SolarMax Technology, Inc. (NASDAQ:SMXT) shareholders are no doubt pleased to see that the share price has bounced 29% in the last month, although it is still struggling to make up recently lost ground. While recent buyers may be laughing, long-term holders might not be as pleased since the recent gain only brings the stock back to where it started a year ago.

Although its price has surged higher, you could still be forgiven for feeling indifferent about SolarMax Technology's P/S ratio of 1.7x, since the median price-to-sales (or "P/S") ratio for the Electrical industry in the United States is also close to 1.9x. However, investors might be overlooking a clear opportunity or potential setback if there is no rational basis for the P/S.

How SolarMax Technology Has Been Performing

For example, consider that SolarMax Technology's financial performance has been poor lately as its revenue has been in decline. It might be that many expect the company to put the disappointing revenue performance behind them over the coming period, which has kept the P/S from falling. If not, then existing shareholders may be a little nervous about the viability of the share price.

Is There Some Revenue Growth Forecasted For SolarMax Technology?

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

Taking a look back first, the company's revenue growth last year wasn't something to get excited about as it posted a disappointing decline of 49%. As a result, revenue from three years ago have also fallen 24% overall. So unfortunately, we have to acknowledge that the company has not done a great job of growing revenue over that time.

Comparing that to the industry, which is predicted to deliver 24% growth in the next 12 months, the company's downward momentum based on recent medium-term revenue results is a sobering picture.

With this information, we find it concerning that SolarMax Technology is trading at a fairly similar P/S compared to the industry. Apparently many investors in the company are way less bearish than recent times would indicate and aren't willing to let go of their stock right now. There's a good chance existing shareholders are setting themselves up for future disappointment if the P/S falls to levels more in line with the recent negative growth rates.

What We Can Learn From SolarMax Technology's P/S?

SolarMax Technology's stock has a lot of momentum behind it lately, which has brought its P/S level with the rest of the industry. It's argued the price-to-sales ratio is an inferior measure of value within certain industries, but it can be a powerful business sentiment indicator.

We find it unexpected that SolarMax Technology trades at a P/S ratio that is comparable to the rest of the industry, despite experiencing declining revenues during the medium-term, while the industry as a whole is expected to grow. When we see revenue heading backwards in the context of growing industry forecasts, it'd make sense to expect a possible share price decline on the horizon, sending the moderate P/S lower. If recent medium-term revenue trends continue, it will place shareholders' investments at risk and potential investors in danger of paying an unnecessary premium.
