Market Summary — Midday — 2026-09-19

Market Summary

U.S. equities closed out a volatile week on a mixed note Friday, with the S&P 500 (7650.50, +12.74, +0.17%) and Nasdaq Composite (26543.59, +104.25, +0.39%) staging an afternoon recovery while the DJIA (51682.64, -95.40, -0.18%) slipped into the red. The rebound followed a weak first half of the session in which rising Treasury yields and broad-based selling pushed the major averages to their lows, driven largely by renewed strength in semiconductors and select mega-cap growth names rather than a broad advance. Only three of eleven S&P 500 sectors finished higher on the day, and small- and mid-cap stocks continued to lag, with the Russell 2000 down roughly 0.5% and the S&P Mid Cap 400 off about 0.3%.

The PHLX Semiconductor Index surged 2.8% on the session, powering Information Technology to the top of the sector leaderboard behind standout gains in Sandisk (SNDK) and Seagate Technology (STX) amid continued AI data-center demand narratives. Financials found support from a crypto-driven rally in Coinbase (COIN) and Robinhood (HOOD) following the SEC’s new “Innovation Exemption” for tokenized equities and Bitcoin’s push above $81,000. Meanwhile, rate-sensitive groups—Utilities, Real Estate, and Materials—remained under pressure as the 10-year Treasury yield climbed to 5.00%, and Communication Services lagged behind a sharp Netflix (NFLX) decline tied to a Wells Fargo downgrade.

For the week, the Nasdaq Composite was the only major average to finish higher (+0.7%), while the S&P 500 (-0.1%), DJIA (-1.7%), and Russell 2000 (-1.5%) all posted losses as the Fed’s rate hike and persistently elevated yields weighed on the broader market beneath a narrow layer of mega-cap and semiconductor leadership.

Stock Spotlight

Nucor (NUE) & Steel Dynamics (STLD) were among the session’s most notable laggards after both domestic steelmakers guided Q3 EPS below Street expectations — a surprising development given that Q3 is typically a seasonally strong period for steel shipments. Nucor guided to Q3 EPS of $5.55-$5.65, citing anticipated earnings growth in its steel mills and steel products segments offset by weakness in raw materials and higher corporate/eliminations expense. Steel Dynamics guided to $5.34-$5.38, with higher average realized steel selling values and lower scrap costs cited as supportive factors. Shares fell 6.32% and 4.11%, respectively.

Despite the headline miss, the underlying commentary was more constructive than the guidance alone suggests. Both companies pointed to higher steel selling prices, and STLD specifically flagged lower scrap costs and persistently low customer inventories supporting continued order strength. With a 50% U.S. tariff on steel imports limiting import competition and end-market demand holding up across construction, energy, automotive, and industrial sectors, the domestic steel pricing backdrop remains structurally supportive even as near-term earnings visibility took a hit.

Bond Market & Treasuries

Treasuries sold off broadly into the close, locking in weekly losses for the 10-year note and shorter tenors while the long bond outperformed for the week.

• 2-yr: 4.74%, +5 bps on the day (+10 bps week-to-date)
• 3-yr: 4.83%, +7 bps (+10 bps WTD)
• 5-yr: 4.86%, +6 bps (+7 bps WTD)
• 10-yr: 5.00%, +5 bps (+2 bps WTD)
• 30-yr: 5.33%, +4 bps (-3 bps WTD)

The 2s10s spread tightened 8 bps to 26 bps. Key drivers included the Bank of Japan’s 25-bp rate hike to 1.25% (a 7-2 vote) that failed to strike a hawkish tone and pressured the yen, an overnight rise in crude prices, and comments from Fed Governor Bowman on the SVB failure review and potential stress-test revisions. Separately, reports indicated the U.S. will delay tariffs on excess manufacturing capacity until after China President Xi’s visit. The U.S. Dollar Index touched a seven-week high before settling near 100.25, up 1.1% for the week.

Commodities

• WTI Crude: $100.24/bbl, -1.8% — nearly flat for the week
• Gold: $4,425.30/ozt, +0.6%
• Copper: $6.69/lb, +0.5%
• Silver: Not reported in available data

Overseas Markets

• Bank of Japan: Raised its policy rate 25 bps to 1.25% as expected, but a 7-2 vote and Governor Ueda’s lack of hawkish tone weighed on the yen; USD/JPY rose 0.5% to 156.68
• Japan: August National CPI +0.1% m/m, +1.9% yr/yr; Core CPI +1.7% (vs. 1.8% expected)
• South Korea: August PPI +0.2% m/m, +7.9% yr/yr
• New Zealand: August FPI +0.3% m/m; trade deficit of NZD1.35 bln (narrower than expected NZD1.775 bln deficit)
• Eurozone: July current account surplus of EUR27.6 bln (below expected EUR30.7 bln); July construction output unchanged m/m
• U.K.: August retail sales +0.5% m/m (vs. -0.2% expected), +2.4% yr/yr; core retail sales +0.6% m/m, +2.7% yr/yr — notable upside surprise
• Germany: August PPI +1.1% m/m (vs. 0.6% expected), +4.6% yr/yr
• Currencies: EUR/USD +0.1% to 1.1485; GBP/USD +0.3% to 1.3394; USD/CNH -0.1% to 6.6949

Economic Data

• Industrial Production (Aug): Unchanged m/m (consensus +0.3%) following an unrevised +0.2% in July; total IP +1.4% yr/yr. Softness attributed to a manufacturing output decline following seven straight months of gains.
• Capacity Utilization (Aug): 76.3% (consensus 76.4%), unchanged from July, 3.1 percentage points below its long-run average.
• Leading Economic Index (Aug): -0.1% (consensus +0.2%) after a +0.2% July reading — a modestly negative signal on forward growth momentum.

Looking Ahead

Week Ahead:

• Monday: Nothing of note scheduled
• Tuesday: $69 billion 2-year Treasury note auction results at 13:00 ET
• Wednesday: Weekly MBA Mortgage Index (prior -4.1%) at 7:00 ET; flash September S&P Global U.S. Manufacturing PMI (prior 53.9) and Services PMI (prior 56.5) at 9:45 ET; weekly crude oil inventories (data cut off)

Markets will continue to monitor the path of Treasury yields near 2026 highs, follow-through in semiconductor and AI-infrastructure leadership, and any fresh commentary from Fed officials following last week’s hawkish 25-bp rate hike.
