With a median price-to-sales (or "P/S") ratio of close to 1x in the Insurance industry in the United States, you could be forgiven for feeling indifferent about Mercury General Corporation's (NYSE:MCY) P/S ratio of 0.7x. Although, it's not wise to simply ignore the P/S without explanation as investors may be disregarding a distinct opportunity or a costly mistake.

What Does Mercury General's Recent Performance Look Like?

Mercury General's revenue growth of late has been pretty similar to most other companies. It seems that many are expecting the mediocre revenue performance to persist, which has held the P/S ratio back. Those who are bullish on Mercury General will be hoping that revenue performance can pick up, so that they can pick up the stock at a slightly lower valuation.

How Is Mercury General's Revenue Growth Trending?

In order to justify its P/S ratio, Mercury General would need to produce growth that's similar to the industry.

Retrospectively, the last year delivered an exceptional 22% gain to the company's top line. The latest three year period has also seen a 18% overall rise in revenue, aided extensively by its short-term performance. So we can start by confirming that the company has actually done a good job of growing revenue over that time.

Turning to the outlook, the next year should generate growth of 15% as estimated by the one analyst watching the company. That's shaping up to be materially higher than the 6.2% growth forecast for the broader industry.

In light of this, it's curious that Mercury General's P/S sits in line with the majority of other companies. Apparently some shareholders are skeptical of the forecasts and have been accepting lower selling prices.

What We Can Learn From Mercury General's P/S?

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

We've established that Mercury General currently trades on a lower than expected P/S since its forecasted revenue growth is higher than the wider industry. There could be some risks that the market is pricing in, which is preventing the P/S ratio from matching the positive outlook. It appears some are indeed anticipating revenue instability, because these conditions should normally provide a boost to the share price.
