Sector Buy-Sell and Rotation Guide

العربية

Learn to compare sector direction, relative activity, timeframe, and breadth without confusing flow with a forecast.

A single stock can distract from what is happening across its sector. This page compares classified buying and selling activity by sector so you can choose where to investigate first. Check individual constituents next: a few large companies can dominate the sector summary.

What the page shows

Field or controlHow to use it
SectorGroups related businesses, although individual stocks can move differently.
Buy and sell portionsCompare classified activity and hover to inspect the values.
Percentage barsThe normalized view compares the balance within each sector. Equal-looking bars need not represent equal dollar activity.
PeriodChoose the available day, multi-day, week, or month period, comparing sectors over the same window.
ResetReturns the chart to its default selection; wait for the updated chart before reading it.

Recommended workflow

  1. Choose the horizon relevant to the intended trade.
  2. Compare several sectors rather than reading one value alone.
  3. Check whether leadership is broad across constituents or driven by a few large names.
  4. Open representative symbols and compare price, volume, news, and block-volume context.
  5. Recheck after index rebalancing, macro releases, and session changes.

How to interpret the result

  • Relative leadership is different from an absolute bullish signal.
  • Concentrated activity in a few mega-cap names can distort the group view.
  • Rotation can be fast and mean-reverting on short windows.

Common mistakes

  • Comparing windows of different lengths.
  • Assuming every constituent follows the sector aggregate.
  • Ignoring market-cap concentration and macro catalysts.

Risk and limitations

Sector aggregates simplify diverse companies and can change quickly. Verify the constituents and current market context.

Broad participation or one large contributor?

Compare several stocks from an interesting sector rather than only its largest company. Check whether the activity persists across periods and agrees with price, or comes mainly from one trade or event.

Page components explained

Compare sector activity
