The chipmaker's decline was worse at the closing bell than it looked at midday, while Apple gained the same session. Neither move has a company-specific explanation on record.
Nvidia shares did not recover into Friday's close. They weakened further.
The stock finished the regular session at $217.55, down 4.57 percent, or $10.43, from the prior close of $227.98. That decline was steeper than the roughly 4 percent drop visible at midday. Nvidia traded as low as $216.82 and as high as $229.26, leaving the closing price near the bottom of the day's range rather than reflecting an intraday dip that reversed by the bell.
Apple moved the opposite direction. Shares closed at $319.70, up 1.63 percent, or $5.12, from the previous session. By Friday's close, Nvidia's market capitalization stood at roughly $5.269 trillion against Apple's $4.696 trillion, a gap of about $573 billion. Before Nvidia's post-earnings weakness, that gap had been closer to $492 billion.
No company-specific catalyst was identified for either Friday move in the source material. Nvidia's decline instead fits a broader pattern visible across AI-linked chip and infrastructure names, including weakness in Marvell during the same session. Friday also followed a hawkish shift in Federal Reserve expectations after Kevin Warsh's Jackson Hole remarks, a backdrop that weighed on rate-sensitive growth stocks more broadly. That macro explanation is plausible, but the available evidence does not establish it as the sole driver of Nvidia's move.
Apple's gain is similarly difficult to isolate. It could reflect ordinary single-session noise or a relative preference for Apple while semiconductor and AI-infrastructure names were under pressure. There is not enough evidence to assign a definitive cause.
The cleaner conclusion is in the tape itself: Nvidia's post-earnings weakness intensified into Friday's close while Apple gained, widening the valuation gap between the two companies. The next regular session will show whether that divergence persists or simply marked the end of a volatile week.
