What are the requirements for inclusion in the FTSE 100?

First, a company’s shares must be listed on the LSE and be denominated in pounds sterling.

The company must also meet the minimum free float and stock liquidity requirements as established by the FTSE Group that operates and maintains the index.

The final and most obvious criterion is that a company must be one of the top 100 companies by market capitalisation on the exchange.

When are changes made to the constituents of the FTSE 100?

A review of the FTSE 100 constituents is undertaken every quarter, usually in March, June, September and December. The rules for promoting or removing a company from the index are as follows:

  • A share is promoted into the FTSE 100 if it rises to 90th position or above (by market cap).
  • A share is removed from the FTSE 100 if it falls to 111th position or below (by market cap).

This system is meant to reduce the number of continuous changes to the index as it ensures that a company only gets relegated or promoted when it clearly needs to be moved.

That being said, just because a company hasn’t dropped to 111th position or below doesn’t mean that it won’t be relegated. It might still need to be dropped to make way for other companies that have met the inclusion criteria and are proving themselves more worthy of a place on the index. 

How can I invest in the FTSE 100?

There are two main ways to invest in the FTSE 100:

  1. Purchase individual shares in a FTSE 100 constituent company
  2. Invest in an exchange-traded fund (ETF) that tracks the index’s prices

Before you can start investing, you will need a share dealing account. To help you narrow down your options, check out our comparison of some of the top providers of share dealing accounts in the UK.

You can also invest in the Footsie through a stocks and shares ISA. Investing this way comes with the added benefit of tax efficiency. When you invest through a stocks and shares ISA, any income or gains from your investment are not taxed.

Keep in mind, however, that tax rules can change and their effects on you will depend on your individual circumstances.
