Summary
India’s equity market continues to grow, prompting discussions among market participants about the relevance of existing stock classification frameworks. The current system that categorizes companies based solely on their rank has drawn criticism for its rigidity, potentially misrepresenting the broad diversity and growth of India’s listed landscape. Experts are calling for a re-evaluation of these classifications to better reflect changing market dynamics.
Outdated Classification Framework
The Indian stock market has seen exponential growth in market capitalisation over the years. However, the classification of large-cap stocks is still confined to just the top 100 companies. A senior market expert, speaking anonymously, emphasized that the criteria for classification should shift from a mere count of stocks to market capitalisation thresholds. This perspective suggests that as the market grows, the definitions of what constitutes large, mid, and small-cap stocks should also evolve to provide a more accurate representation of the market landscape.
Many agree that the current classification fails to account for companies that, despite having significant market capitalisation, fall outside the established categories. For instance, companies valued at around ₹40,000 crore classified as small-caps may be more deserving of attention and funding, given their substantial size.
The Mid-Cap Churn Problem
Concerns about the high turnover rate among mid-cap stocks have emerged as a significant issue. Data from Kotak Institutional Equities reveals that only 46 of the stocks in the Nifty Midcap 150 Index five years ago remain in the index today. Over the last five years, 275 unique stocks have entered or exited the index, indicating a lack of stability in what is often relied upon as a benchmark for investment decisions.
Sanjeev Prasad, Co-Head and Managing Director at Kotak Institutional Equities, pointed out that such rapid changes make historical comparisons unreliable. He noted that the constant reshuffling is typically influenced by market narratives rather than underlying fundamentals, contributing to a “survivorship bias” where only successful stocks are considered, leaving crucial data from many companies out of the equation.
Hypothetical scenarios indicate that maintaining a consistent portfolio would have resulted in significant returns—68%—over five years, compared to the 116% generated by the reconstituted index. This raises questions about the efficacy of active management and the benchmarks being used.
The Case for New Categories
Market veteran Arun Kejriwal advocates for the introduction of new classifications, specifically “micro-cap” and “mini micro-cap” categories. He argues that the existing three-tier framework oversimplifies the structure of India’s equity market and does not account for the growing number of smaller IPOs that have recently emerged.
Kejriwal emphasizes that current classifications can misrepresent the dynamics of the market. By introducing five or six distinct categories, investors and mutual funds would have more flexibility in allocating funds, allowing a better reflection of the market’s breadth. Furthermore, he suggests revisiting the upper limit of large-cap classifications as India’s economy continues to mature.
What This Means
The debate over stock classification has serious implications for the investment landscape in India. As mutual funds manage larger pools of capital and retail investor participation increases, a rigid classification structure may restrict the flow of money primarily to a narrow set of stocks. This could sideline a broader segment of listed companies that have significant potential. Businesses and institutional investors alike may face challenges in making informed decisions based on outdated frameworks.
As the Indian equity market matures, there is growing pressure for classification systems that better mirror the complexity and diversity of listed companies. Such changes could enhance investment strategies, improve capital allocation, and ultimately support a more robust and inclusive market environment.
