Institutional Asymmetry and the DuPont Transmission: Deconstructing Corporate Return Sustainability of ASEAN Capital Markets
This study analyzes corporate return sustainability across ASEAN capital markets from 2021 to 2025 using an expanded DuPont framework, revealing that profit margins are the primary driver of returns while highlighting a leverage paradox where debt boosts short-term gains but increases vulnerability to high interest rates.

In the world of business, investors and regulators often look at a single number to judge how well a company is doing: the return on equity. This figure tells them how much profit a company generates for every dollar of money its owners have invested. For decades, financial experts have used a method called DuPont analysis to break this single number down into three distinct parts, much like a doctor examining a patient's vital signs separately rather than just checking a fever. The first part measures how much profit a company keeps from every sale it makes, known as the profit margin. The second part looks at how efficiently the company uses its physical assets, such as factories and inventory, to generate sales. The third part examines how much debt the company uses to fund its operations. While these tools are standard, a new study suggests that relying on them in their traditional form can be misleading, especially when comparing companies in different parts of the world. The question driving this research is whether a company's success is built on a solid foundation of efficient operations and pricing power, or if it is merely a temporary illusion created by borrowing too much money or moving assets quickly in a specific type of economy.
Researchers Rexon Nainggolan, Adat Muli Peranginangin, and Tanggor Sihombing set out to answer this question by examining the financial records of more than 7,000 companies across four major Southeast Asian markets: Indonesia, Malaysia, Thailand, and Singapore. They focused on the turbulent years between 2021 and 2025, a period marked by rapid economic shifts and rising interest rates. By separating the companies into those operating in mature, service-based economies like Singapore and those in emerging, manufacturing-heavy economies like Indonesia, Malaysia, and Thailand, the team could see how different economic environments change what drives a company's success. Their goal was to determine which of the three components of profitability—profit margins, asset efficiency, or debt usage—actually predicts long-term stability and which ones might lead to trouble.
The study uncovered a clear hierarchy in what drives sustainable returns. The researchers found that a company's ability to maintain a healthy profit margin is the most reliable indicator of long-term success across the entire region. This means that companies which can control their costs and charge fair prices for their goods or services are the ones that survive and thrive, regardless of whether they are in a developed or emerging market. This finding supports what the authors call the "Margin Quality Hypothesis," suggesting that real value comes from operational strength rather than financial tricks. In contrast, the study found that relying heavily on debt to boost returns is a dangerous strategy, particularly for non-financial companies. While borrowing money can make a company look more profitable in the short term, the data shows that this approach often leads to a sharp decline in performance when interest rates rise. The researchers observed a "leverage paradox" where the very tool used to accelerate growth becomes the cause of a rapid collapse when the economic climate turns difficult, as the cost of servicing that debt eats away at the company's earnings.
Perhaps the most striking discovery was how the importance of asset efficiency changes depending on where the company is located. In the emerging markets of Indonesia, Malaysia, and Thailand, the speed at which a company turns its assets into sales is a critical driver of success. In these manufacturing and commodity-focused economies, the ability to move inventory quickly and utilize physical capital efficiently is essential for generating returns. However, in the mature, service-oriented market of Singapore, this factor loses its predictive power. There, the speed of asset turnover does not significantly influence long-term returns because the market values high-margin, specialized services more than the sheer volume of asset movement. This reveals that there is no single formula for success; what works in a developing industrial economy is different from what works in a developed service economy.
The implications of these findings are significant for both business leaders and policymakers. The research suggests that companies in emerging markets should focus on improving their operational speed and efficiency rather than simply expanding their balance sheets with more debt. For regulators, the study indicates that rules governing corporate finance should be tailored to the specific economic context of each country, rather than applying a one-size-fits-all approach. The authors argue that in a world of rising interest rates and economic uncertainty, the safest path forward is to prioritize margin-defensive growth and operational efficiency. By understanding that profit margins are the true anchor of stability and that debt can be a fragile foundation, companies can better navigate the complex economic landscape of Southeast Asia and build a more resilient future.
