STORY: U.S. stocks ended nearly unchanged in light trading on Friday, with the Dow, S&P 500 and Nasdaq edging nominally lower to snap a five-session rally.Still, all three indexes logged gains for the holiday-shortened week.Just three trading days remain in a turbulent year in which tariff jitters, simmering geopolitical tensions, and the rapid growth of AI-related momentum stocks took investors on a bumpy ride.But it was a year that put the three major indexes, led by the tech-heavy Nasdaq, on track to register double-digit percentage gains.Stocks on the move on Friday included Nvidia, which gained 1% after the AI chipmaker agreed to license chip technology from startup Groq and hire its CEO.Shares of Target rose more than 3% after the Financial Times reported the retailer is facing activism from hedge fund Toms Capital Investment Management, which has made a significant investment in the company.And U.S.-listed shares of precious metal miners such as First Majestic, Coeur Mining and Endeavour Silver advanced as silver and gold prices touched fresh record highs.
