The sector rotation endpoint shows you which parts of the NGX market are gaining traction and which are pulling back.For every sector it calculates the average price change across all constituent companies over three windows (one day, seven days, and 52 weeks) along with aggregate market capitalisation, value traded, total share volume, and a breadth count of advancers, decliners, and unchanged stocks.Use this data to identify rotational flows between sectors or to build sector-performance heat maps.
