The S&P 500's Biggest Movers

The S&P 500 snapped a two-week losing streak last week, rising 3.2% to 1,069.3, despite a rise in the unemployment rate to a 26-year high. A rosy outlook from Cisco combined with a strong productivity number, positive retail sales in October, and positive data on the manufacturing sector to pull the market higher during the course of the week.

Let’s take a closer look
It was Merger Mania last week as both Black & Decker and Burlington Northern agreed to be acquired. Black & Decker, which makes power tools, was acquired by hand tool company Stanley Works in a $4.5 billion all-stock deal, as both companies try to rein in their costs going forward.

Perhaps the biggest chatter last week was stirred by Warren Buffett’s Berkshire Hathaway, which purchased a remaining stake in Burlington Northern Santa Fe. Buffett, already a partial owner of the railroad, bought the remaining 77% stake in the company for a 31% premium of $100 per share. Buffett has called the deal a bet on the long-term health of the U.S. economy. He also favors railroads because they are insulated from overseas competition, unlike the auto and manufacturing industries.
