How to read sector rotation

Sector leadership tells you where money is rotating, which matters more than a single index print. Broad breadth with two or three sectors leading is a healthy trend; a rising index with negative breadth is usually narrow, index-heavyweight driven and fragile. Stocks closing in the top quarter of their day range show buyers in control into the close, and heavy volume confirms the move.

Key takeaways

• Leading sector: Infra (+3.05%) — higher at the time of writing
• Lagging sector: IT (-1.35%) — lower at the time of writing
• Breadth: 27 up / 23 down

About this report

Every figure on this page is read from a primary source at the timestamp shown — exchange boards for equities and indices, the exchange bid book for IPOs, published association rates for bullion, and consolidated exchange quotes for crypto — with no estimation or third-party commentary. Historical fields such as trailing returns and 52-week extremes are computed on the adjusted daily series so splits and bonuses do not create false gaps. A timestamp outside market hours reflects the last traded or last published value, not a live tick.
