Overview of FTSE 100

Definition and Composition

The FTSE 100 Index consists of the top 100 companies by market capitalization on the LSE. Market capitalization is calculated as:

\text{Market Capitalization} = \text{Share Price} \times \text{Number of Outstanding Shares}

Historical Context

The FTSE 100 was introduced on January 3, 1984, by the Financial Times and the London Stock Exchange as a means of benchmarking the UK’s largest companies.

Purpose and Importance

The FTSE 100 serves multiple purposes in the financial markets:

Benchmark Index: Investors and fund managers use it to track the performance of the UK market.
Economic Indicator: It provides insight into the health of the UK economy, particularly the corporate sector.
Investment Tool: Various financial products, such as Exchange-Traded Funds (ETFs) and mutual funds, are based on the FTSE 100.

Key Features

Market Capitalization-Weighted

The weighting of each component in the FTSE 100 is proportional to its market capitalization. This means larger companies have a greater impact on the index’s movements.

Blue-chip Stocks

The index includes blue-chip stocks, which are large, financially sound, and well-established companies known for their reliability and performance.

Regular Rebalancing

The FTSE 100 undergoes quarterly reviews wherein companies may be added or removed based on their market capitalizations to ensure it accurately represents the top 100 companies.

Comparison with Other Indices

FTSE 250

While the FTSE 100 comprises the largest 100 companies, the FTSE 250 includes the next largest 250, offering a broader representation of mid-cap firms on the LSE.

S&P 500

Compared to the S&P 500 in the US, which tracks 500 large-cap US companies, the FTSE 100 provides a narrower view, focusing exclusively on top UK firms.

FTSE Group: The FTSE Group, now part of FTSE Russell, is responsible for creating and maintaining a range of indexes, including the FTSE 100.
Market Capitalization: The total market value of a company’s outstanding shares. It is a key factor in determining the composition of the FTSE 100.
