BHP Billiton (BLT) dips 3.4% to £18.89 as its full-year results fall short of market forecasts. Revenues were $66 billion versus consensus of $66.9 billion. The dividend is 1c below expectation at 59c. Numis says the market won't be overly concerned about the small miss, saying BHP is still 'the stand out stock' in the sector. Possibly contributing to the share price decline today is news that a further $2.6 billion will be invested in its Canadian potash project, Jansen. Several shareholders are understood to have put pressure on BHP to delay or scrap the project in light of recent changes to the potash industry which dampens the outlook for the price.

Fellow FTSE 100 miner Glencore Xstrata (GLEN) falls 2.7% to 293.8p despite interim results hitting the top end of its lowered guidance. Pro forma revenue falls 2% to $121.4 billion; adjusted earnings before interest, tax, depreciation and amortisation (EBITDA) is in line at $6 billion. Net debt was $34.8 billion as of 30 June. Glencore has written down the value of assets inherited from buying miner Xstrata by $7.7 billion. The stock is trading on nearly 17 times forecast earnings for the year which looks really expensive given macroeconomic uncertainties hanging over commodity prices.

We discussed the risks presented by over-supplied North American markets in last month's review of the oil services sector and Wood (WG.) appears to have fallen foul of this trend. It slips 7.5% to 834.9p after guiding for weakness in its Canadian business this year and next year. The warning accompanies interim results which show group-wide earnings before interest tax and amortisation (EBITA) up 18.6% year-on-year to $243.2 million.

Shares in housebuilder Persimmon (PSN) slide 0.8% to £11.58 despite strong half-year results which saw pre-tax profit jump 40% to £135.3 million on the back of a 12% hike in revenues.

Cineworld (CINE) may have to sell three sites to satisfy the Competition Commission's worries about December 2012's acquisition of Picturehouse making the enlarged cinema group too dominant in certain parts of the UK. The shares fall 2.4% to 394.75p. Investec reckons 2014 earnings per share could be cut by 1.5% if the three targeted regions must see either a Cineworld or Picturehouse unit sold.

There's no real surprises in John Menzies' (MNZS) half-year results, the shares slipping 1.4% to 748.5p. Aviation is good, distribution is weak. The former business arm is expanding geographically with ground/cargo handling acquisitions being made in Australia and Colombia.

Electronic kit supplier TT Electronics (TTG) again underlines plans for operating margins of between 8% and 10% by 2015, but has its work cut out. Equivalent figures for the half year drifted from 5.6% to 4.9% year-on-year as components sales were squeezed, knocking 3.2% off the shares to 182p. Investors have a 6.7% payout increase while Numis remains upbeat despite top slicing estimates, as does Shares, which flagged scope for a re-rating in June at 151.75p.
