weighing that medium-term revenue trajectory against the broader industry's one-year forecast for expansion of 33% shows it's an unpleasant look.

With this in mind, we find it worrying that Wisesoft's P/S exceeds that of its industry peers. 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

Wisesoft's P/S has grown nicely over the last month thanks to a handy boost in the share price. 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.

Our examination of Wisesoft revealed its shrinking revenue over the medium-term isn't resulting in a P/S as low as we expected, given the industry is set to grow. 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. If recent medium-term revenue trends continue, it will place shareholders' investments at significant risk and potential investors in danger of paying an excessive premium.
