The FTSE 100 Index hit a fresh 30-month high today as it chalked up gains for the seventh consecutive session.

The fallout from the quake in Asia continued to have a psychological impact on markets, although shares in Zurich-based reinsurance giant Swiss Re advanced 39p to 3737p in London after it said it expected claims from the disaster to total less than 100 million francs (£45.9m).
Economic news at home also held back progress, with the Nationwide saying house prices fell by 0.2% this month.
On the markets, the maker of Durex condoms and Scholl footcare products was lifting the mood as traders continued to speculate about a possible takeover.
SSL International was the second highest riser in the FTSE 250, up more than 6% or 18p to 314p, as dealers mulled over talk of interest from companies such as household products giant Reckitt Benckiser.
One of the top flight climbers was drugs giant AstraZeneca, which shook off earlier losses to close 10p higher at 1890p, following yesterday’s news of Japanese approval for its cholesterol-busting drug Crestor.
Drinks companies featured among the top flight risers, with SAB Miller advancing 6p to 867p and Scottish & Newcastle up a penny to 435p.

Back outside the top flight, telecoms company Spiritel added 2.5% or half a penny to 20.5p as maiden results showed losses in line with expectations. The firm vowed to cash in on the trend to move call centres abroad through a new division.
Shares in support services group Jarvis lost earlier gains to fall 24% or 9p to 28p despite chief executive Alan Lovell’s predictions of a long-awaited recovery. The stock had doubled in value after yesterday’s half-yearly results.
