Persimmon is likely to drop out of the FTSE 100 next week for the first time in a decade.
FTSE Russell, the index provider, will reveal its latest quarterly reshuffle on Wednesday 30 August. Based on data drawn from the market close on Friday, Persimmon, as well as Abrdn, are expected to be demoted to the FTSE 250.
The housebuilder joined the top tier of the London Stock Exchange in 2013, the same year that the then chancellor George Osborne set up Help to Buy.
