The major averages finished lower today, with the S&P 500 (-0.5%), Nasdaq Composite (-1.5%), and DJIA (-0.2%) retreating as another bout of weakness across semiconductor stocks, coupled with late selling in several other mega-cap technology names, outweighed continued rotational strength elsewhere in the market. While underlying participation remained relatively constructive, concentrated weakness across growth-oriented stocks ultimately dictated the direction of the major averages.

Semiconductor stocks remained the primary source of weakness throughout the session, with the PHLX Semiconductor Index falling 4.3%. Today's selling followed another double-digit overnight decline in SK hynix Inc.'s (SKHY 152.31, -24.15, -13.69%) Korean-listed shares, while Taiwan Semiconductor Manufacturing (TSM 410.06, -9.42, -2.25%) faced sell-the-news pressure despite delivering a beat-and-raise earnings report.

Memory stocks again bore the brunt of the weakness, with Sandisk (SNDK 1411.08, -203.92, -12.63%) and Seagate Tech (STX 745.49, -82.81, -10.00%) ranking among the worst-performing S&P 500 components.

Apple (AAPL 333.26, +5.76, +1.76%) and Microsoft (MSFT 401.10, +5.47, +1.38%) posted solid gains that helped cushion some of the pressure on the information technology sector (-1.8%), though they were not enough to offset the broader weakness across chipmakers.

Selling broadened across other mega-cap growth stocks as the afternoon progressed. The communication services sector (-3.0%) finished as the worst-performing S&P 500 sector after Alphabet (GOOG 353.81, -16.40, -4.43%) moved sharply lower on a Bloomberg report that the launch of its Gemini 3.5 Pro model has been delayed after missing internal performance targets. Meta Platforms (META 664.54, -16.77, -2.46%) also finished lower, while Netflix (NFLX 74.35, +0.67, +0.91%)edged higher ahead of its earnings report after the close.

Amazon (AMZN 249.89, -5.07, -1.99%) added to the weakness in the consumer discretionary sector (-0.3%), and the Vanguard Mega Cap Growth ETF fell 1.4%.

Even so, underlying participation remained stronger than the major averages suggested. The consumer staples sector (+2.9%) finished with the widest gain as broad-based strength, including solid advances in Coca-Cola (KO 84.92, +2.47, +3.00%) and Walmart (WMT 114.95, +2.42, +2.15%), helped cushion losses in the DJIA.

The health care sector (+2.2%) was another standout, supported by strong post-earnings gains in UnitedHealth (UNH 423.38, +4.86, +1.16%) and Abbott Labs (ABT 98.82, +9.55, +10.70%).

The real estate sector (+2.1%) also outperformed, while the S&P 500 Equal Weight Index (+0.9%) substantially outpaced the market-weighted S&P 500 (-0.5%).

The industrials sector finished little changed after a mixed slate of earnings reactions. GE Aerospace (GE 345.73, -14.62, -4.06%) traded lower despite delivering a beat-and-raise earnings report, while United Airlines (UAL 118.84, -2.13, -1.76%)declined after third-quarter guidance came in just below consensus despite a second-quarter earnings beat. Offsetting some of that weakness, J.B. Hunt Transport (JBHT 298.41, +22.13, +8.01%) rallied to a fresh record high after delivering a sizable earnings beat and offering encouraging commentary on its earnings call.

Meanwhile, the energy sector (+1.0%) extended this week's relative outperformance even as crude oil settled modestly lower following a comparatively quiet day of geopolitical headlines surrounding the U.S. and Iran.

Outside the S&P 500, the Russell 2000 (-0.3%) gave back its earlier gains, while the S&P Mid Cap 400 (+0.4%) managed to finish modestly higher.

Although today's session initially featured encouraging rotational strength outside of technology, renewed weakness across semiconductor stocks and late selling in several other mega-cap growth names ultimately overwhelmed that trend. Defensive sectors and the equal-weighted S&P 500 continued to demonstrate healthy underlying participation, but persistent pressure on the market's largest growth stocks remained the dominant influence on index-level performance.

U.S. Treasuries had a soft overnight session that was driven by selling across the curve that was mirrored by losses in other sovereign bond markets. The losses for the Treasury market dissipated as the cash session progressed, aided by a faltering stock market, a retreat in oil prices despite more saber rattling by Iran, and some technical resistance as the 10-yr note yield challenged the 4.60% level. The 2-year note yield settled up three basis points to 4.16%, and the 10-year note yield settled up two basis points to 4.57%.
