Monthly development FTSE All-Share Index 2015-2024
The FTSE All-Share Index shed around one quarter of its value between December 2019 and March 2020, largely due to coronavirus (COVID-19) pandemic, but likely also influenced by the uncertainty around Brexit at the time. Since then it has partially recovered to exceed 4173 points at the end of January 2024.
The FTSE All-Share Index is the aggregation of the FTSE 100, FTSE 250 FTSE Small Cap indexes, and represents around 98-99 percent of the total UK market capitalization. Since December 29, 2017 the index has been comprised of the 641 largest U.K. companies by market capitalization on the London Stock Exchange.
