Aug 10 (Reuters) - Wall Street was up about 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.
Disappointing data out of China boosted hopes for additional stimulus from Beijing, while Greece and international creditors are close to finalizing a multi-billion euro bailout accord.
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 19.3 percent to $231.25, while Berkshire Class B shares fell 1.4 percent to $141.60.
"The market took their cues from China overnight and the Berkshire deal in another factor driving investor sentiment today," said Aaron Clark, a portfolio manager at GW&K Investment Management, which oversees about $25 billion.

July was the seventh strongest month for global deal activity since 1980. Up to the end of July, cross-border M&A activity totaled $913.5 billion, up 23 percent from a year ago, according to Thomson Reuters data.
"M&A will continue to be robust because funding is still cheap (even with the proposed rate hike) and excess cash needs to be invested. We are also seeing a lot of activist investor activity," said Clark.
At 11:14 a.m. ET (1514 GMT) the Dow Jones industrial average was up 219.93 points, or 1.27 percent, at 17,593.31. The S&P 500 was up 23.16 points, or 1.11 percent, at 2,100.73 and the Nasdaq composite was up 48.47 points, or 0.96 percent, at 5,092.01.
Nine the 10 major S&P sectors were higher, led by the energy index's 2.1 percent hike as oil prices edged up from six-month lows.
The industrials sector rose 1.81 percent, buoyed by Precision Castparts, which also give the third biggest boost to the S&P 500.
In other deal news, ammonia maker CVR Partners said it would acquire Rentech Nitrogen Partners for about $533 million. Rentech soared 26 percent to $12.98.
Mallinckrodt fell 1.1 percent to $99.31 after the drugmaker said it would buy immunotherapy company Therakos in a deal valued at about $1.33 billion.
U.S. stocks ended lower on Friday, with the Dow closing down for the seventh straight day, after solid July jobs data pried the door open a little wider for a potential rate hike in September.
The Fed has said it will raise rates only when it sees a sustained recovery in the economy. Though the labor market has rebounded, inflation rate stays below the 2-percent target.
However, Fed Vice Chairman Stanley Fischer told Bloomberg TV that U.S. inflation is only temporarily "very low" due in part to commodity prices.
Twitter rose 3.9 percent to $28.10 after the National Football League said it will deliver packaged official NFL video and other content daily to Twitter users as part of multi-year strategic partnership.
