NEW YORK (AP) -- Stocks rose in afternoon trading Monday, led by gains in energy companies as the price of crude oil increased sharply. Marathon Oil jumped 6 percent and offshore driller Transocean rose 4.5 percent. Major U.S. stock indexes have fallen for three weeks in a row.
KEEPING SCORE: The Dow Jones industrial average rose 170 points, or 1 percent, to 17,704 at 1:03 p.m. Eastern time. The Standard & Poor's 500 index rose 19 points, or 0.9 percent, to 2,065. The Nasdaq composite gained 55 points, or 1.2 percent, to 4,773.
OIL JUMP: Benchmark U.S. crude rose $1.49, or 3.2 percent, to $47.70 a barrel following news of continued production troubles in Nigeria and an upbeat forecast from Goldman Sachs. Analysts at the investment bank said the crude market has gone from oversupply to a "deficit" much earlier than it had expected. They expect the U.S. crude to rise to about $50 a barrel in the second half of this year. Brent crude, which is used to price international oils, added $1.27 to $49.10 per barrel in London.
THE QUOTE: "If it's oil making headline news, stocks will trade off of oil," said Anna Rathbun, director of research for investment manager CBIZ Retirement Plan Services. She said she is skeptical there will be any "long-term rally" in stocks because companies are struggling to increase earnings.
BUFFETT BUYS APPLE: Warren Buffett's Berkshire Hathaway bought 9.8 million Apple shares in the first quarter, a stake now worth nearly $1 billion, as the tech giant traded near its lowest price in almost two years, according to regulatory documents released Monday.

ENERGY BOOST: Memorial Resource Development rose 75 cents, or nearly 6 percent, to $14.20 per share after natural gas company Range Resources said it would buy it for $3.3 billion. Range Resources plunged $3.38, or 8 percent, to $38.63.
DRUG DEAL: Anacor Pharmaceuticals rocketed 55 percent to $99.44, a gain of $35.43, after drug giant Pfizer announced a deal to buy the maker of eczema treatment for $5.2 billion. Pfizer was mostly unchanged at $33.27.
PAPER CHASE: Tribune Publishing soared $2.59, or 22 percent, to $14.06 after USA Today owner Gannett raised its offer to buy the rival newspaper publisher. Gannett increased its bid to $15 per Tribune share, up from $12.25. Gannett rose nearly 2 percent.

CHINESE WEAKNESS: A report over the weekend showed that industrial production growth in China slipped to a year-on-year rate of 6 percent in April from 6.8 percent the previous month, adding to fears of a slowdown in the world's second-biggest economy.
ANALYST TAKE: The report "paints an altogether gloomier picture," said David Cheetham, market analyst at XTB. He said the report is worrisome given that China "poured a record amount of fresh credit into the economy for the first quarter."
