Market Summary
U.S. equities closed out a volatile week on a mixed but ultimately constructive 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 from session lows, while the DJIA (51682.64, -95.40, -0.18%) slipped modestly. The rebound was narrow rather than broad-based — only three of eleven S&P 500 sectors finished in positive territory — as semiconductor strength and mega-cap leadership offset renewed pressure from rising Treasury yields. The PHLX Semiconductor Index surged 2.8% on the session, providing the clearest source of support, while the Vanguard Mega Cap Growth ETF added 0.4%.
Small- and mid-cap stocks continued to lag badly, with the Russell 2000 down 0.5% and the S&P Mid Cap 400 off 0.3% on the day, underscoring a persistent bifurcation between large-cap growth/tech leadership and the broader market. That divergence left the Nasdaq as the only major index to post a weekly gain (+0.7% WTD), while the S&P 500 (-0.1% WTD) and DJIA (-1.7% WTD) finished the week lower. The week was dominated by the Fed’s 25-bp rate hike (unanimous 12-0 vote) to 3.75-4.00% and hawkish commentary from Chair Warsh, which drove the 10-year yield back toward its 2026 highs near 5.00%.
Crude oil moved inversely to yields, with WTI settling 1.8% lower at $100.24/bbl, essentially flat for the week. Market internals remained weak, with WaveFinder’s Primary Sentiment reading Bearish (490 bulls vs. 658 bears) even as the 4% Sentiment gauge ticked Bullish, reflecting a market where breadth continues to deteriorate beneath a resilient large-cap/tech surface.

Stock Spotlight
The day’s most notable single-stock story centered on Coinbase Global (COIN), which surged 11.66% to $194.25 (+$20.28), and Robinhood Markets (HOOD), which jumped 9.12% to $119.82 (+$10.01). Both stocks rallied following Thursday’s SEC announcement of an “Innovation Exemption,” a new regulatory framework allowing crypto exchanges to offer tokenized equities — a potentially significant expansion of the addressable market for both platforms. The move was reinforced by a broader crypto rally, with Bitcoin pushing past the $81,000 mark intraday.
The rally in COIN and HOOD provided a meaningful tailwind to the financials sector, which finished as one of only three S&P 500 sectors in positive territory Friday (+0.1%). The regulatory catalyst represents a structural development rather than a one-off earnings beat, positioning both companies at the center of the ongoing convergence between traditional securities markets and digital-asset infrastructure — a theme likely to remain in focus for investors in the sector going forward.
Bond Market & Treasuries
Treasuries closed the week on a weak note, with yields on the 10-year and shorter tenors settling near their 2026 highs, while the long bond outperformed for the week.
- 2-Yr: 4.74%, +5 bps on the day (+10 bps week)
- 3-Yr: 4.83%, +7 bps on the day (+10 bps week)
- 5-Yr: 4.86%, +6 bps on the day (+7 bps week)
- 10-Yr: 5.00% (4.998%), +5 bps on the day (+2 bps week)
- 30-Yr: 5.33%, +4 bps on the day (-3 bps week)
- 2s10s Spread: Tightened 8 bps to 26 bps (vs. 6-bp narrowing the prior week)
Key drivers: The Bank of Japan’s 25-bp rate hike to 1.25% (7-2 vote) failed to strike a hawkish enough tone to support the yen, raising concerns about potential Japanese selling of Treasuries if further currency intervention is needed. Fed Governor Bowman also commented on the SVB failure review, flagging potential stress-test revisions. The U.S. Dollar Index touched a seven-week high before settling little changed at 100.25 (+1.1% for the week).
Currencies: EUR/USD 1.1485 (+0.1%) | GBP/USD 1.3394 (+0.3%) | USD/CNH 6.6949 (-0.1%) | USD/JPY 156.68 (+0.5%)
Commodities
- WTI Crude Oil: $100.24/bbl, -1.8% (essentially 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 key policy rate by 25 basis points to 1.25% (7-2 vote), as expected. Governor Ueda’s lack of hawkish tone weighed on the yen, though it recovered more than half its overnight loss during the U.S. session.
- Japan: August National CPI +0.1% m/m (prior 0.5%), +1.9% y/y (prior 1.9%); Core CPI +1.7% (expected 1.8%, prior 1.8%)
- China: August FDI -5.3% YTD (prior -6.2%); China targeting CNY 3.5 trillion in pharmaceutical revenue by 2030
- South Korea: August PPI +0.2% m/m (prior -0.4%), +7.9% y/y (prior +7.7%)
- New Zealand: August FPI +0.3% m/m; trade deficit NZD 1.35 bln (narrower than expected NZD 1.775 bln deficit)
- Eurozone: July current account surplus EUR 27.6 bln (expected 30.7 bln, prior 35.1 bln); July construction output unchanged m/m
- U.K.: August retail sales +0.5% m/m (expected -0.2%), +2.4% y/y (expected +1.9%); core retail sales +0.6% m/m, +2.7% y/y
- Germany: August PPI +1.1% m/m (expected 0.6%), +4.6% y/y (expected 4.1%)
- ECB officials (including President Lagarde) reiterated a meeting-by-meeting approach to policy, emphasizing avoidance of second-round inflation effects
Economic Data
- Industrial Production (August): Unchanged m/m (consensus +0.3%) following an unrevised +0.2% in July; total IP +1.4% y/y. Softness attributed to a manufacturing output decline, potentially reflecting attrition after seven consecutive months of gains.
- Capacity Utilization Rate: 76.3% (consensus 76.4%), unchanged from July; 3.1 percentage points below its long-run average.
- Conference Board Leading Economic Index (August): -0.1% (consensus +0.2%) following +0.2% in July — a soft print reinforcing signs of decelerating momentum in forward-looking indicators.
Looking Ahead
Monday, Sept 21: Nothing of note scheduled.
Tuesday, Sept 22: Results of $69 billion 2-year Treasury note auction at 13:00 ET.
Wednesday, Sept 23: Weekly MBA Mortgage Index (prior -4.1%) at 7:00 ET; flash September S&P Global U.S. Manufacturing PMI (prior 53.9) and flash September S&P Global U.S. Services PMI (prior 56.5) at 9:45 ET; weekly crude oil inventories data.
Markets will continue to monitor the trajectory of the 10-year yield near the 5.00% threshold, follow-through in semiconductor and AI infrastructure names following Friday’s chip-led rally, and any incremental Fed commentary following last week’s hawkish 25-bp hike, as investors weigh the sustainability of narrow, mega-cap-driven leadership against continued broad-market and small-cap underperformance.
