The FTSE 100 fell 0.1% with heavyweight financials leading declines. A fifth month of consecutive gains would be the index’s best winning streak since 2016. Retailers slipped 0.3% as growing costs linked to COVID-19 and Brexit might add to the rise in broader inflation soon, an industry group said. The domestically focussed mid-cap index was flat. Among stocks, Dixons Carphone dropped 0.4% even after the electricals retailer reported a 34% rise in annual profit. Opioid addiction treatment maker Indivior Plc jumped 10.8% to the top of the FTSE 250 index after it said its 2021 revenue and profit would be significantly above its previous outlook.
