Subdued Growth No Barrier To OSI Systems, Inc. (NASDAQ:OSIS) With Shares Advancing 29%

OSI Systems, Inc. (NASDAQ:OSIS) shareholders would be excited to see that the share price has had a great month, posting a 29% gain and recovering from prior weakness. The last 30 days bring the annual gain to a very sharp 66%.

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 17x, you may consider OSI Systems as a stock to avoid entirely with its 26.7x 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.

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

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

Taking a look back first, we see that the company managed to grow earnings per share by a handy 13% last year. The latest three year period has also seen an excellent 39% overall rise in EPS, aided somewhat by its short-term performance. Therefore, it's fair to say the earnings growth recently has been superb for the company.

Turning to the outlook, the next year should generate growth of 8.9% as estimated by the seven analysts watching the company. That's shaping up to be materially lower than the 13% growth forecast for the broader market.

With this information, we find it concerning that OSI Systems is trading at a P/E higher than the market. Apparently many investors in the company are way more bullish than analysts indicate and aren't willing to let go of their stock at any price. 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.

The Final Word

Shares in OSI Systems have built up some good momentum lately, which has really inflated its 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.

We've established that OSI Systems currently trades on a much higher than expected P/E since its forecast growth is lower than the wider market. 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. Unless these conditions improve markedly, it's very challenging to accept these prices as being reasonable.

It's always necessary to consider the ever-present spectre of investment risk. We've identified 1 warning sign with OSI Systems, and understanding should be part of your investment process.

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.
