Rexam, maker of cans and plastic packaging for anyone from Coca-Cola and Heineken to US consumer products manufacturers such as Procter & Gamble, wants to achieve a return on capital employed of between 12% and 15% over the next three years.

While potential investors may take comfort in Flybe's modest forward earnings ratio of 7.6 and its objective to expand across continental Europe, its reliance on the still fragile UK economy makes us think that this calamitous flotation remains fraught with risk, and may suffer further turbulence in the months ahead.

The valuation, which, at 1.6 times net asset values, according to Numis, is hardly prohibitive. At spot gold prices, that multiple falls to 1.1 times, according to Canaccord Genuity, says the newspaper, which recommends buying the shares.The engineering and construction company Costain looks like it's in pretty solid shape despite recent market turmoil, with yesterday's update showing that it had secured £850m in revenues for 2011. Moreover, the group has more than £100m in cash on the balance sheet and no significant borrowings to speak of. In other words, the picture looks rather rosy. That, coupled with an affordable forward-earnings multiple of under 9 times, makes this a stock worth buying, in our view.
