Davis, Polk & Wardwell and Wachtell, Lipton, Rosen & Katz have steered multiple big deals announced in the last week. Meanwhile, Davis Polk, Latham & Watkins and Lowenstein Sandler worked on the largest announced deal of the past week, a $10.6 billion buy of Altair Engineering by Siemens.

It was the last full week before a U.S. presidential election that pits two different economic policies against one another, creating a level of uncertainty in the deal market.
