Sectors often move very differently from each other. On any given day, Banking may be strong while Metals might be under pressure. Over a month, the story may reverse completely.
If you only look at the Nifty 50 index, you miss these internal shifts.
That is why we built Sector Heatmaps.
Instead of checking indices individually, you get a single visual snapshot of how the entire market is behaving. You can see where momentum is building and where it is fading across different timeframes.
1. The Block View (Your default map)
This is the first thing you see when you open the tool. It tells you who is leading.
Block Size: Represents the Sector Market Cap. Bigger blocks (like Finance) have a higher weight in the market.
Block Colour: Represents Performance. Green is up. Red is down.
Just scan the map. If you see big green blocks, the market is being driven by heavyweights. If you see deep red blocks, those sectors are dragging the market down.
2. Drill down instantly
A sector might be green, but is it the whole sector or just one stock pulling it up?
Click on any sector block. The heatmap opens up to show you all the stocks inside that sector.
This layout works exactly like the main Heatmap tool we discussed in our previous blog. You can instantly see which specific stocks are driving the sector's move.

3. Timeframes tell the story
Sector behaviour changes depending on the timeframe. A sector might be down today but is actually the strongest performer over the last year.
Use the filters at the top to change your perspective:
1D, 1W, 1M: Use these to spot short-term momentum and quick reversals.
3M, 6M, 1Y: Use these to understand medium-term trends.
3Y, 5Y: Use these to see long-term structural strength.
4. Switch to Bubble View (Volatility)
If you want to understand risk alongside return, switch to the Bubble Chart view.
This adds a new dimension to your analysis:
Bubble Size: Market Cap.
Bubble Colour: Return %.
Position: This helps you spot the sectors based on volatility (Beta) and returns.
This helps you identify the nature of the sector:
High Return, Low Volatility: The ideal steady performers.
High Beta: Sectors that swing wildly in comparison to the market.
Outliers: Sectors that are moving independently of the general market trend.
Just like the Block view, clicking a bubble opens the detailed stock view for that sector.

5. NSE vs BSE
By default, we show NSE sectoral indices. However, if you prefer the BSE classification or want to see a broader list of sectors, simply toggle the switch to BSE. Everything updates automatically.
A Practical Example: Finding a Turnaround
Let’s say you are looking for a sector that has been beaten down but is starting to gain upward momentum.
Select 1 Year timeframe. Look for Red blocks.
Switch to 1 Month. Did any of those Red blocks turn Green?
Switch to 1 Week. Is it staying Green?
If yes, you have found a sector that is rotating. Click on that block to open the stock list and see which specific names are leading the recovery.
What usually takes 15 minutes of scanning charts is now visible in seconds.
Go to Markets > Analytics > Sector Heatmap on FYERS Web or App. Start with the Block View to see the mood, check the Timeframes to see the trend, and Drill Down to find the trade.
