Shares in Purplebricks yesterday endured a bumpy ride on the stock market, as investors showed their displeasure at widening losses.

The business reported a step-up in UK profitability, measured in EBITDA, but group operating losses of £25.6m in the six months to the end of October – more than double its previous six-month operating loss of £11.4m.

The shares were immediately battered, sinking as trading started yesterday morning.

By mid-afternoon, the share price had dropped 15% to 127.5p, with 580,000 more shares traded than normal, suggesting that some backers had decided to off-load their stakes.

The shares ended at around 12% down, to start today’s trading at 131.5p. Major losers were investors in Neil Woodford’s funds.

His 29.2% stake in Purplebricks had £16.4m wiped off its value yesterday.
