If we want to find a stock that could multiply over the long term, what are the underlying trends we should look for? Typically, we'll want to notice a trend of growing return on capital employed (ROCE) and alongside that, an expanding base of capital employed. Put simply, these types of businesses are compounding machines, meaning they are continually reinvesting their earnings at ever-higher rates of return. So when we looked at Oxford Instruments (LON:OXIG) and its trend of ROCE, we really liked what we saw.
Understanding 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 Oxford Instruments:
Return on Capital Employed = Earnings Before Interest and Tax (EBIT) ÷ (Total Assets - Current Liabilities)
0.16 = UK£38m ÷ (UK£411m - UK£164m) (Based on the trailing twelve months to September 2020).
Therefore, Oxford Instruments has an ROCE of 16%. On its own, that's a standard return, however it's much better than the 7.2% generated by the Electronic industry.

So How Is Oxford Instruments' ROCE Trending?
You'd find it hard not to be impressed with the ROCE trend at Oxford Instruments. The figures show that over the last five years, returns on capital have grown by 146%. That's a very favorable trend because this means that the company is earning more per dollar of capital that's being employed. Speaking of capital employed, the company is actually utilizing 26% less than it was five years ago, which can be indicative of a business that's improving its efficiency. If this trend continues, the business might be getting more efficient but it's shrinking in terms of total assets.
On a side note, we noticed that the improvement in ROCE appears to be partly fueled by an increase in current liabilities. Essentially the business now has suppliers or short-term creditors funding about 40% of its operations, which isn't ideal. It's worth keeping an eye on this because as the percentage of current liabilities to total assets increases, some aspects of risk also increase.
