Ftse 100 Share Price Faces New Volatility as Rightmove Set to Exit Index
Index-tracking funds will be forced to sell Rightmove and easyJet shares and buy IG Group and Tritax Big Box REIT, immediately altering trading flows and the ftse 100 share price for those names. Wednesday at 9: 12 a. m. ET, indicative index data showed Rightmove and easyJet are set to fall out of the FTSE 100, prompting the rebalancing.
Ftse 100 Share Price pressure as funds must trade Rightmove and easyJet
When the changes take place, funds that match the FTSE 100 should sell their Rightmove and easyJet holdings and purchase IG Group and Tritax Big Box REIT, and they should do this whatever the prices are. That mandate creates immediate selling pressure: Rightmove’s shares have plunged roughly 45–50% in recent months, and the forced transactions mean index-driven flows will likely move within hours of the reshuffle.
Rightmove’s record profits collide with a £60m AI plan and slowing near-term growth
Rightmove generated record revenue of £425. 1m and operating profits of £287. 9m, while earnings per share reached a record 28. 1p and the group’s P/E ratio sat at 15. 9. Still, management announced a planned £60m investment in new AI tools and features that is expected to slow earnings growth to low-single digits in the short term, even as forecasts show growth returning to double digits by 2030 and beyond if the strategy succeeds.
IG Group and Tritax Big Box REIT poised for inflows as index seats open
Indicative data suggests IG Group and Tritax Big Box REIT will replace Rightmove and easyJet in the FTSE 100. Passive vehicles that track the index should buy the incoming names to match weightings, potentially sending fresh demand to IG Group and Tritax Big Box REIT on rebalance. For Rightmove, that dynamic could deepen the current sell-off and further depress the ftse 100 share price for the stock at the time of transition.
That said, Rightmove’s recent strength in core operations complicates the picture. The platform saw user engagement and advertiser spending climb, producing the record results above even as home-buying activity softened. Management has also used share buybacks, which helped lift earnings per share by 15% to the record 28. 1p level noted earlier.
Yet the AI spending plan has already spooked investors because it will lower margins near term. The strategy is explicit in aiming for long-term gains, but it also triggered sharp selling: leadership’s November announcement of the £60m investment preceded the steep decline in the stock. There is also a legal risk on the horizon; the company faces a class-action lawsuit alleging abuse of market position, a claim that could complicate management’s pricing strategy.
Passive reweighting and active investor reactions create two conflicting forces for Rightmove. If index funds sell as required, downward pressure will be immediate and measurable. For investors hunting value, the stock’s low valuation and record profits mean some view further weakness as a buying opportunity, while others remain cautious about the short-term margin impact of the AI push and the unresolved legal action.
The next confirmed market event is the FTSE index reshuffle that will formalize which names join and leave the FTSE 100; the changes are expected in the next few days (unconfirmed as of 9: 12 a. m. ET). If the composition change holds, passive funds will execute mandated trades and pressure Rightmove’s share price within hours of the rebalance.
