CNBC financial commentator Cramer: Diversification is the key to long-term success, highlighting non-tech stocks such as Johnson & Johnson and 3M.

Golden Finance July 23｜CNBC financial commentator Jim Cramer stated that although Artificial Intelligence (AI) remains an important investment theme driving the US stock market, investors should not overly concentrate their funds in AI concept stocks, especially in the semiconductor sector. He suggests mitigating portfolio volatility through diversification to avoid significant losses caused by a single industry's pullback. Cramer emphasized that he remains optimistic about the long-term prospects of AI and does not oppose technology stock investments, but he has always believed that any single investment theme should not dominate an entire portfolio.

In the healthcare sector, he is optimistic about Johnson & Johnson's continuously expanding innovative pharmaceutical product line. In the industrial sector, he favors 3M, believing that the company is refocusing on innovative research and development and is likely to benefit from diverse industrial demand. In medical services, he highlighted CVS Health, optimistic about its business model that combines chain pharmacies and health insurance. In financial stocks, he is upbeat about Goldman Sachs, Wells Fargo, and Bank of New York Mellon, believing these companies have strong growth potential and, at present, their valuations are still far below many AI-leading enterprises, making their investment appeal comparatively higher.
