There are a few key trends to look for if we want to identify the next multi-bagger. Firstly, we'll want to see a proven return on capital employed (ROCE) that is increasing, and secondly, an expanding 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. That's why when we briefly looked at Saia's (NASDAQ:SAIA) ROCE trend, we were pretty happy with 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. To calculate this metric for Saia, this is the formula:
Return on Capital Employed = Earnings Before Interest and Tax (EBIT) ÷ (Total Assets - Current Liabilities)
0.12 = US$394m ÷ (US$3.5b - US$296m) (Based on the trailing twelve months to September 2025).
Therefore, Saia has an ROCE of 12%. On its own, that's a standard return, however it's much better than the 9.7% generated by the Transportation industry.

In the above chart we have measured Saia's prior ROCE against its prior performance, but the future is arguably more important. If you'd like, you can check out the forecasts from the analysts covering Saia for free.
While the returns on capital are good, they haven't moved much. The company has consistently earned 12% for the last five years, and the capital employed within the business has risen 148% in that time. Since 12% is a moderate ROCE though, it's good to see a business can continue to reinvest at these decent rates of return. Over long periods of time, returns like these might not be too exciting, but with consistency they can pay off in terms of share price returns.
The main thing to remember is that Saia has proven its ability to continually reinvest at respectable rates of return. Therefore it's no surprise that shareholders have earned a respectable 69% return if they held over the last five years. So while the positive underlying trends may be accounted for by investors, we still think this stock is worth looking into further.
