(Sharecast News) - London's FTSE 100 was down 0.5% at 7,732.27 in afternoon trade on Thursday.
Anglo American, NatWest, Segro and Haleon all fell as they traded without entitlement to the dividend.
On the upside, Informa was the top riser on the index after UBS lifted its price target on the shares to 947 from 933p, keeping its 'buy' rating. It said Informa was a top pick for the year, citing four key areas where it could outperform expectations and increase its valuation.
Berkeley Group and Barratt Developments rallied after FTSE 250 peer Vistry reported a jump in annual profits, unveiled another £100m share buyback and forecast higher completions in 2024 driven by strong demand.
The company posted a 23.2% rise in pre-tax profit of £304m for the year to December.
Vistry said it was on track to deliver strong growth in completions in 2024, targeting more than 17,500 units compared with 16,118 homes built a year ago, underpinned by its forward sales position totalling £4.6bn, of which £2.1bn is for delivery this year
