AI Sector Declines 1.61% Amid Broad Market Headwinds – March 28, 2026

The artificial intelligence sector, as measured by the MSGAISNU ETF, registered a decline of 1.61% on Friday, March 28, 2026, as broader market pressures weighed on equities. Technical analysis for the sector gauge indicated a neutral stance despite the daily loss, though specific momentum readings such as the 14-day Relative Strength Index (RSI) were not available.

While no single catalyst was specific to the AI industry, the sector's negative performance occurred within a challenging macroeconomic environment. According to reports from sources including CNBC, surging energy prices, with crude oil surpassing $100 per barrel, created significant headwinds for the broader stock market. This climate of geopolitical uncertainty and inflation concerns likely contributed to the risk-off sentiment affecting technology-related stocks. Sector breadth was decidedly negative, with 37 stocks in the index declining versus only 8 advancers and 1 unchanged name, underscoring the widespread nature of the selling pressure.

Despite the sector-wide downturn, a few companies posted gains. Celestica Inc. (TSE:CLS) rose 2.66%, although no specific fundamental news was identified to explain the move, suggesting it may have been technically driven.

Constellation Energy Corp. (NASDAQ:CEG) advanced 2.13%. The stock's move followed a Reuters report detailing an updated timeline for one of its key projects. A company executive stated that the U.S. grid operator PJM projects a 2031 grid connection for the former Three Mile Island nuclear plant, now the Crane Clean Energy Center. This is four years later than initially planned, but Constellation is reportedly working to accelerate the schedule to meet its goal of supplying power to Microsoft data centers. Volume metrics for the stock were not available.

Western Digital Corp. (NASDAQ:WDC) recorded a modest gain of 0.73%. Similar to Celestica, no direct catalyst was apparent for the session's performance. Volume data was not available at publication.

The AI sector's decline was led by notable losses in several component stocks. Tempus AI Inc. (NASDAQ:TEM) fell 6.39%, a move that occurred despite a positive mention on CNBC's "Lightning Round," where it was called a "decent spec." This suggests that a brief, informal analyst comment was insufficient to overcome broader market selling. Volume data for the stock was not available.

Snowflake Inc. (NYSE:SNOW) experienced a significant drop of 5.87%. No company-specific catalyst was identified for the decline, indicating its performance was likely influenced by broader market trends and technical selling pressure. Volume information for the session was not available.

With a vast majority of its components declining, the AI sector exhibits a cautious tone. Investor focus will likely remain on macroeconomic drivers, including energy prices and geopolitical developments. The selling pressure appears to be sustained over a multi-day period for some names, with notable 5-day declines seen in MongoDB (NASDAQ:MDB) at -13.81%, Tempus AI (NASDAQ:TEM) at -13.27%, and Snowflake (NYSE:SNOW) at -12.28%, highlighting persistent weakness in parts of the sector.

No major macroeconomic data is scheduled for release today.
