Shares in both Rightmove and Zoopla have enjoyed a strong week – Rightmove after Swiss bank UBS raised its price target to 3470p, and Zoopla despite being heavily “shorted”.

UBS tipped Rightmove shares as a buy. It said that the launch of OnTheMarket had had little impact on Rightmove, “with Zoopla suffering the lion’s share of churn”.

The bank’s analysts said: “With all the noise it caused, OTM’s real impact on Rightmove has simply been to dilute the competition.”

UBS added: “The emergence of a credible third player has helped to cement Rightmove’s market-leading position in the longer term.”

UBS’s latest analysis is interesting, given that in January it downgraded Rightmove to “neutral” saying that it was a great business but with “limited upside”.

On Wednesday, Rightmove continued with its share buy-back programme, announcing that it had bought 17,000 shares through UBS. It paid between 3099 .50p and 3142p.

Meanwhile Zoopla has been featured in a “shortlist” in an Investors Chronicle article.

The piece begins: “What do Tesco, Zoopla, Flybe and Glencore have in common? Answer: their shares are all currently shorted by major fund managers.”

It goes on: “Take Zoopla. Investors are currently unsure of the likely damage to the property website from the recent entrance of estate agent-owned competitor OnTheMarket, which asks its members to de-list from at least one of the ‘big two’ online players – the other being Rightmove.

“Four fund managers, Tremblant Capital, BlackRock Investment Management, Ennismore and GLG Partners, clearly believe the pain Zoopla detailed in its accounts in February will continue, and are shorting the stock.”

Normally, when stock is being shorted, the share price falls.

But yesterday, Zoopla’s shares finished at 196p, continuing the upward trend that began in the middle of March.

Rightmove, meanwhile, continued its trajectory since the start of the year, closing at 3,143.
