Nifty Indices Risk: Broader Doesn’t Mean Safer, Data Reveals

Contrary to common market assumptions, diversifying across a broader range of companies in the Indian equity market does not inherently lead to lower investment risk. The Nifty 50, Nifty Next 50, and Nifty 500 indices are all officially categorized as ‘Very High’ risk by NSE Indices.

• NSE Indices Risk Classification (February 2026): Very High
• Applicable Indices: Nifty 50, Nifty Next 50, Nifty 500

The Nifty 50, often seen as the benchmark for large-cap performance, exhibits significant sectoral concentration. Financial services firms alone account for a substantial portion of its composition, presenting specific exposure risks to investors.

• Nifty 50 Financial Services Weight (July 31, 2026): 36.18 percent

While the Nifty Next 50 covers the subsequent 50 largest companies and the Nifty 500 extends coverage to 500 firms, this wider reach does not mitigate volatility. The Nifty 500 aims for a broad economic view but introduces different risk dynamics.

Risk Scores Challenge Diversification Myth

An analysis of internal risk scores reveals an intriguing trend: the Nifty 500, despite its extensive coverage, registers a higher risk score compared to its more concentrated counterparts. This data challenges the conventional wisdom that a broader market index automatically reduces portfolio risk for investors.

• Nifty 500 Risk Score: 5.60
• Nifty Next 50 Risk Score: 5.43
• Nifty 50 Risk Score: 5.33

The inclusion of numerous mid-cap and small-cap companies within the Nifty 500 contributes directly to this increased volatility. Investors should therefore evaluate these indices based on their specific long-term investment objectives rather than solely on the number of constituent companies.
