How much is one point of the FTSE 100 worth?

One point of the FTSE 100 index represents a collective change in the market capitalization of the 100 largest companies listed on the London Stock Exchange. Specifically, a one-point change reflects a £1 increase or decrease in the total market value of these companies, divided by a specific divisor used in the index calculation. The actual monetary value of one point can fluctuate based on the total market capitalization of the index and the divisor, but it generally indicates a change in investor sentiment and market performance.
