Zoopla finished Friday as the day’s biggest FTSE 250 faller.

Its shares, which had previously done well last week, slid 5.61% or 10.7 points to 180p after analyst Peel Hunt said that OnTheMarket, launched a week ago, was “proving a viable alternative to Zoopla in terms of inventory”.

Peel Hunt also put a sell rating on Rightmove, an opinion shared by Panmure Gordon and Investec.

Other brokers, however, differ.

For example, Liberum Capital continues to rate Rightmove as a “buy” and Exane BNP Paribas reiterates its “outperform” rating of Rightmove.

So far this month, Panmure Gordon has put a “sell” rating on Zoopla, while Jefferies has downgraded the shares from “buy” to “hold” and Exane from “neutral” to “underperform”.
