Rio Tinto's earnings were hit in the first half with big losses in aluminium and diamonds while iron ore and copper profits were scythed. But Rio is cutting $1 billion in costs from its aluminium portfolio and the iron ore JV should deliver more cost savings. If you have a patient long-cycle view of the market, Rio is interesting, says the Times.Kazakhstan-based group Eurasian Natural Resources Corp's (ENRC) shares can hardly be described as cheap - they are trading on a December 2009 earnings multiple of 24.7 times.

The group talks about the quality of films produced by the American studios (punters should wait with bated breath for Jim Carrey's version of A Christmas Carol), and the increasing number of movies being shown in 3D as reasons why investors should be excited. For the Independent it is all about the dividend yield, and for that reason it thinks the investment case is compelling.
