The FTSE 100 will today welcome two new companies Meggitt PLC (LSE:MGGT) and Wm Morrison Supermarkets PLC (LSE:MRW), although as both are currently takeover targets, they are likely to be replaced before long.
Making way for them was Just Eat Takeaway.com NV (LSE:JET, NASDAQ:GRUB), which can no longer be included in the blue-chip benchmark as it's moved its home registration to the Netherlands, and Weir Group (LSE:WEIR), which has seen its market valuation slip to 111th in the list of the London Stock Exchange's largest companies, which means it is automatically demoted in the quarterly reshuffle by index organiser FTSE Russell.
The current likeliest candidates to replace Meggitt and Morrisons if they are taken over, as looks likely, are Dechra Pharmaceuticals PLC, Howden Joinery Group (LSE:HWDN) PLC, Wizz Air Holdings PLC and Electrocomponents (LSE:ECM) PLC, which are all valued at or above £5bn, putting them in or close to the top 100 largest companies on the London Stock Exchange.
Joining Weir in the FTSE 250, but promoted from the small cap ranks, are Baltic Classifieds Group PLC, Blackrock Throgmorton Trust, Bridgepoint Group PLC (LSE:BPT), Darktrace PLC, Draper Esprit PLC and Endeavour Mining PLC (LSE:EDV, TSX:EDV, OTCQX:EDVMF, FRA:6E2). Endeavour has joined after re-registering its nationality to the UK from Canada.
Dropping out of the mid-cap index are Avon Protection PLC, Civitas Social Housing PLC, Temple Bar Investment Trust PLC, Tullow Oil PLC and Wickes Group PLC.
The changes take effect from the start of trading today.
