Aug 10 (Reuters) - Wall Street was up more than 1 percent on Monday, bouncing back sharply from last week's steep lows, buoyed by optimism around China and Greece, and as Warren Buffett's latest billion-dollar deal showed the M&A boom was alive and well.

Buffett's Berkshire Hathaway said it would buy Precision Castparts in a deal valuing the company at $32.3 billion. Precision Castparts' shares jumped as much as 19.4 percent to $231.47, while Berkshire Class B shares fell 1.4 percent to $141.60.
"The market took their cues from China overnight, and the Berkshire deal is another factor driving investor sentiment today," said Aaron Clark, a portfolio manager at GW&K Investment Management, which oversees about $25 billion.
