The City's interest in the wild and wonderful world of construction continues. As housebuilders wait eagerly for news of another interest rate cut, investors are quietly buying up shares. More companies finished off the week higher than they started.

It seems the suits are starting to realise that companies such as Carillion, Persimmon and Jarvis are bargain buys, and the smart ones are trying to get in on the ground floor.

As one analyst (with a slight air of disbelief) confirmed: "There is genuinely more interest out there. It's very pleasing." Even with this added appetite, of course, many of the shares are still greatly undervalued.
