On Monday Piper Jaffray analyst Gene Munster issued a note to clients containing his concerns over Apple's Mac sales during its third fiscal quarter of 2009. Munster's note told clients that preliminary computer shipment data from NPD due Monday afternoon would be key to his expectations of Apple shipments for the quarter which the Street expects to be around 2.45 million.
"Mac NPD for the month of June needs to be flat in order for the entire quarter to be tracking in line with Street Mac consensus,"
A few hours after the note NPD released data suggesting that Mac sales were up 16% in the quarter, following this Munster released a second note adjusting his prediction to 2.6 million Mac units during the quarter.
