Nvidia's AI prospects expand beyond GPUs

Nvidia has been a top-performing stock in the AI era, with a $1,000 investment now worth over $5,400. The company's growth continues to accelerate, but its stock returns have been lukewarm this year. Nvidia is expanding its AI presence through investments in other companies, including Lumentum Holdings and Coherent. The company has a $2 billion stake in Coherent to support its manufacturing capabilities. Nvidia's investments make it a bigger AI play than the market realizes.
