The Share Centre said potential replacements include the Scottish Mortgage Investment Trust, whose focus on international investments means it is making the most of a stronger pound, and asset manager Investec.
It added that Rentokil, the pest control group which yesterday posted a jump in revenues, could also be up for promotion, as could plastic packaging company DS Smith.
Helal Miah, investment analyst at The Share Centre, said Dixons Carphone was in a prime position to be relegated.
"The share price has dropped off of late as a result of increasing competition within the sector, particularly from the likes of Amazon.
"Moreover, higher import costs which have been a result of the weaker pound, have hurt the group and in its latest update, Dixons informed the market that it was ‘preparing for all eventualities’ as a result of the increasing uncertain times ahead."
Meanwhile, Intu was at risk after it posted a 67 per cent fall in profits for the year to the end of December - although shares jumped 4.4 per cent yesterday, closing at 293.7p.
Meanwhile, shares in Dixons were up 0.5 per cent today, at 300.5p.
