Stock market today: Dow, S&P 500, Nasdaq gain as oil, Treasury yields fall

U.S. equities opened higher as Treasury yields and oil prices declined, creating near-term tailwinds for major indices. The Dow, S&P 500, and Nasdaq all gained ground in a market responding to softer fixed-income and energy costs. However, analysts note the rally rests on temporary factors - the underlying fiscal challenges and international economic headwinds remain unresolved, suggesting gains may lack durability.

• Lower yields and oil prices provided immediate support, but structural fiscal and global economic concerns limit upside sustainability.
• Market movements reflect a disconnect between near-term relief and longer-term risk factors still in play.
