What Are Revenue Growth Metrics Telling Us About The P/S?

The only time you'd be comfortable seeing a P/S like Zhejiang United Investment Holdings Group's is when the company's growth is tracking the industry closely.

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 7.3%. Even so, admirably revenue has lifted 110% 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 revenue over that time, even though it had some hiccups along the way.

Comparing that to the industry, which is only predicted to deliver 16% growth in the next 12 months, the company's momentum is stronger based on recent medium-term annualised revenue results.

We didn't quite envision Zhejiang United Investment Holdings Group's P/S sitting in line with the wider industry, considering the revenue growth over the last three-year is higher than the current industry outlook.
