(Sharecast News) - London's FTSE 100 was up 0.2% at 9,163.61 in afternoon trade on Wednesday.
Spirax Group was the top gainer again, having surged on Tuesday on the back of better-than-expected first-half results.
Specialist insurer Beazley tumbled as it posted a drop in first-half profit and cut its full-year premium growth guidance.
"The firm highlighted climate change and technology as two key issues that are undermining predictability for the insurance industry, and which undoubtedly make things tricky for any company which is in the business of pricing risk," said Russ Mould, investment director at AJ Bell.
Hiscox also lost ground.
Housebuilder Persimmon slumped after saying it still expects to deliver between 11,000 and 11,500 completions for the full year despite challenging market conditions and the prospect of tax rises in October's Budget.
The company said its private forward order book was up 11% to £1.25bn, while underlying pre-tax profits for the six months to June were also up 11%, to £165m.
