Which parameters are most useful for sector analysis?
Use three simple lenses to judge sectors: Return % (how much it moved), Market Cap (how big it is), and Volatility (how steady it is).
On the market-level Sector heatmap, you can switch the Return % period and see block size by sector weight.
To assess Volatility, cross-check the same sector in the Bubble chart.
The three key parameters
1) Return % (most important)
- What it tells you: Price change over the period you choose.
- How to use: Check more than one period. For example, today (1D) and the trend (1M/3M).
- Rule of thumb: If a sector is green on 1M and 3M (not just 1D), the strength is more reliable.
2) Market Cap (size/weight)
- What it tells you: How big the sector is in the market.
- How to use: Big green sectors matter more to the overall market than small ones. Treat small sectors as supporting info, not the main signal.
3) Volatility (steadiness)
- What it tells you: Whether gains/losses are smooth or jumpy.
- Where to check: Use the Bubble chart for the same sector (select it via Sectoral indices) and review the spread of stocks.
- Rule of thumb: Prefer sectors that rise across several periods and look reasonably steady.
How to check these in FYERS
- Sector heatmap (market-level): Tap/click time chips (1D/1W/1M/3M/6M/1Y…) to change Return %. Block size shows Market Cap/weight.
- Sector view (inside one sector): Click a sector block to see industries and stocks for a closer look.
- Bubble chart: Pick the same sector under Sectoral indices to judge Volatility (steadiness) alongside other metrics.
Notes
- On the market-level Sector heatmap, block size is fixed by sector weight; colour comes from the selected Return % period.
- Use the same sector in Heatmap and Bubble chart so you compare the same set of stocks.
- Check at least two periods (e.g., 1M and 3M) before making changes.
What if...
| Scenario | Action |
|---|
| Sector is green on 1D but not on 1M/3M | It may be a one-day jump. Wait for 1M/3M to improve before you act. |
| Small sectors are green; big ones are red | Market impact is limited. Focus on what large sectors are doing. |
| Sector is up but feels jumpy | Open the Bubble chart for that sector to check steadiness; consider smaller changes. |
| Two sectors look similar on Return % | Pick the larger sector (bigger block) or the one that looks steadier in Bubble chart. |
