Tuesday morning began with a truly peculiar moment in the history of the market. In the first hour of trading, the Nasdaq Composite briefly reached a new 52-week high of 24,537, which on any other Tuesday would have been cause for celebration. Oil reversed upward past $90, the geopolitical news cycle reasserted itself, reports emerged that Vice President Vance’s trip to Pakistan for Iran negotiations had been postponed, and the index declined for the remainder of the session. The Nasdaq was down about 0.6 percent by the end of the day. It ended the day lower after setting a record in the morning. That kind of whipsaw is typical for a market navigating a real-time geopolitical situation, but it does reflect the current state of investor psychology, which is both cautious enough to sell as soon as the news changes and optimistic enough to push toward highs.
The backdrop for Tuesday’s reversal is a run that has been exceptional by nearly all historical standards. On Monday, the Nasdaq ended a thirteen-day winning run, the longest since 1992 and only the fourth of its kind in the index’s recent history. The Nasdaq increased in value by hundreds of billions during those thirteen sessions, with the majority of the movement coming from technology and artificial intelligence stocks. For the first time, the S&P 500 exceeded 7,100. From 15,685 at the low to 24,537 intraday Tuesday, the Nasdaq’s 52-week range represents a gain of about 56% from trough to peak in roughly a year. It is difficult to pinpoint a single explanation for that kind of movement in a year that also saw a war between the United States and Iran, rising oil prices, and ongoing Federal Reserve uncertainty.

The Nasdaq’s recent performance clearly demonstrates the impact of AI. Based on available data, 66% of S&P 500 AI-related stocks have outperformed the overall market since early April. After significantly declining in late February and early March, Nvidia has risen more than 22% from its most recent low. Over a comparable time frame, Alphabet, Amazon, and Meta have all increased by more than 20%. The advent of Anthropic’s Claude Mythos model, a sophisticated AI system that JPMorgan specifically cited in its April 21st S&P 500 target upgrade, rekindled enthusiasm that had subsided during the market turbulence caused by the war. Given how strongly its composition favors the tech firms developing and implementing these systems, the Nasdaq is the index that depends more on the AI story than the Dow or even the S&P 500.
But when you look at the bigger picture, there is something worthwhile. 15,685 was the Nasdaq’s 52-week low. The intraday high for today was 24,537. This disparity—nearly 9,000 points in a year—occurred at the same time that consumer sentiment hit its lowest point ever. In the midst of an ongoing conflict, oil prices spiked above $90. There was genuine doubt about the outcome of a Federal Reserve chair nomination hearing that was taking place on Capitol Hill. Even those who understand intellectually that financial markets price future expectations rather than current conditions find it unsettling to see the divergence between the index and the general state of the economy. It is genuinely unclear if the market is simply outpacing itself on AI optimism and war-resolution hopes, or if those future expectations are well-calibrated.
What transpires on Wednesday is very important. The trajectory of the Nasdaq over the next few sessions will reveal a lot about whether the recent record-breaking levels reflect enduring conviction or something more brittle as the U.S.-Iran ceasefire is about to expire. Very little of the thirteen-day run was recovered in Tuesday’s session, which is actually encouraging. The index is still near its highest point ever. The earnings calendar is packed; on April 30, Microsoft will release data that will directly assess whether investments in AI are generating income. As the Nasdaq navigates all of this over the next two weeks, there’s a sense that this is one of those times when the result actually matters and the market’s response will be something to watch.
