Health-care companies rose amid deal activity.

British drugmaker GlaxoSmithKline agreed to buy Sierra Oncology for $1.9 billion, as it builds out its cancer-drug business with a producer of a treatment for patients with a rare bone-marrow cancer. Halozyme Therapeutics agreed to buy specialty pharmaceutical company Antares Pharma for almost $1 billion in a move that will deepen its focus on drug delivery.

Health insurer Humana rose after analysts at brokerage UBS boosted their rating on the company's shares, saying its Medicare business would soon return to "above industry growth levels."
