NEW YORK — A new agreement between Greece and its creditors helped push U.S. stocks up early Monday. The deal for a new loan package is aimed at keeping the country in the euro.

KEEPING SCORE: The Standard & Poor's 500 index was up 20 points, or 1 percent, to 2,097, as of 11:35 a.m. Eastern time. The Dow Jones industrial average gained 199 points, or 1.1 percent, to 17,960, while the Nasdaq composite climbed 66 points, or 1.3 percent, to 5,064. The gains were broad. More than three stocks rose for every one that fell on the New York Stock Exchange.

A NEW DEAL: European leaders reached a tentative agreement on new loans for Greece, removing an immediate threat that the country would default on its debts and leave the euro. Nine hours after a self-imposed deadline passed, European officials announced the breakthrough early Monday. In exchange for a three-year loan program, the deal requires Greece's parliament to pass tax increases and other key demands from its lenders into law by Wednesday

REACTION: "Our markets have reason to cheer," said Tim Dreiling, senior portfolio manager at the U.S. Bank's Private Client Reserve. "It's a reprieve from worry for a few days at least."

EUROPE: Major markets in Europe rallied on the news. Germany's DAX climbed 1.4 percent and France's CAC 40 surged 2 percent. Britain's FTSE 100 rose 0.7 percent.

NO CABLE, NO PROBLEM: Comcast, the country's largest cable company, announced plans to launch a streaming video service later this summer. The new service, called Stream, will cost $15 a month and allow customers to watch live TV from about a dozen networks, including HBO, on their phones, tablets and laptops. Comcast gained 89 cents, or 1.4 percent, to $64.09.

ASIA'S DAY: Japan's Nikkei 225 gained 1.6 percent, South Korea's Kospi gained 1.5 percent. In China, the Shanghai Composite added 2.4 percent, bouncing back after a slew of government measures to halt a dramatic slide. Hong Kong's Hang Seng rose 1.3 percent.

CRUDE: Benchmark U.S. oil rose 16 cents to $52.90 a barrel on the New York Mercantile Exchange.

BONDS, CURRENCIES: U.S. government bond prices slipped, pushing yields up. The yield on the 10-year Treasury note rose to 2.42 percent from 2.40 percent late Friday. The euro fell to $1.1026 while the dollar rose to 123.37 yen.
