(Sharecast News) - London's FTSE 100 was down 0.8% at 9,835.85 in afternoon trade on Thursday.
Convatec surged to the top of the index as it hailed strong sales growth in the 10 months to October end and said it was on track to deliver FY25 and medium-term financial targets.
Precious metals miner Fresnillo shone as gold prices rose.
Persimmon gained as the housebuilder reiterated is full-year outlook despite "challenging" market conditions, after a jump in sales and prices.
On the downside, 3i Group tumbled even as the private equity and infrastructure investment firm said it had delivered a strong investment performance over the first half to 30 September, helped by solid gains from long-term hold asset, Action.
Russ Mould, investment director at AJ Bell, said: "The fortunes of private equity investor 3i are heavily tied to Action, with the company continuing to increase its stake in the Dutch discount retail chain.
"This has largely been a good news story for the group as Action has achieved significant growth in recent years.
"However, today's numbers were a little short of expectations. The company warning of an uncertain backdrop will raise concerns about the outlook for Action and its wider portfolio."
Insurer Aviva was also weaker, pulling back after a surge so far this year, as new medium-term profit and return targets underwhelmed investors, despite the company delivering on financial targets a year earlier than planned.
Flutter Entertainment fell as the Paddy Power owner cut its full-year profit forecast.
Sainsbury's and Coca-Cola Europacific Partners were both down as they traded without entitlement to the dividend.
