Despite an already strong run, Quantum Corporation (NASDAQ:QMCO) shares have been powering on, with a gain of 82% in the last thirty days. The last 30 days bring the annual gain to a very sharp 47%.

Although its price has surged higher, Quantum may still be sending bullish signals at the moment with its price-to-sales (or "P/S") ratio of 0.2x, since almost half of all companies in the Tech industry in the United States have P/S ratios greater than 1x and even P/S higher than 4x are not unusual. Although, it's not wise to just take the P/S at face value as there may be an explanation why it's limited.

How Quantum Has Been Performing

Quantum hasn't been tracking well recently as its declining revenue compares poorly to other companies, which have seen some growth in their revenues on average. The P/S ratio is probably low because investors think this poor revenue performance isn't going to get any better. If this is the case, then existing shareholders will probably struggle to get excited about the future direction of the share price.

Do Revenue Forecasts Match The Low P/S Ratio?

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

Retrospectively, the last year delivered a frustrating 28% decrease to the company's top line. As a result, revenue from three years ago have also fallen 23% overall. Therefore, it's fair to say the revenue growth recently has been undesirable for the company.

Turning to the outlook, the next year should bring diminished returns, with revenue decreasing 2.5% as estimated by the dual analysts watching the company. Meanwhile, the broader industry is forecast to expand by 6.6%, which paints a poor picture.

With this information, we are not surprised that Quantum is trading at a P/S lower than the industry. However, shrinking revenues are unlikely to lead to a stable P/S over the longer term. Even just maintaining these prices could be difficult to achieve as the weak outlook is weighing down the shares.

The Key Takeaway

Despite Quantum's share price climbing recently, its P/S still lags most other companies. We'd say the price-to-sales ratio's power isn't primarily as a valuation instrument but rather to gauge current investor sentiment and future expectations.

It's clear to see that Quantum maintains its low P/S on the weakness of its forecast for sliding revenue, as expected. Right now shareholders are accepting the low P/S as they concede future revenue probably won't provide any pleasant surprises. It's hard to see the share price rising strongly in the near future under these circumstances.
