Wall Street stocks have recorded eight straight weeks of gains [1], marking the longest winning streak in market history [1].
This rally is significant because it signals a massive shift in investor confidence toward artificial intelligence infrastructure. The current surge is not only benefiting new tech giants but is also reviving legacy companies that dominated the early internet era.
Renewed enthusiasm for former dot-com era computer companies is driving the current rally [2]. Investors have returned to firms such as Cisco, Intel, and Dell, which are seeing a comeback linked to the AI buildout trade [2]. While some of these stocks have reached modest highs, the broader market momentum has left U.S. investors wealthier [1].
However, the rapid ascent has raised concerns regarding market stability. The Shiller P/E ratio, a key metric for valuation, has climbed to levels seen during the dot-com bubble [3]. This metric suggests that the current market may be overvalued, creating a tension between the bullish AI narrative and historical financial warnings [3].
Market analysts are divided on the sustainability of the trend. Some said that former dot-com darlings are catching fire and reaching fresh highs due to AI bullishness [2]. Others said that the Shiller P/E levels serve as a warning of a potential correction [3].
Despite these contradictions, the streak remains intact as of May 2026 [2]. The concentration of gains in computing and AI-related hardware continues to anchor the New York Stock Exchange and Nasdaq [1, 2].
“Eight straight weeks of gains, the longest winning streak in market history”
The convergence of a record-breaking winning streak and valuation metrics mirroring the 2000 crash suggests a high-risk, high-reward environment. While AI provides a tangible catalyst for growth that differs from the speculative frenzy of the late 1990s, the extreme Shiller P/E levels indicate that the market is pricing in near-perfect future growth, leaving little room for error.
