The Heng Seng Index is a sort of "average" of the stocks and represented in points form. A point on index is just a mathematical concept, it does not equate to any monetary value. However, if you know the exact calculation of the index, then you could try to estimate the potential movement of the index if some of its constituents change. For example, if HSBC's share price move up by 10%, then it would equate to x points increase on the Heng Seng Index
