The FTSE 100 closed about 0.4% lower at 9,509 on Thursday, retreating from an intraday record of 9,565.5, pressured by multiple ex-dividend stocks and sharp declines in HSBC and Lloyds. WPP, Barratt Redrow, Tesco, Kingfisher, Taylor Wimpey and Primary Health Properties all fell as they traded without entitlement to the dividend. HSBC slid 5.4%, dragging down the banking sector, after revealing plans to take its Hong Kong-listed unit Hang Seng Bank private and pause share buybacks for three quarters to conserve capital. Lloyds lost 3.3% after the lender warned that it might need to put aside more money than it has already done to pay its share of the motor finance compensation scheme. On the upside, BA and Iberia owner IAG soared to the top of the index, rising 3.2%, following strong quarterly results and a positive outlook from Delta Airlines. Base metal miners also performed well, with Anglo American gaining over 2% on the back of higher copper prices.
