The Talkin’ Cloud Stock Index has generated flat performance from December 17 through December 23 (U.S. markets are closed December 24), but the index is still up a rather lofty 49 percent so far this year. This week’s biggest weekly winners only showed small gains, and the weekly losers only fell a few percentage points.

Among the Talkin’ Cloud Stock Index members worth noting:

Constant Contact, Inc. (NASDAQ: CTCT, up 3.97% this week), the SaaS-based email marketing specialist, keeps its stock momentum of recent weeks with no obvious inciting factor spurring its respectable climb.

Amazon (AMZN) is on the Talkin’ Cloud Stock Index because of it’s Amazon Web Services business – but the 2.82% rise this week likely involves consumers flocking to Amazon’s e-tailing site. Still, we have noticed more channel strategies involving Amazon Web Services. Oracle recently made its software available in Amazon’s cloud, and Former OnForce CEO Jeffrey Leventhal leverages Amazon Web Services for his latest channel startup: Work Market.

Meanwhile, Taleo (TLEO) continued it’s downward trend, though it shows signs of slowing: almost 11% lost last week versus a 2.39% drop for the trading week ending December 23rd. Unfortunately, no cause for the drop is immediately forthcoming. Rackspace (RAX) also had a mild dip this week.

Whether you buy, sell, or hold is up to you. Generally speaking, we update the index after U.S. financial markets close each Friday. This week, we performed the index update on Thursday because of the approaching holiday weekend.
