Stock Market Update

[BRIEFING.COM] The S&P 500 (+0.1%) and Nasdaq Composite (+0.3%) flirted with last Friday's record high levels amid an early rally in chipmakers, though mixed sector strength has the indices off their opening highs, sending the DJIA (-0.5%) into negative territory.

Advanced Micro Devices (AMD 208.80, +44.13, +26.80%) and OpenAI's announced partnership sent the stock soaring, underpinning a 3.9% gain in the PHLX Semiconductor Index. 

Micron (MU 199.85, +12.02, +6.40%) also contributes to the rally after being upgraded to Overweight from Equal Weight at Morgan Stanley. 

Meanwhile, competitor NVIDIA's (NVDA 185.34, -2.28, -1.22%) stock has moved lower, limiting gains in the broader information technology sector (+0.7%). 

After retreating on Friday, the technology sector is among the best-performing of the four advancing S&P 500 sectors this morning.
