House builder Galliford Try has gained a whopping 52% in the last 12 months, catching the eye of Tempus in The Times.The impressive price performance has come, says Tempus, on the back of a gamble on land prices in 2009 when the company raised £120m to go on a buying spree, mainly in the south and south east of the UK when prices were depressed.That now looks like an immensely good decision with selling prices up around 17% in the last year.Galliford's construction business is not quite as stellar with the company willing to shrink the order book to maintain margins. The shares currrently trade at 9 times earnings, however, and Tempus thinks, for the long term, they are worth a buy.Meanwhile, Questor, the Telegraph's shares analysis column, tips J Sainsbury. The argument is straight-forward. The supermarket chain is paying a prospective dividend of 5.5% to March 2013. That's big whichever way you look at it.With the stock down 25% since 2010 and the group having a very healthy Christmas, with like-for-like sales excluding fuel up 2.1% in the 14 weeks to January 7th, there is a strong chance for capital growth. Questor says buy.bsPlease note: Digital Look provides a round-up of news, tips and information that is impacting share prices and the market.
