Apple stock hits 52-week high

Steve Jobs's MacWorld speech yesterday seems to have injected some magic into Apple's share performance.

The company's stock hit a 52-week high in early trading today, jumping a further 11 per cent to 29.25 and besting the previous high of 27.75.

Several analysts upgraded Apple to 'buy' ratings, reversing the battering the stock had taken before Jobs became linked with a seat on the Apple board.

Even London brokers reported heavy trading on Apple's stock, according to Reuters.
