Today, the Dow Jones Industrial Average (INDEX: ^DJI) moved 1.5% on a higher growth projection from the International Monetary Fund, a strong bond sale by Spain, and some positive earnings news. In fact, not one Dow component fell today. Here's a look at some of the biggest winners during the trading session.

The movie maker
Unlike its John Carter movie, Disney (NYSE: DIS) put forth a spectacular day, climbing 2.45%, higher than all of its Dow peers. Helping Disney through its box-office failure is a diverse product line. As fellow Fool Eric Volkman describes, "out of its five divisions, no single one is responsible for more than 50% of revenue." Eric also notes that its musical version of The Lion King recently became the top-grossing show of all-time on Broadway.

The snack maker
Standard & Poor's analysts gave Kraft's (NYSE: KFT) stock a "buy" rating, and shares jumped 2.39% following the news. The analyst "expects a valuation boost," according to the Associated Press, because of its coming split into a North American grocery division and a global snack-foods division named Mondelez. Currently, Kraft is the second largest food company in the world, and it wants to separate out the high-growth international potential from its mature North American business. It plans to report first-quarter earnings on May 3.

The soda maker
Coca-Cola (NYSE: KO) released its first-quarter results and beat analysts' expectations on both earnings and revenue, posting $0.89 in earnings per share and $11.14 billion in revenue, which sent shares 2.08% higher. Total global volume increased 5%, pushed by an amazing volume growth of 20% in India and 9% in China. As Fool James Early noted, with its increased volume and increased prices, Coke proved that it can pass on higher commodity prices.
