- The Nasdaq Composite was reported at 24,712.60 on November 5, down 3.98% from the previous session's close of 25,736.51.
- Reuters reported that concerns over AI spending and tighter scrutiny of data-center construction drove renewed pressure on chip and infrastructure stocks.
- The index traded more than 10% below its October 6 record close of 27,599.89.
The Nasdaq Composite came under renewed pressure on Thursday, November 5, as investors reassessed the outlook for artificial-intelligence investment and data-center construction. A midday report put the index at 24,712.60, down 3.98% from Wednesday's close of 25,736.51. The calculation uses the reported intraday level and the previous Nasdaq Composite close; the session had not ended at the time of the report.
Reuters reported the level at 12:36 p.m. GMT-3 on November 5, equivalent to 16:36 Berlin time. The move erased the previous session's gains, which had followed the Democrats' sweeping midterm-election victory and lifted the index 1.44% on November 4.
AI infrastructure concerns return
According to Reuters, investors were increasingly focused on whether the election outcome could bring greater scrutiny of further AI infrastructure expansion. The concern is particularly relevant for semiconductor companies and businesses linked to data-center construction, whose valuations have been supported by expectations of rapid spending growth.
The decline also placed the index more than 10% below its record closing high of 27,599.89, reached on October 6. A decline of at least 10% from a recent closing high is widely used as the definition of a correction. The market backdrop therefore shifted sharply from Wednesday's broad rally to a renewed reassessment of the AI investment cycle.
Wednesday's close remains the comparison base
The Nasdaq official index overview lists the November 4 close at 25,736.51 and identifies the instrument as the Nasdaq Composite. Because the U.S. session was still in progress, the reported 24,712.60 should be treated as an intraday level rather than a final close. The next decisive reference will be whether the index can recover before the regular Nasdaq session ends or whether the correction is confirmed on a closing basis.
