How to Read the Sector Heatmap

The heatmap above shows every NSE sectoral index as a coloured tile. Each tile's size represents that sector's market capitalisation (Nifty Bank is largest because it weighs most), and each tile's colour shows today's percentage change: deep green for strong gainers, light green for mild gainers, light red for mild losers, and deep red for sharp losers.

Hover or tap any sector to see the exact percentage change. Use this view to instantly answer the question: which sector is leading or lagging the broader market right now?

Tip: Don't just look at colour. A small tile with a large percentage move (e.g., a +3% Nifty Realty) is often a stronger trade signal than a large tile with a small move (e.g., a +0.5% Nifty Bank).

Today's Top Performing Sectors on NSE

The sector heatmap above shows real-time performance for all 13 NSE sectoral indices. To find today's top performing sector, look for the largest deep-green tile — that's the index with the strongest percentage gain so far. The smallest red tile, conversely, is today's weakest sector.

Sectoral leadership shifts intraday. A sector that's leading at the open may not lead at close. Refresh this page through the session to see how leadership rotates between Bank Nifty, IT, Auto, FMCG, Pharma, Metal, and the broader market sectors.

Compare Any Two NSE Sectors Today

The sector detail table below the heatmap lets you compare sectors head-to-head. Use it for three common trading workflows:

Pair trading: Find a strong sector and a weak sector on the same day. Long the strong, short the weak (using sector ETFs or futures where available).
Sector rotation: If a defensive sector (FMCG, Pharma) is leading while cyclicals (Auto, Metal, PSU Bank) lag, that's often a risk-off signal. The reverse signals risk-on.
Confirmation trades: If you're bullish on Bank Nifty, check whether Nifty Pvt Bank and Nifty PSU Bank are also green. If they diverge, the move may be narrow and unsustainable.

Understanding Sector-Wise Advance/Decline (Market Breadth)

Each row in the sector detail table shows an Advance/Decline ratio bar — a small green and red bar indicating how many constituent stocks in that sector are up versus down today. This is more honest than the index percentage move alone.

Example: Nifty Bank may be up +2.6% with all 12 stocks green. That's strong breadth and suggests genuine sectoral momentum. Compare this to a sector where the index is up +1% but only 4 of 10 stocks are green — that's a narrow rally driven by a few heavyweights, and far less reliable.

Look for sectors with both a strong percentage move and wide breadth. That's where sustainable trends form.

Frequently Asked Questions

Which sector is performing best on NSE today?

The sector heatmap at the top of this page shows the current best-performing NSE sector in real time. Look for the largest deep-green tile — that's today's leader. The sector detail table below ranks all 13 sectoral indices by percentage change so you can see the full ranking. Data refreshes every minute during market hours.

What is a sector heatmap and how do I read it?

A sector heatmap is a visual snapshot of stock market sectors each sector is shown as a coloured tile. Tile size represents market capitalisation (bigger sectors = larger tiles) and colour represents today's percentage change (green = up, red = down, intensity shows magnitude). It's the fastest way to see which parts of the market are leading or lagging without reading 13 separate index pages.

How is sector-wise performance calculated?

Each sectoral index (e.g., Nifty Bank, Nifty IT) is calculated by NSE as a free-float market-cap weighted average of its constituent stocks. The percentage change shown is today's change versus the previous day's close. Constituent counts vary by sector — Nifty Bank has 12 stocks, Nifty IT has 10, Nifty Pharma has 20, and so on.

What's the difference between Nifty Bank and Nifty Pvt Bank?

Nifty Bank tracks the 12 most liquid Indian banking stocks, both public and private sector. Nifty Pvt Bank is a narrower index tracking only private sector banks (HDFC Bank, ICICI Bank, Axis, Kotak, IndusInd, etc.). Nifty PSU Bank tracks only public sector banks (SBI, Bank of Baroda, PNB, Canara, etc.). On any given day, these three indices can move in different directions depending on what's driving the news cycle.

How often is the sector data on this page updated?

The heatmap and sector detail table update every minute during NSE trading hours (9:15 AM – 3:30 PM IST, Monday to Friday). Outside market hours, the page shows the most recent close. You can toggle auto-refresh on or off using the control at the top of the page.
