Nvidia, Micron and Dollar Tree All Rise Today

Today's biggest winners and losers in the stock market.

On this episode of Stock Movers:
- Nvidia Corp. expects to generate at least $1 trillion from its Blackwell and Rubin chips through the end of 2027. The company unveiled new products at its GTC event, including a chip made with technology acquired from startup Groq, and a computer made up of general-purpose CPUs. Nvidia's CEO Jensen Huang said the CPU opportunity is "for sure" a multibillion-dollar business, as the company expands into technology pioneered by Intel Corp.

- Micron Technology was the S&P 500's best performer ahead of the opening bell, rising 4.7%. The memory-chip maker said it plans to build a second manufacturing facility at its site in Taiwan by the end of 2026. 

- Dollar Tree shares rise as much as 5.7%, the most intraday since Dec. 5, after the retailer’s conference call comments eased investors concerns about the traffic decline in in the fourth quarter, as transaction size drove comparable sales growth.
