According to CoinMeta, recent sell-offs in semiconductor stocks have presented buying opportunities for investors. However, not all semiconductor stocks are worth investing in, and investors should make cautious choices. The stock recommended for purchase is NVIDIA, which holds a leading position in the AI infrastructure sector, has a relatively low current stock price, and continues to grow. NVIDIA's advantage lies in its CUDA software platform, which provides a broad moat for AI model training. Another stock to continue holding is AMD ( AMD ); although its valuation is not as attractive as NVIDIA's, the company has significant growth potential in the AI sector. The stock suggested for sale is Intel ( Intel ); despite strong growth in its AI division, the company lacks competitiveness in the data center market, and its foundry business continues to incur losses.
