J.P. Morgan has raised its estimates for Apple, citing robust sales of Macs and iPods through December. Analyst Bill Shope said in a research note that the “key catalyst” for the increase was “improved availability of 1-inch drives for the iPod mini.” The firm expects earnings per share of 49 cents for the December quarter, up from its previous estimate of 47 cents. J.P. Morgan also raised fiscal 2005 forecasts, now predicting EPS of $1.71, up from $1.69.
