CNX 500 vs Nifty 50 : Data Worth Noticing

CNX 500 vs Nifty 50: How Market Weight and Performance Really Work

The Weight of the Titans: Understanding the CNX 500's Composition ⚖️

The CNX 500 index, despite its name, is heavily influenced by a select few. Our analysis reveals that heavyweights like HDFC Bank (7.7%), ICICI Bank (5.3%), and Reliance (nearly 5%) dominate its composition. In fact, the top 10 stocks collectively command a significant 32% of the index's weight.

This concentration means that the performance of these few titans largely dictates the overall movement of the CNX 500.

Nifty 50's Influence: A Half-Share in the CNX 500 📊

Delving deeper, we find an even more striking imbalance: the Nifty 50 stocks (which are 50 of the 500) account for a whopping 50% of the CNX 500's total allocation. This stark reality highlights how disproportionately the top 50 companies influence an index designed to represent 500. Conversely, the remaining 450 stocks, which represent a vast majority, share the other 50% of the weight.

This structure implies that even strong performance from these smaller companies may barely register in the overall index movement.

The Evolving Landscape: Nifty to CNX 500 Ratio 📉

Despite the inherent skew towards the top 50, a fascinating trend emerges when we examine the Nifty to CNX 500 ratio chart. 

This ratio has been on a consistent downward trajectory for several years. What does this suggest? It points to a compelling narrative: the lower-tier stocks within the CNX 500 (the "other 450") have been outperforming the Nifty stocks during this period.

• Dropping Ratio: Indicates stronger performance from a broader base of stocks within the CNX 500 beyond just the Nifty 50.

• Rising Ratio (Future Indicator): If this trend reverses and the ratio begins to climb, it would signal that Nifty stocks are finally regaining their outperformance against the rest of the CNX 500.

For now, the data suggests that the "rest of the CNX 500" have truly overshadowed the Nifty stocks.

Key Takeaways:

• Concentration Risk: The CNX 500's heavy reliance on a few large-cap stocks means its performance is highly sensitive to their movements.

• Beyond the Top 50: The consistent decline in the Nifty to CNX 500 ratio indicates a period where a broader range of companies within the CNX 500 (outside the Nifty 50) have delivered stronger returns.

• Market Breadth Matters: Investors looking beyond just the Nifty 50 might find significant opportunities in the wider CNX 500 universe, particularly in the mid and small-cap segments that have shown relative outperformance.

• Indicator for Future Trends: Monitoring the Nifty to CNX 500 ratio can provide valuable insights into whether market leadership is shifting back towards large-cap Nifty stocks or if the broader market continues to drive returns.

What To Read This Week ?

Today’s Market Update

The day began with some interesting political drama. President Trump tweeted that India–US relations are improving and that both sides may soon find a negotiating point. But just an hour later, he urged the European Union to put a 100% tariff on India.

His mood changes quickly, and until some actual decisions are made, nothing can be taken seriously. Thankfully, the market did not pay much attention to these tweets and continued to move up.

• Nifty opened with a gap up and closed the day with a gain of 0.42%.

• Nifty Next 50 also rose 0.43%, while mid-caps gained 0.95%, erasing the losses from three days ago. Small caps ended with a 0.66% gain, and the banking index was up 0.59%.

• Gold continued its relentless rally, gaining 0.71% to trade around ₹10,971 per 10 grams, now approaching the ₹11,000 mark. This rise has been very unusual, as such rallies usually pause for a few days in between. Jewelers are even charging a premium of ₹2,500–3,000 per 10 grams, which is surprising after such a big run-up.

Other Market Triggers

• Bharat Electronics and Tata Consumers performed well, along with some banking and finance names.

• In the Nifty Next 50 space, Dmart, Swiggy, and TVS Motors faced profit-taking, while Hindustan Aeronautics, CG Power, JSW Energy, and Adani Group stocks moved up.

• Avanti Feeds jumped 15% after the EU approved 102 new Indian fishery units for export.

• Oracle Finance gained 10% as its US parent rallied on optimistic guidance.

What to watch next ?

• The session closed with optimism across most sectors and some caution around auto and consumption.

• The market has confidence that something positive will eventually come out of the talks. The belief is that there is very little chance of real damage, and with this hope, the market is moving forward.
