The chief financial officer at Purplebricks and the wife of chief executive Michael Bruce bought shares worth £2.8m for less than £20,000 last Friday.

Chief financial officer Neil Cartwright bought 1.9m shares for 1p – a tiny fraction of Friday’s share price which closed at 141.5p.

It means the 48-year-old paid £19,400 for a holding currently worth around £2.8m.

Isabel Bruce, 32, a human resources administrator, paid £426 for shares worth £60,500.

Cartwright and Bruce were granted options to buy stock in the business at a discount as part of the company’s remuneration policy.

It takes the Bruces’ holding to 16.9% of the stock, worth £20.3m in total, while Cartwright owns 0.8%. The pair will not be able to sell the stock until December.

Yesterday, Purplebricks’ share price shot up at one time during trading to 150p – and could double, according to one broker.

Peel Hunt initiated coverage of Purplebricks yesterday, giving it a ‘buy’ rating and a price target for the shares of 300p.

However, despite the recommendation, the shares ended the day at 143.50p, just 2p up on the opening price.
