Apple's Peak, Google's Valley: Tech Winners & Losers (Update 2)

Updated from 1:06 p.m. EDT to provide closing stock prices in the last paragraph.

NEW YORK ( TheStreet) -- Apple ( AAPL) shares were gaining Monday after an analyst raised earnings estimates into the March quarter. Apple was up 0.31% to $424.51.

Canaccord analyst T. Michael Walkley raised earnings estimates on Apple due to stronger iPhone 4 and iPhone 4S sales. Walkley increased his iPhone estimates for the current quarter to 37 million units from 34.5 million units, and did the same for the June quarter, raised to 27 million units from 25 million.

"Our March quarter global handset surveys indicated the iPhone 5, 4S, and 4 maintained leading share of the high-end smartphone market with improving supply and a stronger mix of iPhone 4 and 4S sales than our expectations," Walkley wrote in a note. He raised his full year 2013 and 2014 estimates for Apple as a result, with 2013 earnings moving to $43.86 a share, up from $43.59 a share. Walkley's fiscal 2014 earnings estimates were bumped up to $50.16 a share from $50 a share.

Google ( GOOG) shares were off 1.57% to $770.73 as rumors suggest the Internet search giant may spend $1 billion to acquire the messaging application, WhatsApp.

Industry Web site Digital Trends said Silicon Valley-based WhatsApp, which is popular in emerging markets, has been negotiating with Google for several weeks. The company is reportedly trying to get a better price well aware that Google seeks to continue to monetize mobile.

WhatsApp charges 99 cents, and keeps its services ad-free. Google does not currently have a high-profile mobile messaging app to counter Apple and Facebook ( FB) which do have one.

Facebook ( FB) shares were giving back some of their recent gains, losing 2.37% to $26.74 after the company unveiled Facebook Home to the public last week.

Facebook Home includes new features, such as Chat Heads, Notifications, Cover Feeds, and App Drawer. Everything is designed to make navigation, engagement, and use much easier and friendlier.

Facebook Home: A Google Killer

A leaked download of the beta version of Facebook Home appeared on the Internet Monday. The official app, available for Android, will be on Google Play, come April 12.

Update: Facebook killed the leaked beta version of Facebook Home. MoDaCo founder Paul O'Brien, who first reported the leak, has tweeted the beta has been killed.

Closing prices: AAPL closed up $3.01, or 1%, at $426.21; GOOG fell $8.20, or 1.5%, to $774.85; and FB was down 54 cents, or 2%, at $26.85.
