Today, the Dow
Of the 30 Dow components, 23 were down today. Four of them were down more than 1%.
Stock Price (Daily Price Change)
The market as a whole reacted negatively to an unexpected new-home-sales decline for December. New-home sales fell 2.2% to a seasonally adjusted annual rate of 307,000. For 2011 as a whole, sales fell 302,000 -- a 6.2% drop and the worst annual sales total on record.
Of course, if you're looking for a housing bottom, this could be good news, as my fellow Fool Morgan Housel explains.
But the biggest daily loser, AT&T, had the most identifiable reason for being down. Its earnings report today disappointed folks just as Verizon's did two days ago. Excluding charges, it reported earnings per share of $0.42, a penny off from analyst estimates. But including all one-time charges, it reported a loss of $6.68 billion, or $1.12 per share.
AT&T took a $4.2 billion charge from its failed bid for T-Mobile USA, but like Verizon, the longer-term problem for AT&T is its dependence on Apple. Even with efforts to diversify, some 80% of its smartphone sales were iPhones. Remember that these are extremely subsidized by the carriers to lock in customer contracts. And now that the iPhone isn't exclusive to AT&T, the subsidies go from differentiator to table stakes.
There you have it -- a bad day for AT&T and, more importantly, a sign of potential long-term trouble ahead if it can't solve the margin sucking sound coming from Apple.
