Ciculous Wall Street host, Jim Cramer, has warned investors to consider Nvidia (NVDA) in the current environment and not to rush into the stock. Cramer is not bearish on Nvidia, but cautious, stating that it's the easiest stock in the world to trade due to its liquidity and strong demand. He also mentioned geopolitical tensions as an important factor, particularly noting that the company's products remain mission critical and demand is unlikely to disappear. However, he warned that if the geopolitical situation stabilizes and macro conditions improve, the stock could regain momentum. Despite these concerns, Nvidia's Q4 revenue surged 73% year over year to $68.1 billion.
