Stock futures were slightly higher Wednesday after Wall Street's losing streak stretched into its third day and endangered the market's recent summer rebound. Futures tied to the Dow Jones Industrial Average gained 25 points, or 0.1%. S&P 500 futures advanced 0.3%. Nasdaq 100 futures outperformed, advancing 0.7%. Shares of Chewy tumbled more than 11% in the premarket after the pet products retailer issued weak revenue guidance. HP Inc's stock dipped 6% after the company missed revenue estimates. Investors have sold off heavily since Friday after hawkish remarks from Federal Reserve Chair Jerome Powell. Most recently, New York Fed President John Williams called for "somewhat restrictive policy to slow demand." The sell-off on Wall Street rolled into Tuesday, with the Dow Jones Industrial Average sliding nearly 1%. The Nasdaq Composite dropped 1.1%, and the S&P 500 slumped 1.1%, falling below the 4,000 mark for the first time since late July. All the major averages were on pace to finish August with losses. Despite Tuesday's sell-off and hawkish Fed remarks, some investors are hopeful that the rate hiking cycle could be nearing its end. "We think we're close to the end of this rate-hiking cycle, but it certainly depends on a lot of things," Brenda Vingiello, chief investment officer of Sand Hill Global Advisors said on CNBC's "Closing Bell: Overtime" on Tuesday. "No doubt the Fed's gonna raise rates in September, and likely two more times this year, but they will have at that point done a lot and we will be in restrictive territory." Ahead of Friday's closely watched August jobs data, more Fed speeches are slated for Wednesday. Chicago PMI and ADP employment data are also due out in the morning. Wednesday's also the last trading day of the month. The Dow and S&P 500 are both down more than 3% in August, while the Nasdaq has lost 4% in that time.
