US stocks mixed at open: Nasdaq climbs 0.4%, Dow trades flat

Reasoning: The piece describes mixed intraday action — modest S&P gains and Nasdaq outperformance driven by a few tech names and a metals rebound — but also notes ongoing volatility and a heavy, potentially noisy earnings calendar, so there is no clear broad directional bias.

Reasoning: Despite a mixed open, the Nasdaq outperformed with a 0.4% climb driven by tech gains, the S&P 500 was modestly higher, and a significant rebound in precious metals signaled a stabilization of risk appetite after a period of selling.
