If you're looking at a mature business that's past the growth phase, what are some of the underlying trends that pop up? Typically, we'll see the trend of both return on capital employed (ROCE) declining and this usually coincides with a decreasing amount of capital employed. Ultimately this means that the company is earning less per dollar invested and on top of that, it's shrinking its base of capital employed. On that note, looking into Petra Diamonds (LON:PDL), we weren't too upbeat about how things were going.
What is Return On Capital Employed (ROCE)?
Just to clarify if you're unsure, ROCE is a metric for evaluating how much pre-tax income (in percentage terms) a company earns on the capital invested in its business. Analysts use this formula to calculate it for Petra Diamonds:
Return on Capital Employed = Earnings Before Interest and Tax (EBIT) ÷ (Total Assets – Current Liabilities)
0.025 = US$24m ÷ (US$1.1b – US$118m) (Based on the trailing twelve months to June 2021).
Thus, Petra Diamonds has an ROCE of 2.5%. Ultimately, that's a low return and it under-performs the Metals and Mining industry average of 18%.

What Does the ROCE Trend For Petra Diamonds Tell Us?
There is reason to be cautious about Petra Diamonds, given the returns are trending downwards. To be more specific, the ROCE was 9.3% five years ago, but since then it has dropped noticeably. Meanwhile, capital employed in the business has stayed roughly the flat over the period. Since returns are falling and the business has the same amount of assets employed, this can suggest it's a mature business that hasn't had much growth in the last five years. So because these trends aren't typically conducive to creating a multi-bagger, we wouldn't hold our breath on Petra Diamonds becoming one if things continue as they have.
All in all, the lower returns from the same amount of capital employed aren't exactly signs of a compounding machine. We expect this has contributed to the stock plummeting 98% during the last five years. That being the case, unless the underlying trends revert to a more positive trajectory, we'd consider looking elsewhere.
