Weekend Update, August 24th, 2026
A Treasury bond shock ended the S&P 500 and Nasdaq’s three-week winning streaks, but low volatility and earnings kept the move lower contained versus a broad risk-off decline.
Key Takeaways Last Week
U.S. stocks retreated from record territory. The S&P 500 fell -1.44%, the Nasdaq Composite lost -2.17%, the Dow declined -0.92%, and the Russell 2000 fell -1.73%. Year to date, the prior indexes have gained 12.10%, 12.50%, 10.77%, and 21.49%, respectively.
- Interest Rates and oil drove the tape. The 10-year Treasury finished near 4.74% and the 30-year near 5.27% after an unusually volatile week centered Treasury intervention.
- Rotation was sharp. Health care (+4.32%), materials (+2.28%), and energy (+2.58%) rose while information technology (-3.35%), industrials (-3.31%), and utilities (-3.04%) declined.
- The economic message stayed mixed. August composite PMI accelerated to 56.0, and jobless claims fell to 206,000, while July housing starts dropped -12.4%. The consumer remains mixed as Walmart reported its slowest U.S. comparable-sales growth in more than six years.
- It’s a material world. Bloomberg data showed oil +5.62%, gold +5.56%, and silver +7.49%; the dollar index fell about 0.9%, and bitcoin rose from below $63,000 to above $77,00.
- This week. July PCE, a Q2 GDP revision, durable goods, Nvidia earnings, and Fed Chair Kevin Warsh’s Jackson Hole keynote all arrive between Wednesday and Friday.

The week reversed the prior leadership pattern: the Nasdaq underperformed the Dow by 125 basis points as higher interest rates hit long-duration growth. Small caps also lagged.

Breadth & Participation

Eight of 11 S&P 500 sectors declined. Rotation and weaker participation, not wholesale liquidation.
Small caps underperformed: Russell 2000 -1.73% versus S&P 500 -1.44%. However, the Russell remains the best major U.S. index year to date at +21.49%.
Friday breadth improved, but one strong session did not reverse the weekly deterioration.

Developed markets were softer while emerging markets held up: MSCI EAFE fell -0.36% for the week and remained +12.73% YTD; MSCI Emerging Markets gained +0.88% and was +22.82% YTD. Japan was among the weakest major markets as government-bond yields led the global tech selloff, while South Korea produced a sharp late-week rebound led by memory names, Samsung Electronics and SK Hynix.
The pressure was interest rate-sensitive, but emerging markets were resilient.

Volatility & Risk Sentiment
VIX closed at 15.13. Options markets are not pricing in near-term stress events until post 3q26.
Credit was more cautious on massive AI debt issuance. Bberg U.S. High Yield returned -0.18%, while broad investment-grade credit was flat. The signal is duration/fiscal stress first.

Bonds, Credit & Interest Rates
Treasury’s surprise decision to at least double its 10-to-30-year liquidity-support buybacks to $4 billion per operation, beginning September 9, briefly pulled the 10-year yield toward 4.64%. Most of that rally reversed by Thursday. That failure to hold the move shows the market wants compensation for supply and fiscal uncertainty even with official, yet small, liquidity support.

Economic Data, Monetary Policy & Earnings
Fed minutes: officials voted 9-3 in July to hold the target range at 3.50%-3.75%. “Many” judged tighter policy would likely be needed if inflation did not decline.
Fed moves: a September hold remained the base case with odds of a September hike near 30%.
Growth: Slowing but August flash U.S. composite PMI rose to 56.0 from 54.5, the fastest output growth in 52 months. Initial jobless claims fell 6,000 to 206,000, consistent with low layoffs.
Housing recession: July starts fell -12.4% to a 1.239 million annualized rate; single-family starts fell 9.9%. Permits rose 5.0% to 1.443 million.
Earnings boom: FactSet’s August 7th report showed, 88% of the S&P 500 reported, blended Q2 earnings growth was 50.4%, but fell to 32.0% excluding Alphabet and Amazon.

Consumer Stress Commentary
Walmart supplied the clearest caution flag. U.S. comparable sales excluding fuel rose 2.6%, below expectations and the slowest pace in more than six years. The company raised its full-year outlook.
Off-price retailer Ross Stores reported better-than-expected results and saw new-customer growth. The reports support a value-seeking and trade-down narrative rather than a uniform demand recession. Housing remains a pressure point because construction costs, mortgage rates and long yields are high.

Commodities, Currencies & Macro Assets
Message: oil represented inflation and geopolitical risk; gold and bitcoin represented fiscal/liquidity hedges. With the dollar weaker, consistent with a term-premium shock not a growth acceleration.

Liquidity Conditions
Treasury long-end buybacks are liquidity-support operations, small “operation twist”. They do not eliminate net issuance or the fiscal supply problem.

Flows & Positioning
Demand in crypto: U.S. spot-bitcoin ETFs netted more than $1 billion of weekly inflows, the strongest since January, alongside a leveraged short squeeze.

What Matters This Week
The four market tells:
Inflation: a core PCE print above 0.2% m/m would challenge the September-hold consensus and could push the 30-year through the roughly 5.30% area the market has been testing.
AI earnings: Nvidia validating revenue growth and the durability of margins and customer financing capacity as capital costs rise.
Fed Policy: Warsh reconciling inflation concerns with Treasury’s effort to improve long-end liquidity.
Geopolitics: Oil above $90 keeps the inflation concerns high.
Sources: BEA, Kansas City Fed, Kiplinger
Bottom Line
Last week weakened the equity tape without breaking; volatility stayed calm, investment-grade credit was flat, and hard assets soared. A benign PCE print plus strong Nvidia guidance could re-open the AI/momentum/growth trade; a hot inflation print, a 30-year yield above roughly 5.30%, or a hawkish Jackson Hole message would reinforce the rotation away from long-duration growth. The key question is whether interest rates stabilize before tech leadership narrows further.
