Bank of America Merrill Lynch raised the builders' merchant to Buy from Neutral. ----------OTHER MAIN MARKET AND AIM - WINNERS----------Tekcapital, up 65%. The intellectual property investor said its portfolio company has launched a low-sodium salt under the name MicroSalt. The portfolio company, Salarius, develops and manufactures MicroSalt - salt crystals that are around 100 times smaller than table salt. These smaller grains produce a more powerful flavour, which means less sodium is consumed overall. In addition to the MicroSalt launch, Salarius has "secured its first customer to incorporate MicroSalt in their snack food business". The customer, whose name was not disclosed, is a US snack food maker, and the MicroSalt will be dispatched to it in May. Tekcapital owns a 97.5% stake in Salarius.----------Thomas Cook Group, up 17%. The travel agent's shares were higher after Sky News reported on Saturday that the company is in talks over a possible takeover. Sky said it learned that Thomas Cook has "brought in advisers from AlixPartners to work on its balance sheet and cost reduction plans, while its syndicate of more than a dozen lenders has hired FTI Consulting to advise on their financial exposure to Thomas Cook". Fosun, a Chinese company and Thomas Cook's largest shareholder, is reported to be "among those which have lodged a preliminary interest" in buying Thomas Cook's tour operating business. According to Sky: "Analysts also cited EQT and KKR, the two private equity firms which own Kuoni Group and Travelopia respectively, as logical bidders for the London-listed travel company".----------
