LifeVantage Corporation (NASDAQ:LFVN) shares have continued their recent momentum with a 31% gain in the last month alone. The last month tops off a massive increase of 183% in the last year.

Following the firm bounce in price, given close to half the companies in the United States have price-to-earnings ratios (or "P/E's") below 18x, you may consider LifeVantage as a stock to avoid entirely with its 53.7x P/E ratio. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the highly elevated P/E.

Recent times have been advantageous for LifeVantage as its earnings have been rising faster than most other companies. It seems that many are expecting the strong earnings performance to persist, which has raised the P/E. If not, then existing shareholders might be a little nervous about the viability of the share price.

Keen to find out how analysts think LifeVantage's future stacks up against the industry? In that case, our free report is a great place to start.

What Are Growth Metrics Telling Us About The High P/E?

LifeVantage's P/E ratio would be typical for a company that's expected to deliver very strong growth, and importantly, perform much better than the market.

If we review the last year of earnings growth, the company posted a terrific increase of 64%. Despite this strong recent growth, it's still struggling to catch up as its three-year EPS frustratingly shrank by 67% overall. Accordingly, shareholders would have felt downbeat about the medium-term rates of earnings growth.

Looking ahead now, EPS is anticipated to climb by 111% during the coming year according to the two analysts following the company. That's shaping up to be materially higher than the 15% growth forecast for the broader market.

With this information, we can see why LifeVantage is trading at such a high P/E compared to the market. Apparently shareholders aren't keen to offload something that is potentially eyeing a more prosperous future.

The Key Takeaway

LifeVantage's P/E is flying high just like its stock has during the last month. Using the price-to-earnings 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.

As we suspected, our examination of LifeVantage's analyst forecasts revealed that its superior earnings outlook is contributing to its high P/E. At this stage investors feel the potential for a deterioration in earnings isn't great enough to justify a lower P/E ratio. Unless these conditions change, they will continue to provide strong support to the share price.
