Ocado Group shares leapt almost a third on Friday after Morrison Supermarkets confirmed the two are teaming up to launch its first shopping website in January next year. The partnership had been expected as the two have been in talks since Morrison announced it was moving online in its annual results in March. Online grocer Ocado will provide its technology, logistics and distribution operations to Morrison. Alent, supplier of specialty chemicals and engineered materials, reported a 5.8 per cent fall in net sales value (NSV) in the first quarter. NSV came to £101.8m, down from £108.1m a year earlier, reflecting lower smartphone, personal computer and semiconductor wafer start volumes. Thomas Cook was retreating one day after Prime Markets labelled the travel agent as a 'buy', hailing the new strategy of Chief Executive Officer (CEO) Harriet Green.
