Q3 Apple Earnings: Hold and Wait for the Boom

Well, nobody is buying Apple’s conservative estimates for this quarter. Certainly not after the release of the latest Mac sales data from NPD Group this morning. Analysts had been calling for Apple to sell 2.45 million Macs in its third quarter. Instead, NPD says the company sold approximately 2.6 million.

That’s a 16 percent spike, a far cry from the flat to five percent increase analysts had been anticipating. And if NPD is accurate, it means Apple has just had its best-ever June quarter for Mac sales.

Add to this indications that sales of the iPhone 3GS are tracking ahead of even Apple’s and AT&T’s expectations–remember, AT&T (T) said this year’s iPhone launch was its best-ever retail sales day and the largest ATT.com order day in the company’s history–and the quarter’s looking pretty damn good, even if the Apple’s iPod business is slowing down a bit.

So what can we expect? Apple (AAPL), known for giving conservative guidance, has said it expects earnings per share of between 95 cents and a dollar. Analysts are more optimistic. Consensus, as reported by Thomson Financial, calls for $1.16 per share. And folks like Andy Zaky over at Bullish Cross are betting on $1.35. Who’s right? We’ll find out tomorrow when Apple reports after market close.
