There are a few key trends to look for if we want to identify the next multi-bagger. Typically, we'll want to notice a trend of growing return on capital employed (ROCE) and alongside that, an expanding base of capital employed. Ultimately, this demonstrates that it's a business that is reinvesting profits at increasing rates of return. In light of that, when we looked at SPG (KOSDAQ:058610) and its ROCE trend, we weren't exactly thrilled.
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. The formula for this calculation on SPG is:
Return on Capital Employed = Earnings Before Interest and Tax (EBIT) ÷ (Total Assets - Current Liabilities)
0.056 = ₩15b ÷ (₩424b - ₩147b) (Based on the trailing twelve months to September 2025).
Therefore, SPG has an ROCE of 5.6%. In absolute terms, that's a low return and it also under-performs the Electrical industry average of 10.0%.

When we looked at the ROCE trend at SPG, we didn't gain much confidence. To be more specific, ROCE has fallen from 9.5% over the last five years. However it looks like SPG might be reinvesting for long term growth because while capital employed has increased, the company's sales haven't changed much in the last 12 months. It's worth keeping an eye on the company's earnings from here on to see if these investments do end up contributing to the bottom line.
Bringing it all together, while we're somewhat encouraged by SPG's reinvestment in its own business, we're aware that returns are shrinking. Investors must think there's better things to come because the stock has knocked it out of the park, delivering a 918% gain to shareholders who have held over the last five years. But if the trajectory of these underlying trends continue, we think the likelihood of it being a multi-bagger from here isn't high.
