"Warning: Key Red Flag to Consider Before Investing in Nvidia at $800"

Nvidia's stock has surged to over $800, reflecting its dominant position in the AI chip market, but investors should be cautious due to the company's heavy reliance on a small group of tech giants for a significant portion of its revenue. There is a potential risk of these companies developing their own AI chips, which could impact Nvidia's future business. While the long-term demand for AI chips remains strong, investors should carefully consider the stock's lofty expectations and the potential for increased competition in the market before investing.
