Chipmakers now trade at a 22% discount to the broader market after the PHLX Semiconductor Index fell 38% over 136 days from its June 22 peak, closing Thursday, November 5, at 9,011.14. The S&P 500 lost only 2% over the same period.
Why it matters
The reversal erases a premium that chip stocks commanded during the AI cycle, when the group traded at about a 15% premium to the market. For investors, it signals that confidence in future AI-related spending is now being tested.
The PHLX Semiconductor Index trades at 13.7 times expected earnings against 17.7 times for the S&P 500, while U.S. cloud providers spend about $1.2 trillion annualized. Whether that spending reaches the $1.55 trillion consensus expected for 2027 has not been established.
The players
Nvidia
Nvidia is a leading designer of graphics processors and AI accelerator chips whose valuation is closely watched as a bellwether for the AI hardware cycle.
The details
Chip stocks declined as investors grew skeptical that hyperscaler capital spending on AI would keep rising. Nvidia's forward price-to-earnings ratio fell to 15.2 times, below that of Kimberly-Clark at 15.5 times. The SOX rose 4.9% on Friday but remains 35% below its June peak.
Timeline
June 22: The SOX peaked at 14,634.72.
Thursday, November 5, 2026: The SOX closed at 9,011.14, down 38% from its peak.
Friday, November 6, 2026: The SOX rose 4.9% in a single session.
Q1 2027: Earnings cuts are expected to begin, which analysts say investors will likely need to see before confidence returns.
Market Dynamics
The shift reverses the valuation premium chipmakers held during the AI cycle, when the group commanded about 15% above the broader market. It now tests whether the earnings that justified that premium will hold as cloud spending plans come under scrutiny.
Investors holding semiconductor funds or chip-heavy index positions face a valuation reset that has already erased much of the sector's premium. The reset may affect retirement accounts and portfolios that gained heavily from the AI rally.
The takeaway
Chip valuations have moved from a premium to a discount, so investors should watch whether upcoming earnings support cloud spending assumptions rather than relying on the AI narrative alone.
What happens next
Analysts expect earnings cuts to begin in Q1 2027, which investors will likely need to see before confidence in chip stocks returns.
