With a price-to-earnings (or "P/E") ratio of 38.3x Liquidity Services, Inc. (NASDAQ:LQDT) may be sending very bearish signals at the moment, given that almost half of all companies in the United States have P/E ratios under 16x and even P/E's lower than 9x are not unusual. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the highly elevated P/E.

Liquidity Services certainly has been doing a good job lately as it's been growing earnings more than most other companies. It seems that many are expecting the strong earnings performance to persist, which has raised the P/E. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

Is There Enough Growth For Liquidity Services?

The only time you'd be truly comfortable seeing a P/E as steep as Liquidity Services' is when the company's growth is on track to outshine the market decidedly.

If we review the last year of earnings growth, the company posted a terrific increase of 27%. Despite this strong recent growth, it's still struggling to catch up as its three-year EPS frustratingly shrank by 49% overall. Accordingly, shareholders would have felt downbeat about the medium-term rates of earnings growth.

Shifting to the future, estimates from the dual analysts covering the company suggest earnings should grow by 11% over the next year. Meanwhile, the rest of the market is forecast to expand by 14%, which is noticeably more attractive.

With this information, we find it concerning that Liquidity Services is trading at a P/E higher than the market. It seems most investors are hoping for a turnaround in the company's business prospects, but the analyst cohort is not so confident this will happen. Only the boldest would assume these prices are sustainable as this level of earnings growth is likely to weigh heavily on the share price eventually.

What We Can Learn From Liquidity Services' P/E?

Typically, we'd caution against reading too much into price-to-earnings ratios when settling on investment decisions, though it can reveal plenty about what other market participants think about the company.

Our examination of Liquidity Services' analyst forecasts revealed that its inferior earnings outlook isn't impacting its high P/E anywhere near as much as we would have predicted. When we see a weak earnings outlook with slower than market growth, we suspect the share price is at risk of declining, sending the high P/E lower. This places shareholders' investments at significant risk and potential investors in danger of paying an excessive premium.

Don't forget that there may be other risks.
