With a price-to-earnings (or "P/E") ratio of 28.1x CTS Corporation (NYSE:CTS) 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. However, the P/E might be quite high for a reason and it requires further investigation to determine if it's justified.

Recent times haven't been advantageous for CTS as its earnings have been falling quicker than most other companies. 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.

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

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

Taking a look back first, the company's earnings per share growth last year wasn't something to get excited about as it posted a disappointing decline of 5.5%. Even so, admirably EPS has lifted 31% in aggregate from three years ago, notwithstanding the last 12 months. So we can start by confirming that the company has generally done a very good job of growing earnings over that time, even though it had some hiccups along the way.

Shifting to the future, estimates from the dual analysts covering the company suggest earnings should grow by 28% over the next year. That's shaping up to be materially higher than the 12% growth forecast for the broader market.

With this information, we can see why CTS 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 Bottom Line On CTS' P/E

We'd say the price-to-earnings ratio's power isn't primarily as a valuation instrument but rather to gauge current investor sentiment and future expectations.

We've established that CTS maintains its high P/E on the strength of its forecast growth being higher than the wider market, as expected. Right now shareholders are comfortable with the P/E as they are quite confident future earnings aren't under threat. It's hard to see the share price falling strongly in the near future under these circumstances.

It is also worth noting that we have found 1 warning sign for CTS that you need to take into consideration.
