Nvidia's ($NVDA) recent financial performance has sparked comparisons with Cisco during the Dot Com Bubble. However, analysts argue that these comparisons are flawed due to Nvidia's parabolic earnings growth, which contrasts with Cisco's performance during that period. Despite Nvidia's impressive earnings, concerns have arisen about the company's future prospects as gross margins narrow, potentially leading to a decline in earnings and revenue. Analysts still expect Nvidia to achieve over $200 billion in revenue by FY 2027. The stock price may react to these warnings.
