When close to half the companies in the United States have price-to-earnings ratios (or "P/E's") below 16x, you may consider Endava plc (NYSE:DAVA) as a stock to avoid entirely with its 27.8x P/E ratio. Although, it's not wise to just take the P/E at face value as there may be an explanation why it's so lofty.

With earnings that are retreating more than the market's of late, Endava has been very sluggish. It might be that many expect the dismal earnings performance to recover substantially, which has kept the P/E from collapsing. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

Does Growth Match The High P/E?

In order to justify its P/E ratio, Endava would need to produce outstanding growth well in excess of the market.

Retrospectively, the last year delivered a frustrating 58% decrease to the company's bottom line. This has soured the latest three-year period, which nevertheless managed to deliver a decent 18% overall rise in EPS. Accordingly, while they would have preferred to keep the run going, shareholders would be roughly satisfied with the medium-term rates of earnings growth.

Turning to the outlook, the next year should bring diminished returns, with earnings decreasing 12% as estimated by the analysts watching the company. With the market predicted to deliver 12% growth , that's a disappointing outcome.

In light of this, it's alarming that Endava's P/E sits above the majority of other companies. 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 these declining earnings are likely to weigh heavily on the share price eventually.

The Key Takeaway

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 Endava's analyst forecasts revealed that its outlook for shrinking earnings isn't impacting its high P/E anywhere near as much as we would have predicted. When we see a poor outlook with earnings heading backwards, we suspect the share price is at risk of declining, sending the high P/E lower. Unless these conditions improve markedly, it's very challenging to accept these prices as being reasonable.

Before you settle on your opinion, we've discovered 2 warning signs for Endava that you should be aware of.

Of course, you might find a fantastic investment by looking at a few good candidates. So take a peek at this free list of companies with a strong growth track record, trading on a low P/E.
