With a median price-to-earnings (or "P/E") ratio of close to 17x in the United States, you could be forgiven for feeling indifferent about Option Care Health, Inc.'s (NASDAQ:OPCH) P/E ratio of 17.8x. Although, it's not wise to simply ignore the P/E without explanation as investors may be disregarding a distinct opportunity or a costly mistake.

Option Care Health certainly has been doing a good job lately as its earnings growth has been positive while most other companies have been seeing their earnings go backwards. It might be that many expect the strong earnings performance to deteriorate like the rest, which has kept the P/E from rising. If you like the company, you'd be hoping this isn't the case so that you could potentially pick up some stock while it's not quite in favour.

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

Option Care Health's P/E ratio would be typical for a company that's only expected to deliver moderate growth, and importantly, perform in line with the market.

If we review the last year of earnings growth, the company posted a terrific increase of 75%. The strong recent performance means it was also able to grow EPS by 3,078% in total over the last three years. So we can start by confirming that the company has done a great job of growing earnings over that time.

Shifting to the future, estimates from the eight analysts covering the company suggest earnings growth is heading into negative territory, declining 1.7% each year over the next three years. That's not great when the rest of the market is expected to grow by 9.9% each year.

In light of this, it's somewhat alarming that Option Care Health's P/E sits in line with the majority of other companies. Apparently many investors in the company reject the analyst cohort's pessimism and aren't willing to let go of their stock right now. Only the boldest would assume these prices are sustainable as these declining earnings are likely to weigh on the share price eventually.

What We Can Learn From Option Care Health's P/E?

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.

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