London’s FTSE 100 index gave back earlier gains towards the London close, finishing the day down by 0.1%, or 5.67 points, at 7,321.72, underperforming its European peers. The FTSE 250 ended on a more positive note, up by 0.4%, or 65.46 points, at 17,083.05, while the AIM All-Share closed up by 0.2%, or 1.28 points, at 679.85.

BP, still recovering from the sudden departure of its CEO in September, announced a $1.5 billion share buyback for the third quarter. However, this move wasn’t sufficient to prevent its shares from sliding by 4.5% as its underlying replacement cost profit fell to $3.29 billion, missing the market consensus of $4.01 billion.

Despite this setback, BP reported an increase in its underlying RC profit compared to the second quarter, citing higher refining margins, increased oil and gas production, and a strong oil trading result, partly offset by a weak gas marketing and trading performance. The company expects an increase in upstream production for the year overall.

The decline in BP’s shares was exacerbated by a drop in oil prices, impacting industry rival Shell, which fell by 1.9%.

Vodafone and Zegona Communications confirmed a €5 billion deal for the sale of Vodafone’s Spanish operations.

Vodafone shares fell by 1.4%, while Zegona’s shares remained suspended from trading.
