U.S. stock index futures opened mixed on Friday as markets continued to process the Federal Reserve's first interest rate hike in three years and tracked a further decline in oil prices. Nasdaq-100 futures rose approximately 0.3 percent, S&P 500 futures were little changed to slightly higher, and Dow Jones Industrial Average futures edged lower by about 0.1 percent in early trading. The setup followed a strong rebound on Thursday in which the Nasdaq Composite advanced 1.7 percent, the S&P 500 gained 1.1 percent, and the Dow rose 0.6 percent, reversing much of the prior session's post-decision losses.

On Wednesday the Federal Open Market Committee voted unanimously to raise the target range for the federal funds rate by 25 basis points to 3.75 to 4.00 percent, citing still-elevated inflation and signaling that at least one additional increase could be appropriate this year. Updated projections showed most officials expecting further tightening before year-end. Fed funds futures on Thursday evening priced roughly even odds of another quarter-point move at the late-October meeting, which falls just before the U.S. midterm elections. The 10-year Treasury yield firmed modestly on Friday, trading near 4.95 to 4.97 percent after having declined the previous day.

Technology and semiconductor stocks provided the primary leadership in premarket activity, extending the recovery that began Thursday after earlier-week concerns about a potential slowdown in artificial-intelligence development had weighed on the group. Chipmakers including several large-cap names had posted strong gains in the prior session, helping the PHLX Semiconductor Index reclaim a substantial portion of its weekly losses. The decline in crude oil prices for a third consecutive day, with West Texas Intermediate hovering near $100 to $101 per barrel, offered a partial offset to inflation worries that had intensified around the Fed decision.

Economic data on Friday's calendar included the August industrial production and capacity utilization reports. Asian equity markets closed mostly higher, with South Korea's Kospi rising approximately 2.7 percent on strength in chip-related shares, while European stocks traded lower as economically sensitive sectors underperformed. The mixed U.S. futures tone reflected ongoing uncertainty about the ultimate path of interest rates and the sustainability of the post-hike equity rebound. Breadth on Thursday had been constructive, with a majority of stocks advancing, yet the Russell 2000 lagged the large-cap indexes, highlighting continued preference for mega-cap technology exposure.

Investors remain focused on upcoming comments from Federal Reserve officials for additional clues about the timing and magnitude of further policy tightening. The combination of still-elevated energy prices, sticky core inflation readings, and a resilient labor market has kept the door open to additional hikes even as growth remains solid. Equity market leadership continues to hinge on the technology sector's ability to maintain momentum, given its outsized weighting in the major indexes. A durable stabilization in Treasury yields and further moderation in oil prices would likely be viewed as supportive for risk assets in the near term.

For the week as a whole, the Nasdaq was positioned to finish higher while the Dow and S&P 500 remained on track for modest declines heading into the final session. Options expiration dynamics and end-of-week positioning added another layer of potential volatility. Market participants will parse the industrial production data and any Fed speaker remarks for incremental signals, but the dominant narrative remains the digestion of the first rate increase in three years and the implications for equity valuations under a higher-for-longer policy stance.
