The rapid growth of AI companies raises concerns about the sustainability of stock market gains, according to analysts from Freedom24. The American market heavily relies on a few tech giants, impacting Romanian investors holding U.S. stocks or ETFs tracking the S&P 500. Ten AI-related firms, including Nvidia and Microsoft, account for about 40-42% of the U.S. market capitalization, reminiscent of the dot-com bubble. However, current valuations are more moderate than in 2000. The main challenge lies in the profitability of AI investments, with significant infrastructure costs projected. Rising U.S. bond yields could make bonds more appealing compared to stocks, affecting AI companies' funding. Future market performance will depend on tech giants' financial results, Federal Reserve interest rate decisions, and U.S. political context, with potential volatility ahead.
