The offer will make it cheaper for investors to buy shares which they identify as being bargains as worldwide stock market trends drive down some prices.

Recent research from Alliance Trust has revealed that 38% of online investors are prompted to trade by world events that they think will affect share prices. The survey of more than 1,000 online investors found that men are much more likely to react to world events with 41% stating it as a trigger to trade while only 27% of women claim to be influenced by the outside world.

Men also prefer to follow stock tips from the papers and the internet while only 28% of women rely on tips in papers with 19% looking online. However, women are more likely to take investment advice from family or friends while men are less inclined to ask for help.

Claudia Philips, managing director of investment dealing at Alliance Trust, commented: While major falls across global markets clearly spell bad news overall, they can throw up selective share-buying opportunities for smart investors.
