If we want to find a stock that could multiply over the long term, what are the underlying trends we should look for? Ideally, a business will show two trends; firstly a growing return on capital employed (ROCE) and secondly, an increasing amount of capital employed. Ultimately, this demonstrates that it's a business that is reinvesting profits at increasing rates of return. So on that note, SigmaRoc (LON:SRC) looks quite promising in regards to its trends of return on capital.
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. To calculate this metric for SigmaRoc, this is the formula:
Return on Capital Employed = Earnings Before Interest and Tax (EBIT) ÷ (Total Assets - Current Liabilities)
0.057 = UK£104m ÷ (UK£2.2b - UK£401m) (Based on the trailing twelve months to June 2025).
Thus, SigmaRoc has an ROCE of 5.7%. On its own, that's a low figure but it's around the 6.8% average generated by the Basic Materials industry.

The Trend Of ROCE
While in absolute terms it isn't a high ROCE, it's promising to see that it has been moving in the right direction. The data shows that returns on capital have increased substantially over the last five years to 5.7%. The company is effectively making more money per dollar of capital used, and it's worth noting that the amount of capital has increased too, by 925%. So we're very much inspired by what we're seeing at SigmaRoc thanks to its ability to profitably reinvest capital.
The Bottom Line On SigmaRoc's ROCE
A company that is growing its returns on capital and can consistently reinvest in itself is a highly sought after trait, and that's what SigmaRoc has. Since the stock has returned a staggering 104% to shareholders over the last five years, it looks like investors are recognizing these changes. With that being said, we still think the promising fundamentals mean the company deserves some further due diligence.
