London's Alternative Investment Market has been the best-performing stock market in the world so far this year, according to London stock market figures.
Aim's value increased by 130 per cent between the start of the year and the end of last week. It says growth was underpinned by the widely reported surge in private investment in high technology and smaller companies.
The growth of Aim flies in the face of the FSA who warned urged private investors more caution when trading in “volatile” high technology shares.
But some commentators remained cautious. Winterflood Securities' Julian Palfreyman says: “Volumes are higher, but so is volatility. The herd is all a buyer at once or all a seller at once.”
