Stocks are rising Wednesday morning as gains in health care and media companies put major indexes on track to set more records. Drugmaker Vertex Pharmaceuticals is surging on positive results from potential treatments for cystic fibrosis. Morgan Stanley is rising after the investment bank’s trading desks had a good second quarter. Cable channel operators Scripps Networks and Discovery Communications are jumping following a report that they could combine.

KEEPING SCORE: The Standard & Poor’s 500 index rose 7 points, or 0.3 percent, to 2,467 as of 10:03 a.m. Wednesday on Wall Street. The Dow Jones industrial average added 27 points, or 0.1 percent, to 21,601. The Nasdaq composite gained 26 points, or 0.4 percent, to 6,370. The Russell 2000 index of smaller-company stocks jumped 9 points, or 0.6 percent, to 6,370. All four indexes have set record highs within the last week.

VERTEX AT THE CENTER: Vertex Pharmaceuticals climbed after it reported strong results from studies of drug regimens that are intended to help hard-to-treat forms of cystic fibrosis. Vertex soared $33.32, or 25.2 percent, to $165.48. That followed a 2.3 percent gain Tuesday after regulators approved a breast cancer treatment the company developed. Vertex’s stock has more than doubled this year and it is trading at all-time highs.

Other health care companies also traded higher. Drugmaker Regeneron gained $9.94, or 2 percent, to $507.57 while health insurers bounced back. UnitedHealth added $2.11, or 1.1 percent, to $188.96 and Cigna picked up $1.65, or 1 percent, to $173.75. Insurers mostly fell Tuesday after the Republican-backed health care bill failed in the Senate.

TRADE WINS: Morgan Stanley climbed after the investment bank said its trading businesses did well during the second quarter, a contrast to rival banks which reported poor trading results as market conditions were quiet last quarter.

Discovery Communications, which runs TLC and Animal Planet, gained $1.47, or 5.6 percent, to $27.52.

DASH OF HOT SAUCE: Spice maker McCormick agreed to buy RB Foods, the food division of Reckitt Benckiser, for $4.2 billion.
