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...

ScenarioAction
Sector is green on 1D but not on 1M/3MIt may be a one-day jump. Wait for 1M/3M to improve before you act.
Small sectors are green; big ones are redMarket impact is limited. Focus on what large sectors are doing.
Sector is up but feels jumpyOpen 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.
