Abrdn PLC (LSE:ABDN), Hikma Pharmaceuticals PLC (LSE:HIK, OTC:HKMPF) and Howden Joinery Group (LSE:HWDN) PLC look likely to drop out of the FTSE 100 next month, to be replaced by F&C Investment Trust PLC, Harbour Energy PLC (LSE:HBR) and ConvaTec Group PLC (LSE:CTEC).
The FTSE quarterly index review will be decided based on today's (Tuesday, 30 August) closing share prices, with the changes made so the indices will contain their new constituents at the start of trading on Monday 19 September.
"Rebalancing" of the indices is based on market capitalisation, with companies outside the largest 110 companies in the index automatically relegated, which looks likely to be the case for the latest three blue-chip demotions.
Index organisers FTSE Russell will confirm the changes after market close on Wednesday, along with rebalancing of London's other indices.
Most of the changes are as predicted in the indicative changes it supplied last week.
It appears that five companies will drop out of the FTSE 250 into the small cap ranks: XP Power Ltd (LSE:XPP), Provident Financial PLC, Chrysalis Investment Ltd, Tyman (LSE:TYMN) PLC and Greencore Group PLC.
Based on the closing market caps, they will be replaced in the mid-cap index by Bluefield Solar Income Fund Ltd, NextEnergy Solar Fund Ltd (LSE:NESF), Puretech Health PLC, Go-Ahead Group (The) PLC and either Warehouse REIT PLC (AIM:WHR) or TwentyFour Income Fund Ltd.
