What to Expect From Tech Earnings

We've got a big week for earnings coming up, including big techs and a few others:

In tech, Yahoo and Intel report Tuesday.

At Yahoo, the Street is looking for $1.1 billion in revenue, 24 cents EPS. The number to watch is display ad revenue. Yahoo's stock for the first time this year has been climbing the cliff it fell off in 2008, on optimism over CEO Marissa Mayer's turnaround prospects. But now the actual numbers behind the company's performance will get even more important, since investors are placing some value on the company again, not just its Asian investments.

At Intel, we'll see the toll of the vanishing PC. The Street is looking for $12.6 billion in revenue, 41 cents EPS. With PC sales in a historic slump, down nearly 14 percent from last year, according to IDC, Intel's PC client business revenue is bound to be tepid at best.

Keep in mind, Intel is also prepping for a new CEO announcement before June—so investors will be especially keen to hear signals on where growth might come from and where gross margins are trending. Tablet and phone efforts so far have fallen flat.

EBay reports Wednesday, and PayPal should get most of the attention: Analysts want $3.76 billion in revenue, 62 cents EPS.

Thursday we have a stacked day of Nokia, Google, IBM and Microsoft. For Nokia, investors will want evidence that Lumia smartphone sales are holding their own beyond the holiday season, though Nokia already warned not to expect a profit.

Especially with Microsoft and IBM, enterprise spending trends will be among the big takeaways, where we'll see if the headwinds that Infosys and Oracle have faced are widespread. And the Google numbers will show Motorola integration progress (or lack thereof), handset sales, and the staying power of Nexus tablet sales. Any of those could weigh on margins and EPS, though strength in Google's core business has managed to counterbalance those effects so far.
