The UK100 Index, often referred to as the FTSE 100 or simply the Footsie, is a well-known and widely tracked stock market index in the United Kingdom. It represents the performance of the 100 largest companies listed on the London Stock Exchange (LSE) based on market capitalization.
Understanding the UK100 Index

The composition of the index is determined by market capitalization, with larger companies having a more significant impact on the index’s performance.

The UK100 Index is calculated using a market capitalization-weighted methodology.

Number of Shares: The total number of outstanding shares of each constituent.
Free Float Adjustment Factor: Represents the portion of shares that are available for trading in the open market.
