US stock futures were little changed Friday as investors awaited the August payrolls report for indications about labor-market strength and the outlook for monetary policy. In extended trading, DocuSign jumped 4% after reporting better-than-expected second-quarter earnings and revenue and raising its full-year sales guidance. Lululemon Athletica plunged more than 18% after weaker second-quarter sales and profits and a disappointing forecast for the current quarter. The moves followed a broad advance in regular trading Thursday, when the Dow rose 1.18%, the S&P 500 gained 1.06% and the Nasdaq Composite climbed 1.4%, with each benchmark rising for a second straight session. Treasury yields retreated after Federal Reserve Governor Christopher Waller said a rate hike would not be warranted if underlying inflation continues to ease.
