Stocks suffered a turkey-induced hangover today, with the Dow Jones Industrial Average (^DJI -0.98%) and the broader S&P 500 (^GSPC -0.46%) losing 0.3% and 0.2%, respectively. The Nasdaq, however, bucked the trend, gaining a third of a percentage point. Today was all about big-cap tech:

The micro view: Facebook (META -10.56%) jumped 8.1% to a four-month high on an upgrade from Sanford C. Bernstein. Sanford's analyst raised his price target from $23 to $33, arguing that the social network will generate revenues of $7 billion next year -- well ahead of the $6.4 billion consensus estimate. Even excluding today's gain, Facebook shares were up 35% from their Sept. 15 low closing price of $17.73. With the stock experiencing a remarkable reversal in momentum and Sanford Bernstein blazing the trail, I think we can expect to see a flurry of analyst upgrades in the days and weeks to come. Nevertheless, I would caution investors not to try to anticipate, game, or time these events -- that's a trader's bread and butter and has nothing to do with investing.

E-commerce stocks including Amazon.com (AMZN -1.65%) and eBay (EBAY 0.31%) also did very well today on the back of strong numbers from the Thanksgiving weekend/online Monday shopping period. However, I think the more interesting story from Amazon is that the online retailer is set to do its first bond issue in more than a decade. Does the company need the cash? No: The company is cash-flow positive and has more than $5 billion in net cash on hand. Why the offering, then? Because the cost of issuing debt for governments and corporations is at a historic low. This is smart capital management and is consistent with Amazon's long-term approach to value creation.
