If you ever thought the efficient-market hypothesis worked well, today should dissuade you. Sure, the stock market got a bump from the Federal Reserve's decision yesterday to implement the long-anticipated QE3 bond-buying program. But today's move just looks like more follow-through from Fed-related bullishness, as if something about the third round of quantitative easing makes investors think it will work better than the first two. Regardless, the Dow Jones Industrials (INDEX: ^DJI) roared higher, rising more than 100 points before settling back to a more modest 74-point gain at around 10:45 a.m. EDT.
Among Dow stocks, the big news of the morning came when the committee overseeing the Dow decided to replace Kraftwith UnitedHealth Group. The change will take effect after next Friday's close.
As you've probably come to expect on a big bull day for the Dow, economically sensitive stocks led the way higher. But missing the wave up were pharma stocks Pfizer (NYS: PFE) and Merck (NYS: MRK) , which dropped 2% and 1.5%, respectively. Neither company had any apparent news justifying the move, but one explanation may simply be that pharma stocks are seen as more slow-growth, defensive names that aren't likely to perform as well in a big bull-market rally as more volatile, high-growth stocks.
AT&T (NYS: T) and Verizon (NYS: VZ) also lost ground, both dropping around 2% after a Stifel Nicolaus analyst downgraded both stocks. The analyst cited earnings pressure from the iPhone 5 release, which led him to reduce full-year profit estimates for both companies. Yet while AT&T and Verizon may take an earnings hit in the short run, the iPhone could easily produce blockbuster long-term profits, especially if the companies' efforts to beef up revenue from their data plans bear fruit.
