What is Sector Index?
In finance, a sector index refers to a benchmark that tracks the performance of a particular industry or sector within an economy. This index is typically composed of a group of companies operating within the same industry or sector, and is calculated based on their stock price movements over time.
Sector indices are commonly used by investors and analysts to evaluate the performance of mutual funds or other investment vehicles that specialize in a particular sector, and can also provide insights into the overall health and trends of the industry or sector being tracked.
