There are a few key trends to look for if we want to identify the next multi-bagger. Firstly, we'd want to identify a growing return on capital employed (ROCE) and then alongside that, an ever-increasing base of capital employed. Basically this means that a company has profitable initiatives that it can continue to reinvest in, which is a trait of a compounding machine. So when we looked at Nephros (NASDAQ:NEPH) and its trend of ROCE, we really liked what we saw.
For those that aren't sure what ROCE is, it measures the amount of pre-tax profits a company can generate from the capital employed in its business. Analysts use this formula to calculate it for Nephros:
Return on Capital Employed = Earnings Before Interest and Tax (EBIT) ÷ (Total Assets - Current Liabilities)
0.13 = US$1.4m ÷ (US$13m - US$2.5m) (Based on the trailing twelve months to September 2025).
Thus, Nephros has an ROCE of 13%. In absolute terms, that's a satisfactory return, but compared to the Machinery industry average of 11% it's much better.

We're delighted to see that Nephros is reaping rewards from its investments and has now broken into profitability. The company was generating losses five years ago, but has managed to turn it around and as we saw earlier is now earning 13%, which is always encouraging. On top of that, what's interesting is that the amount of capital being employed has remained steady, so the business hasn't needed to put any additional money to work to generate these higher returns. With no noticeable increase in capital employed, it's worth knowing what the company plans on doing going forward in regards to reinvesting and growing the business. So if you're looking for high growth, you'll want to see a business's capital employed also increasing.
In summary, we're delighted to see that Nephros has been able to increase efficiencies and earn higher rates of return on the same amount of capital. And since the stock has fallen 35% over the last five years, there might be an opportunity here. With that in mind, we believe the promising trends warrant this stock for further investigation.
