Banc of America analyst Keith Bachman has revealed what he calls poor Mac sales in January.

Citing NPD data, he reveals that Apple's revenue and unit sales grew just 1 per cent and 6 per cent respectively in January, year on year.

Forbes compares this to revenue growth of 25 per cent and unit growth of 20 per cent in the December quarter.

The analyst observes that Apple's Intel iMac didn't ship until January 10 and MacBook Pros didn't reach market until February.

Bachman has a "neutral" rating and $82 price target on Apple shares, the report explains.

"We believe that the stock will trade well into product announcements next week, which we believe will include a low-end notebook," he said.
