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 NiSource Inc.'s (NYSE:NI) P/E ratio of 16.3x. 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.
NiSource has been struggling lately as its earnings have declined faster than most other companies. It might be that many expect the dismal earnings performance to revert back to market averages soon, which has kept the P/E from falling. If you still like the company, you'd want its earnings trajectory to turn around before making any decisions. If not, then existing shareholders may be a little nervous about the viability of the share price.

What Are Growth Metrics Telling Us About The P/E?
In order to justify its P/E ratio, NiSource would need to produce growth that's similar to the market.
Retrospectively, the last year delivered a frustrating 2.6% decrease to the company's bottom line. At least EPS has managed not to go completely backwards from three years ago in aggregate, thanks to the earlier period of growth. Accordingly, shareholders probably wouldn't have been overly satisfied with the unstable medium-term growth rates.
Shifting to the future, estimates from the nine analysts covering the company suggest earnings should grow by 6.4% per year over the next three years. That's shaping up to be materially lower than the 13% each year growth forecast for the broader market.
With this information, we find it interesting that NiSource is trading at a fairly similar P/E to the market. Apparently many investors in the company are less bearish than analysts indicate and aren't willing to let go of their stock right now. Maintaining these prices will be difficult to achieve as this level of earnings growth is likely to weigh down the shares eventually.
The Key Takeaway
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 NiSource currently trades on a 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 moderate P/E lower. Unless these conditions improve, it's challenging to accept these prices as being reasonable.
