Purplebricks shares dipped yesterday after issuing a trading update saying that it expects revenue to rise around 445% to £18.5m to the year ended April 30.

Purplebricks also said it was on track to meet its full-year expectations.

Investors, who normally buy into just those expectations, seemed unimpressed, however, possibly over the update’s silence on its profits and costs.

Analysts also seemed uncertain.

Anthony Codling, of Jefferies International, said that without knowing how many properties the company had actually sold, it was difficult to gauge performance.

At one stage yesterday, the shares fell 13%, but recovered somewhat to end the day at 164.75p. On Monday, the shares were at an all-time high at 180p.
