The FTSE 100 has been in existence since 1984, when it started trading at 1,000 points. Since then, it has experienced a number of booms and busts, with it currently trading at over 7,000 points at the time of writing.
The FTSE 100 contains some of the largest companies in the world. As such, it has an international bias versus the FTSE 250 and FTSE All-Share.
Since it contains the largest listed companies in the UK, its growth rate has historically under-performed the FTSE 250. However, the FTSE 100’s dividend yield has generally been higher than that of the FTSE 250.
