Analysts at Piper Jaffray yesterday repeated that firm's "outperform" assessment on Apple's stock.

Piper Jaffray issued a target stock price of $52 per share, observing improved production efficiency because Apple now manages to ship most products on the same business day.

Demand remains strong for Apple products, the report adds, citing the number of such products featuring in Amazon US' Top Ten lists as proof.

Apple shares are currently trading at $36.42, and fell 55 cents on news of Yahoo's debut into the online music market yesterday.
