A stock market commentator has given his backing to Purplebricks amid questions over the viability of its share price.

Writing on the Motley Fool website, Ian Pierce said the stock is highly valued at the current price, but the online agent could have a bright future if the strategy pays off.

He said: “Since going public in December of 2015, shares of hybrid online estate agent Purlebricks have rocketed 197% in value due to fast growth and huge long-term potential.

“But is disaster around the corner with the company still running a loss, embarking on ambitious overseas expansion and recently tapping shareholders for a £50m rights issue?

“I don’t think so.”

He cited Purplebricks’ falling losses and increasing amount of cash, adding: “While overseas expansion at this stage is risky it also represents the possibility of huge long-term gains. After launching in Queensland and Victoria in August the company already had 50 self-employed estate agents on hand and over £500,000 in sales in just the first seven weeks of operations.

“This tells us that Aussies are finding Purplebricks’ low fixed-fee pricing model as attractive as we have at home.

“Although investors may baulk at being hit up for £50m I reckon they’ll be thankful in the long run as this cash is being used to fund expansion into the massive US real estate market that pays out some $70bn annually in commissions alone.”

Pierce concludes: “Would-be investors should exercise caution because at its current price, Purplebricks is highly valued, which is always dangerous when it comes to loss making disruptors.

“But if its strategy pays off as well as investors currently believe it will, then the future potential is very bright.”
