High profile fund manager Neil Woodford, who owns over a quarter of Purplebricks’ shares, has endured a tough start to 2018, after his flagship fund plummeted by £1bn in value in the first five weeks of the year.

The Woodford’s Equity Income fund fell from £8.2bn at the start of January to under £7.2bn on Tuesday this week.

Stakes in Purplebricks, whose share price was dented by a bombshell report from Jefferies analyst Anthony Codling, and outsourcer Capita, whose share price has also been under pressure following the collapse of Carillion, were the driving force behind the poor performance this year, according to City AM.

The fund also has a stake in troubled doorstep lender Provident Financial.

Last August, shares in the Bradford-based Provident fell by almost 70%, one of the biggest ever one-day sell-offs in FTSE 100 history.

Woodford’s fund also shrank £2bn in value between last May and December, the publication has reported.

A spokesman for the fund manager said: “Neil’s funds have at times underperformed the broader market because of a contrarian view.

“This is not the first time his funds have suffered redemptions.”

Purplebricks’ share price has dropped around 15% since the end of January, when it was at 489.8p

It closed yesterday at 412p, down 1.44% for the day.
