AJ Lucas Group Limited (ASX:AJL) shares have had a really impressive month, gaining 71% after a shaky period beforehand. Unfortunately, despite the strong performance over the last month, the full year gain of 9.1% isn't as attractive.

In spite of the firm bounce in price, when close to half the companies operating in Australia's Construction industry have price-to-sales ratios (or "P/S") above 0.6x, you may still consider AJ Lucas Group as an enticing stock to check out with its 0.1x P/S ratio. Although, it's not wise to just take the P/S at face value as there may be an explanation why it's limited.

What Does AJ Lucas Group's Recent Performance Look Like?

For example, consider that AJ Lucas Group's financial performance has been pretty ordinary lately as revenue growth is non-existent. One possibility is that the P/S is low because investors think this benign revenue growth rate will likely underperform the broader industry in the near future. If you like the company, you'd be hoping this isn't the case so that you could potentially pick up some stock while it's out of favour.

How Is AJ Lucas Group's Revenue Growth Trending?

The only time you'd be truly comfortable seeing a P/S as low as AJ Lucas Group's is when the company's growth is on track to lag the industry.

Retrospectively, the last year delivered virtually the same number to the company's top line as the year before. However, a few strong years before that means that it was still able to grow revenue by an impressive 43% in total over the last three years. Therefore, it's fair to say the revenue growth recently has been great for the company, but investors will want to ask why it has slowed to such an extent.

This is in contrast to the rest of the industry, which is expected to grow by 10% over the next year, materially lower than the company's recent medium-term annualised growth rates.

With this information, we find it odd that AJ Lucas Group is trading at a P/S lower than the industry. Apparently some shareholders believe the recent performance has exceeded its limits and have been accepting significantly lower selling prices.

What We Can Learn From AJ Lucas Group's P/S?

Despite AJ Lucas Group's share price climbing recently, its P/S still lags most other companies. Generally, our preference is to limit the use of the price-to-sales ratio to establishing what the market thinks about the overall health of a company.

Our examination of AJ Lucas Group revealed its three-year revenue trends aren't boosting its P/S anywhere near as much as we would have predicted, given they look better than current industry expectations. Potential investors that are sceptical over continued revenue performance may be preventing the P/S ratio from matching previous strong performance. While recent revenue trends over the past medium-term suggest that the risk of a price decline is low, investors appear to perceive a likelihood of revenue fluctuations in the future.
