Goldman Sachs invests in the second phase of the AI deal to focus on the development of AI infrastructure, including semiconductor companies, cloud service providers, data centers, hardware and equipment manufacturers, security software companies, and utility companies. These companies provide the necessary hardware and service platforms for the development of AI technology. In particular, the report mentions fabs and integrated equipment manufacturers (IDMs), as well as security software companies, as attractive due to their strong expected EPS growth and modest valuations. In addition, utilities may have investment value because analysts and investors have not fully priced their potential AI opportunities.
