Sprint declined after the wireless carrier retreated from its offer for T-Mobile US after two months of lobbying failed to clear regulatory hurdles; Twenty-First Century Fox gained after rescinding its $80 billion bid to purchase Time Warner. Walgreen fell after the drugstore chain said it would not use its acquisition of Europe’s Alliance Boots to move its headquarters overseas.
