LivePerson, Inc. (NASDAQ:LPSN) shares have had a horrible month, losing 26% after a relatively good period beforehand. For any long-term shareholders, the last month ends a year to forget by locking in a 69% share price decline.

Following the heavy fall in price, LivePerson's price-to-sales (or "P/S") ratio of 0.2x might make it look like a strong buy right now compared to the wider Software industry in the United States, where around half of the companies have P/S ratios above 5.1x and even P/S above 12x are quite common. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the highly reduced P/S.

What Does LivePerson's Recent Performance Look Like?

While the industry has experienced revenue growth lately, LivePerson's revenue has gone into reverse gear, which is not great. It seems that many are expecting the poor revenue performance to persist, which has repressed the P/S ratio. 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?

LivePerson's P/S ratio would be typical for a company that's expected to deliver very poor growth or even falling revenue, and importantly, perform much worse than the industry.

Retrospectively, the last year delivered a frustrating 22% decrease to the company's top line. As a result, revenue from three years ago have also fallen 25% overall. Accordingly, shareholders would have felt downbeat about the medium-term rates of revenue growth.

Looking ahead now, revenue is anticipated to slump, contracting by 14% during the coming year according to the six analysts following the company. Meanwhile, the broader industry is forecast to expand by 25%, which paints a poor picture.

In light of this, it's understandable that LivePerson's P/S would sit below the majority of other companies. However, shrinking revenues are unlikely to lead to a stable P/S over the longer term. There's potential for the P/S to fall to even lower levels if the company doesn't improve its top-line growth.

The Bottom Line On LivePerson's P/S

LivePerson's P/S looks about as weak as its stock price lately. Typically, we'd caution against reading too much into price-to-sales ratios when settling on investment decisions, though it can reveal plenty about what other market participants think about the company.

It's clear to see that LivePerson maintains its low P/S on the weakness of its forecast for sliding revenue, as expected. As other companies in the industry are forecasting revenue growth, LivePerson's poor outlook justifies its low P/S ratio. Unless there's material change, it's hard to envision a situation where the stock price will rise drastically.
