Sensitive Index, popularly known as the Sensex, is a weighted stock market index of the top 30 companies in India that trade on the Bombay Stock Exchange (BSE). The index includes well-established companies that trade on the BSE.
The method of calculation of Sensex is a free-floating market capitalization method. The list of companies included in the sensex could keep on changing. An index committee selects and reviews the 30 companies that comprise the Sensex regularly. This committee comprises academics, mutual fund managers, finance journalists, independent governing board members, and other financial market participants. While doing so, the committee adheres to a set of criteria. The Index reflects the general market tendency and consumer confidence.
