Market Summary
On June 23, 2026, U.S. equities finished lower as a pronounced momentum unwind in the semiconductor sector and mega-cap technology stocks dragged down the major averages, masking a resilient performance in the broader market. The Nasdaq Composite led the decline, falling 2.21% to 25,608.03, while the S&P 500 dropped 1.44% to 7,365.46. The Dow Jones Industrial Average proved the most resilient, ending the session nearly flat with a negligible loss of 0.09% at 51,666.84. This divergence was highlighted by the S&P 500 Equal Weight Index, which finished with a significantly narrower loss (-0.4%) compared to its market-cap weighted counterpart, underscoring that today’s weakness was highly concentrated in specific growth names rather than a broad-based sell-off.
The primary driver of the session was a 7.9% collapse in the PHLX Semiconductor Index, triggered by a 10% plunge in South Korea’s Kospi and regulatory concerns regarding leveraged ETFs tied to SK Hynix and Samsung. This overseas weakness spilled over into U.S. chipmakers, with memory stocks taking the hardest hit ahead of Micron’s upcoming earnings. Despite the heavy losses in technology, defensive rotation provided a floor for the market. Six S&P 500 sectors finished in positive territory, led by Consumer Staples and Health Care, while the CBOE Volatility Index (VIX) surged 12.4% to 19.43, reflecting heightened investor anxiety regarding the AI trade valuation.

Stock Spotlight
Primoris Services (PRIM)
Primoris Services faced a severe sell-off, dropping approximately 26% after slashing its FY26 adjusted EPS guidance to $2.05–$2.60 from a previous range of $4.80–$5.00. The guidance cut was driven by significant cost overruns and project delays within its Renewables segment, specifically affecting six projects. Consequently, the company now expects FY26 revenue for Renewables to decline to $2.1 billion from $3 billion in 2025. Compounding the negative sentiment, COO Jeremy Kinch stepped down from his role. While the company did announce new Energy segment projects worth ~$2 billion, the magnitude of the guidance reduction—cutting EPS estimates by more than half in less than two months—signals deep execution issues rather than isolated hiccups. This follows a pattern of leadership turnover and raises concerns about management’s visibility into the renewables backlog.
Bond Market & Treasuries
U.S. Treasuries recorded modest gains, with yields moving lower as investors sought safety amid the equity sell-off, though intraday action was largely sideways.
* 2-Year Note Yield: Settled at 4.19% (-4 bps).
* 10-Year Note Yield: Settled at 4.49% (-2 bps).
* 30-Year Note Yield: Settled at 4.94% (-1 bp).
* Auction Results: The Treasury sold $69 billion in 2-year notes to solid demand. The high yield stopped through at 4.189%, with a bid-to-cover ratio of 2.64x.
* Drivers: The flight to quality was supported by the “momentum unwind” in tech and concerns over AI ROI. The front end of the curve saw a pullback late in the session despite strong auction demand.
Commodities
* Crude Oil (WTI): $73.28/bbl (-2.5%). Dipped below its 200-day moving average ($73.90).
* Gold: $4,148.90/ozt (-1.3%).
* Silver: $65.54/oz (-0.73%).
* Copper: $6.15/lb (-3.5%).
* Natural Gas: $3.25 (+0.01).

* South Korea (Kospi): -10.0%. Plunged due to losses in SK Hynix and Samsung Electronics, exacerbated by regulatory concerns over leveraged ETFs.
