Indexes surge 1 percent led by Apple, energy shares

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 were up 3.9 percent after Warren Buffett's Berkshire Hathaway reported a stake worth about $1 billion in the iPhone maker. The S&P energy sector was the best-performing group as oil prices hit six-month highs.
