Chipmakers, including some with strong ties to India’s tech ecosystem, have posted impressive profit gains, fueling expectations for significant contributions to overall stock market growth. However, recent volatility and mixed investor sentiment challenge the outlook for sustained gains this summer.
- Semiconductor earnings expected to surge 133% year-over-year
- PHLX Semiconductor index up 65% in 2026 but highly volatile in July
- Regulators in South Korea move to reduce volatility from leveraged ETFs
What happened
Semiconductor companies within the S&P 500 are projected to deliver a remarkable 133% increase in earnings for the second quarter compared to last year, contributing nearly half of the overall S&P 500 profit growth. This surge is primarily driven by strong demand in AI, data centers, industrial electronics, and wireless communications.
Despite these strong earnings reports, chipmaker shares have experienced notable price volatility, with the PHLX Semiconductor index jumping 65% year-to-date but falling 18% in July amid swings of 3 percentage points or more on multiple trading days. Even leading firms such as Taiwan Semiconductor Manufacturing and Samsung Electronics saw share prices decline after reporting strong profits.
Why it matters
The semiconductor sector’s outsized profit gains are critical for the broader stock market given their large weight in the S&P 500. However, the current market turbulence raises concerns about the sustainability of chip demand, especially related to the artificial intelligence boom, which some investors fear may be overheated or short-lived.
The sector’s volatility has been amplified by retail investor activity and leveraged exchange-traded funds (ETFs), which magnify price movements. This increased volatility has drawn regulatory attention, exemplified by South Korea’s recent measures to curb market swings caused by ETFs linked to chipmakers like Samsung and SK Hynix.
What to watch next
Upcoming earnings reports from major US chipmakers such as Intel and Texas Instruments will be closely monitored for signs of sustained demand or potential cracks in outlooks. Nvidia’s results, expected later, will also be critical given its leading role in AI chip markets.
Investors will be watching broader economic conditions alongside the semiconductor sector’s earnings to assess if the summer selloff continues or reverses. The market’s reaction to any disappointing earnings guidance may determine whether chip stocks—and by extension the S&P 500—face further turbulence.
