US stocks touched their highest levels in two weeks as a flurry of deal activity and strong quarterly earnings boosted investor confidence.

"M&A activity is generally seen as a bullish trend for the market," said Randy Frederick, managing director of trading and derivatives for Charles Schwab in Austin, Texas.
