Stocks posted solid gains Monday, adding to last month's big advances and pushing the Dow Jones industrial average into positive territory for 2015. Several companies moved on news, including Chipotle Mexican Grill, and Visa. Health care stocks were among the winners as drugmakers Pfizer and AbbVie climbed, while energy stocks rose sharply in a late-day rally. The Dow Jones industrial average rose 165.22 points, or 0.9%, to 17,828.76. The gain made the Dow the last of the three major US market indexes to return to positive territory for 2015.
The Standard & Poor's 500 index rose 24.69 points, or 1.2%, to 2,104.05 and the Nasdaq composite rose 73.40 points, or 1.5%, to 5,127.15. Health-care stocks continued to rally. Drug giant Pfizer rose $1.24, or 3.7%, to $35.05, the second-biggest gain in the Dow. The shares slumped late last week on word Pfizer is in talks to buy competitor Allergan. AbbVie, which surged 10% Friday on strong third-quarter results, climbed $3.83, or 6.4%, to $63.38 after analysts at Morgan Stanley upgraded the stock. Health-care stocks gained 2%, nearly twice as much as the broader S&P 500 index. Energy stocks rose even more, 2.4%. Exxon Mobil, Chevron, Chesapeake Energy, and others rose 3% or more.
