Jefferies strategists report that the ongoing artificial intelligence stock rally is sustainable, primarily driven by fundamental earnings growth rather than speculative multiple expansion.
AI-related stocks have accounted for over 80 percent of the S&P 500’s gains so far this year, highlighting a significant market concentration. Excluding the impact of AI stocks, the index would show a modest gain of only 2 percent.
The broker’s analysis suggests the rally's foundation is solid. Because returns are powered by actual corporate earnings, the trend is considered more durable than rallies based on investor sentiment or expanded valuation multiples alone. This provides a more confident outlook for the sector.
The current AI-driven market surge is supported by strong fundamentals. Investors will continue to monitor corporate earnings reports to validate this trend's longevity.
Q: Why does Jefferies consider the AI rally sustainable?
A: Because it is driven by earnings growth, not by an expansion of valuation multiples.
Q: How much have AI stocks contributed to the S&P 500's gains?
A: AI stocks are responsible for over 80 percent of the S&P 500's gains this year.
