Key Takeaways
- Investors prioritize stock quality over index selection
- Morgan Stanley research reveals index choice accounts 10% of returns
- Fundamentals drive 90% of investment outcomes
- Companies' financials outweigh index performance
Indian equities have long been dominated by the BSE Sensex, a benchmark index comprising 30 of the country’s largest and most liquid stocks. But what if I told you that the stock index you invest in isn’t always the most important decision? In fact, according to Morgan Stanley research, the stock index you choose can account for as little as 10% of your overall investment returns, while the quality of the stocks within that index can make up the remaining 90%. This is a stark reminder that, in the world of investing, it’s not just about the index, but about the underlying fundamentals of the companies that make up that index.
Take the case of Tata Motors, for example. While the company’s stock was part of the BSE Sensex, its struggles with debt and declining sales weighed heavily on the overall performance of the index. On the other hand, companies like Infosys, with its strong track record of earnings growth and dividend payments, have consistently outperformed the broader market. So, what’s driving this disparity, and what can investors do to maximise their returns?
Setting the Stage
The Indian stock market has been on a tear in recent months, with the BSE Sensex hitting an all-time high of 62,453 points in March. But beneath the surface, there are signs of growing inequality and inefficiency in the market. While the top performers in the Sensex have seen their valuations soar, many smaller companies and mid-cap stocks have struggled to keep pace. This is a concern for regulators, who are worried that the market is becoming increasingly concentrated, with a handful of large-cap stocks dominating the landscape. As one analyst at Goldman Sachs noted: “The Indian market is becoming a two-tier system, where the top performers are getting richer and the rest are getting left behind.”
One reason for this disparity is the way that investors are allocating their assets. According to a recent survey by Citi, institutional investors are increasingly focusing on large-cap stocks, which are perceived as safer and more liquid. But this shift has left smaller companies and mid-cap stocks in the cold, with many struggling to attract the attention and capital they need to grow. As a result, the market is becoming increasingly skewed towards the large-cap stocks, which are dominating the indices and driving the overall performance of the market.
What's Driving This
So, what’s driving this trend? One reason is the changing nature of Indian capital markets. With the rise of exchange-traded funds (ETFs) and index funds, investors are increasingly looking for easy and efficient ways to invest in the market. As a result, they are opting for large-cap stocks, which are perceived as safer and more liquid, over smaller companies and mid-cap stocks. But this shift has also created a self-reinforcing cycle, where the large-cap stocks are dominating the indices and driving the overall performance of the market.
Another reason is the rise of passive investing. With the growth of ETFs and index funds, investors are increasingly turning to passive investment strategies, which involve tracking a particular index or benchmark. But this approach can create a problem, where investors are not incentivised to do their own research and analysis, but rather simply follow the crowd and invest in the same stocks that are dominating the indices. As one analyst at Bank of America Merrill Lynch noted: “Passive investing has created a problem, where investors are not thinking about the underlying fundamentals of the companies they are investing in, but rather simply following the crowd and investing in the same stocks.”
Winners and Losers
So, who are the winners and losers in this new landscape? The winners are the large-cap stocks, which are dominating the indices and driving the overall performance of the market. Companies like Tata Consultancy Services (TCS), Infosys, and Reliance Industries have seen their valuations soar, with investors clamouring to get a slice of the action. But the losers are the smaller companies and mid-cap stocks, which are struggling to keep pace with the market. Companies like Hindustan Unilever, Maruti Suzuki, and Bajaj Auto have all seen their valuations stagnate, as investors increasingly focus on the large-cap stocks.

Behind the Headlines
Behind the headlines, there are signs of growing concern among regulators and investors about the growing inequality and inefficiency in the market. The Securities and Exchange Board of India (SEBI) has been monitoring the situation closely, and has taken steps to address the growing concentration in the market. As SEBI Chairman Ajay Tyagi noted: “We are concerned about the growing concentration in the market, and are taking steps to address the issue.” But critics argue that more needs to be done, with some calling for a more comprehensive overhaul of the market structure.
Industry Reaction
Industry reaction to the trend has been mixed. Some investors have welcomed the shift towards large-cap stocks, seeing it as a safer and more efficient way to invest in the market. As one portfolio manager at Franklin Templeton noted: “We are seeing a shift towards large-cap stocks, which are perceived as safer and more liquid. This is a positive trend for investors, who are looking for stable returns in a volatile market.” But others have expressed concern about the growing concentration in the market, and the potential risks that come with it. As one analyst at Jefferies noted: “The Indian market is becoming a two-tier system, where the top performers are getting richer and the rest are getting left behind. This is a concern for regulators, who need to take steps to address the issue.”

Investor Takeaways
So, what can investors do to maximise their returns in this new landscape? The answer is to focus on the underlying fundamentals of the companies they are investing in, rather than simply following the crowd and investing in the same stocks that are dominating the indices. This means doing your own research and analysis, and being willing to take on more risk in search of higher returns. As one analyst at Credit Suisse noted: “Investors need to be more selective and take a more active approach to investing in the Indian market. This means looking beyond the large-cap stocks and focusing on smaller companies and mid-cap stocks that have strong growth potential.”
Potential Risks
But there are also potential risks to consider. One risk is that the growing concentration in the market could lead to a decline in liquidity, as investors become increasingly focused on the large-cap stocks. This could have a knock-on effect on the broader market, where smaller companies and mid-cap stocks struggle to attract the attention and capital they need to grow. Another risk is that the shift towards large-cap stocks could lead to a decline in innovation, as investors become increasingly focused on established players and less willing to take on the risk of investing in smaller companies and start-ups.

Looking Ahead
Looking ahead, the trend is likely to continue, with investors increasingly focusing on large-cap stocks and smaller companies and mid-cap stocks struggling to keep pace. But regulators and investors are starting to take steps to address the growing inequality and inefficiency in the market. As one analyst at UBS noted: “We are seeing a shift towards large-cap stocks, but this is not necessarily a bad thing. In fact, it could be a positive trend for investors, who are looking for stable returns in a volatile market.” But others are more cautious, with some warning that the trend could lead to a decline in liquidity and a decline in innovation.
Ultimately, the stock index you invest in is just one part of the equation. What matters even more is the quality of the stocks within that index, and the underlying fundamentals of the companies that make up that index. By focusing on the fundamentals and being willing to take on more risk in search of higher returns, investors can maximise their returns and achieve their investment goals. But for now, the trend is clear: the stock index you invest in is not always the most important decision.
