Apple, energy shares shine as Wall Street rallies

Wall Street rallied sharply on Monday, juiced by a jump in Apple shares and gains from energy stocks that were backed by stronger oil prices. Apple shares finished up 3.7 percent after Warren Buffett's Berkshire Hathaway reported a stake worth about $1 billion in the iPhone maker. The S&P energy sector gained 1.6 percent as oil prices hit six-month highs.
