Stocks set for lower open

   Futures drop ahead of Bank of America's quarterly results. Pepsi bids for 2 main bottlers.

LONDON (CNNMoney.com) -- U.S. stocks were poised for a lower start Monday, as jitters about corporate results overshadowed deal news.

At 5:26 a.m. ET, Dow Jones industrial average, Standard & Poor's 500 and Nasdaq 100 futures were all lower.

Futures measure current index values against perceived future performance and give an indication of how markets may open when trading begins in New York.

Earnings: With an estimated 10% of the S&P 500 having reported results so far, profits are on track to have shrunk 37.4% from a year ago, according to the latest from Thomson Reuters. 

About 140 companies, or 28% of the S&P 500 report results this week. In focus Monday is Bank of America (BAC, Fortune 500), which releases its financial results before U.S. markets open.

In the drugs sector, British firm GlaxoSmithKline (GSK) agreed to pay up to $3.6 billion for independent skincare specialist Stiefel Laboratories. Stiefel is partly owned by private equity firm Blackstone Group (BX).

World markets: Stocks in Asia managed to end mostly in positive territory. Japan's Nikkei edged higher and the Hang Seng in Hong Kong rose nearly 1%. European markets, meanwhile, tumbled in morning trading.
