Navitas Semiconductor (NASDAQ: NVTS), which trades under the ticker NVTS, recently changed hands near $17 and carried a market value of about $4.3 billion.
NVTS' AI story may be only half the picture as grid upgrades open a $1-$1.8B SiC opportunity tied to rising data center power demand.
NVTS rolls out an isolated SiC MOSFET package to run cooler and switch faster in AI data centers and grid systems, aiming to sharpen its SiC edge.
Navitas stock surged earlier in the week thanks to news that the company's tech was being showcased by Nvidia. The company's share price plummeted in response to rising fears that the Federal Reserve will raise interest rates this year.
Navitas Semiconductor NVTS has become one of the hottest stocks in the semiconductor space.
