Rio Tinto, up 1.1%, Anglo American, up 1.0%, Glencore, up 0.8%, BHP, up 0.5%. The internationally-exposed miners were higher on hopes a fresh round of tariffs on Chinese goods set to come into effect on Sunday will be postponed. On Tuesday a report in the Wall Street Journal said US and Chinese officials were working on a deal to postpone a round of tariffs set to hit Chinese imports. However, US President Donald Trump's top economics adviser Larry Kudlow warned the measures remained in play for now, although he did say that Trump had struck a "constructive and optimistic tone" on China. "We expect the tariffs will be postponed, as Trump cannot risk another period of escalation hurting the US economy ahead of the upcoming presidential election next year," said Danske Bank.

Riverstone Energy, down 6.5%. The oil and gas company sold all of its offshore Gulf of Mexico assets owned by subsidiary Castex Energy 2014 to Talos Energy. Riverstone also is offloading the undrilled primary term acreage and prospects of ILX Holdings III to Talos. Riverstone owns 25% of Castex and 33% of ILX - having invested USD52 million and USD155 million in the two companies, respectively. Riverstone didn't provide the price that Talos is paying. The deal is expected to be funded by the issuance of new Talos shares and existing Talos cash.

Kromek, up 8.7%. The detection technology firm reported a "record" revenue figure for the interim period. Revenue in the six months to October 31 was GBP5.3 million, 43% higher than a year before. The pretax loss widened to GBP2.7 million from GBP2.1 million, however, due to increased finance and operation costs. Sedgefield, County Durham-based Kromek said revenue growth came due to multi-year contracts signed with commercial and government customers across the world, in nuclear detection, medical imaging, and security screening. Looking forward, Kromek has "increasing commercial momentum", with revenue and earnings before interest, tax, depreciation and amortisation for its financial year to April on track to meet the market's expectations.

Rosslyn Data Technologies, down 14%. The data technology company said it expects annual results to be in line with forecasts despite a slow start to the year. Rosslyn said it had a slower than hoped start to sales in the first few months of its current financial year, which started in May, with professional service revenue hurt by some clients deferring contracted projects. In addition, Rosslyn said it has decided not to renew client contracts with a high element of resale revenue, as these were unsustainable due to low levels of gross margin.
