Finding a business that has the potential to grow substantially is not easy, but it is possible if we look at a few key financial metrics. Amongst other things, we'll want to see two things; firstly, a growing return on capital employed (ROCE) and secondly, an expansion in the company's amount 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 MIXI (TSE:2121) and its trend of ROCE, we really liked what we saw.
Return On Capital Employed (ROCE): What Is It?
For those who don't know, ROCE is a measure of a company's yearly pre-tax profit (its return), relative to the capital employed in the business. To calculate this metric for MIXI, this is the formula:
Return on Capital Employed = Earnings Before Interest and Tax (EBIT) ÷ (Total Assets - Current Liabilities)
0.14 = JP¥27b ÷ (JP¥226b - JP¥31b) (Based on the trailing twelve months to March 2025).
Therefore, MIXI has an ROCE of 14%. On its own, that's a standard return, however it's much better than the 11% generated by the Entertainment industry.

What The Trend Of ROCE Can Tell Us
MIXI has not disappointed with their ROCE growth. The figures show that over the last five years, ROCE has grown 49% whilst employing roughly the same amount of capital. So our take on this is that the business has increased efficiencies to generate these higher returns, all the while not needing to make any additional investments. The company is doing well in that sense, and it's worth investigating what the management team has planned for long term growth prospects.

In Conclusion...
To bring it all together, MIXI has done well to increase the returns it's generating from its capital employed. Since the stock has returned a staggering 125% to shareholders over the last five years, it looks like investors are recognizing these changes. So given the stock has proven it has promising trends, it's worth researching the company further to see if these trends are likely to persist.
