Bayer Snares Merck Unit as Global Indices Waver

European and Asian stocks struggle to gain direction on Tuesday, with mixed trading on both continents. In Germany Bayer strikes a $14.2 billion deal to buy the over-the-counter pharmaceuticals unit of Merck, and in London major constituents of the FTSE 100 pull the index down as trading resumes after Monday’s public holiday. Among the losers Barclays falls after weak first-quarter numbers and AstraZeneca declines as it launches its defense against Pfizer’s $106 billion bid.
