LONDON, June 10 (Reuters) - Russian companies' exodus fromthe UK's benchmark share index looks set to continue onWednesday, when steelmaker Evraz and miner Polymetal are likelyto be relegated in the latest quarterly review.
Both stocks have lost more than 40 percent in a torrid yearso far for the broader Russian mining group, which includes ENRC, beset by slowing demand, corruption probes andregulatory inquiries that have hit investorsentiment.
Evraz, Russia's biggest steel producer which isalso included in the mining sub-index, and Polymetal were the 149th and 118th biggest companiesrespectively on the London stock exchange by marketcapitalisation as of June 7. They are likely to follow copperminer Kazakhmys, demoted to the FTSE 250 inMarch, when the reshuffle is announced on Wednesday.
If ENRC, the subject of a potential buyout, iseventually taken into private ownership that would leave noRussian mining stocks in London's blue-chip index.
Any company falling to 111th position or below isautomatically deleted from the FTSE 100. Any company rising to90th position or above is automatically added to the FTSE 100,according to FTSE rules.
Traded volumes and volatility in the stocks likely to movecan jump in the days around the reshuffle as pension funds,exchange-traded funds and investment trusts with FTSE 100tracker products re-weight their portfolios.
In terms of their market cap based on June 7 prices,Britain's biggest supplier of building materials, Travis Perkins, and housebuilder Persimmon, the 90th and 92ndlargest listed UK companies, respectively, are the most likelyreplacements for the Russian miners.
Also in contention for promotion to the FTSE 100 are privateequity group 3i and shopping centre owner IntuProperties, looking for a swift return to the UK's bluechip index after being demoted in March's rejig, car insurerDirect Line and systems testing firm Invensys.
Candidates for demotion to the FTSE 250 also includeoil services firms AMEC in 111th place and John Wood in 110th place plus outsourcer Serco in 112thplace, according to data from Starmine.
Another Russian miner, Petropavlovsk, also facespossible demotion, to the FTSE Small Cap index from theFTSE 250 along with asset manager Dexion Absolute Sterling, customer management solutions provider SDL andexplorer New World Resources.
