Rightmove needs to do very little to stay as successful and as dominant as it is, says financial website The Motley Fool.

Certainly Rightmove’s long-term shareholders must be remarkably grateful for a strategy that includes almost daily share buy-backs by the company, named this week as the world’s most successful property portal.

Indeed, during the first half of this year, it used dividends and buybacks to return 82% of its operating profit, or £66m, to shareholders.

The Motley Fool says of Rightmove: “The company doesn’t need to fund acquisitions or expansion — all it needs to do is maintain the IT and marketing expenditure needed to protect its current position.

“Rightmove has used share buy-backs to reduce its share count from 111.4m during 2010 to just 93.8m today. These buy-backs alone have provided shareholders with an 18.7% rise in earnings per share over the last six years.

“Rightmove has delivered outright profit growth on top of this, of course, but these numbers show how useful buy-backs can be for companies with genuine surplus cash.”

For those still mystified, there’s a fuller explanation here

Essentially, when firms buy back their own shares they send out a message that they are buying into themselves because it’s a marvellous investment. That is usually perceived by the market as an extremely positive sentiment and keeps, or sends, share prices up.

Buy-backs also reduce the number of shares in the market, meaning that earnings per share increase – even if the company does not increase its own profits.

That does not exactly apply in Rightmove’s case. Its pre-tax profits in 2011 were £62.73m; the following year £83.19m; in 2013 £97.02m; in 2014 £122.04m; and last year, pre-tax profits climbed to £137.10m.

Small wonder that Mike DelPrete, a contributor to Property Portal Watch, said that of all the property portals in the world, Rightmove is the most profitable.

This is despite the fact that it does not bring in the most money – the highest revenues are made by US portal Zillow, which last year actually made losses.

Rightmove’s market capitalisation is £3.65bn and last month, on October 4, its shares hit a 52-week high of 4,416p.

But the share price has since slipped until the last couple of days when the shares have seen two strong days, closing yesterday at 3,895p.
