What is a point worth in the stock exchange?

In the stock exchange, a "point" typically refers to a one-unit change in the price of a stock or index. For example, if a stock moves from $50 to $51, it has increased by one point. The monetary value of a point can vary based on the number of shares owned; for instance, if you own 100 shares, a one-point increase would translate to a $100 gain. Points are also used to measure changes in indices, where a movement of one point reflects a change in the overall value of the index.
