Market Watch: Aggreko boss facing questions over US performance

But Alex Magni, an analyst at HSBC, thinks the “soft” second-quarter growth from the United States unit was an “aberration” and did not signal a slowdown. Caroline de La Soujeole, an analyst at Seymour Pierce, expects Aggreko to post underlying interim pre-tax profits of £142.4 million, up 18 per cent.

Analysts at Peel Hunt believe Moodiesburn-based sausage skin maker Devro will report a 6 per cent rise in interim pre-tax profits to £20.3m on Tuesday, helped by increased sales of its higher-margin products.

Wolfson, the Edinburgh-based microchip maker, will have to rely on strong sales of key devices, including Samsung’s SIII mobile phone, in order to offset “broader patchy consumer demand” when it reports its interim results on Tuesday, according to Peel Hunt analyst Alex Jarvis.

An inquiry by the US senate earlier this month found that banking giant HSBC had inadvertently dealt with terrorist financiers, money launderers and drug cartels.

The lender’s half-year results tomorrow may make a provision against some of the estimated $1 billion (£642m) costs of the scandal.

Energy giant BP will show the effect of falling oil prices and lower output when it reports interim figures on Tuesday. Experts predict the group will post an 18 per cent drop in underlying profits to $9.2bn.

Defence manufacturer BAE Systems is tipped to suffer a further fall in profits on Thursday. Jefferies analyst Sandy Morris predicts revenues will fall 4 per cent to £8.8bn in the six months to 30 June.
