Index Funds and Diversification: A Closer Look at Market Dominance
Understanding Index Fund Diversification
Index funds are intended to provide diversification by holding a variety of underlying stocks across different sectors. However, in markets like India and the US, certain sectors dominate the indices.
The Weightage Dynamics of Indian and US Indices
In India, the Nifty 50 Index shows that banking and financial services constitute 34% of the total weightage. In contrast, the IT sector in the S&P 500 holds a staggering 35% weightage. The influence of the top-performing stocks becomes evident when analyzing these figures.
- The top 20% of companies in India's Nifty 50 contribute to 56% of the index weightage.
- In the US, this number escalates to 72% for the S&P 500 index.
This situation reflects the classic Pareto principle, indicating that a small number of stocks can significantly influence overall performance.
Implications for Investors
For passive investors, the choice of index funds may give an illusion of diversification. The dominance of particular sectors, like Financial Services and IT in India and the US respectively, raises the question of whether these investments truly spread risk.
Investors seeking genuine diversification might consider alternatives such as Equal Weighted Indices or Equal Risk Indices.
