Nvidia could be worth $6 trillion if it follows Cisco's dot-com trajectory, says Jeremy Siegel

• Nvidia stock could triple if it follows Cisco's path during the dot-com bubble, Jeremy Siegel said.
• The chipmaker could be worth more than $6 trillion and blow away Apple and Microsoft,  he said.
• The Wharton finance professor said speculation is less extreme now than during the internet boom.

Nvidia could triple in value to become the world's first $6 trillion-plus company if it follows Cisco's trajectory during the dot-com bubble, Jeremy Siegel said.

The microchip maker's stock has surged by more than 500% since the start of 2023, including a near-90% jump in the past 10 weeks alone.
