• The S&P 500 notched a new record on Thursday amid encouraging labor-market data and China stimulus.

US stocks climbed on Thursday amid positive economic data and promises from China to roll out further stimulus measures. The S&P 500 notched a fresh record.

A surge in Micron's stock led the gain, fueled by a better-than-expected earnings report and guidance. The memory chipmaker was up as much as 20% at intraday highs, and closed 15% higher.

Thursday's gains were also fueled by a pledge from Beijing to support China's economy with further stimulus measures, just days after the country unveiled a blitz of policies to reinvigorate its sluggish economy and real-estate market.

Meanwhile, new jobless-claims data fell unexpectedly, offering a sign of stability for the labor market and fueling further bets for aggressive rate cuts.

Heading into Friday, traders are eagerly awaiting personal consumption expenditure data, due Friday.
