Analysts at Needham & Co and Goldman Sachs last week raised target prices on Apple stock, predicting surging Mac and iPhone sales.

Needham & Co offered a "buy" rating on Apple stock with a $235 price target, saying surging sales of the Mac and the iPhone will drive the second chapter of its growth story.

"The iPod is yesterday's news. Now the Apple story is all about the Mac and the iPhone," Needham analyst Charlie Wolf wrote, predicting Apple will seize 7 per cent of the worldwide computer market in the next decade.

Wolf further described the iPhone as the "gold standard of the mobile content market".

Goldman Sachs hardware analyst David Bailey advised investors to stay long on the stock in the prelude to Apple CEO Steve Jobs' 15 January keynote speech, raising his target price $15 to $220.

Bailey predicted new sub-notebook Macs, film rental services and other additional content for iTunes-enabled devices.

Despite the positive assessments, Apple lost more than $14 on Friday's trading, in common with all tech stocks, as investors begin to consider the further impact of losses in the sub-prime lending market and continued slow growth in US employment figures.
