Executive Summary
U.S. equities finished higher, but the headline hid weak breadth. SPY gained 0.5%, QQQ rose 0.4%, and the Dow added 0.5%. Equal weight fell 0.4% and small caps lost 1.4%. Investors bought companies that could prove earnings and sold the broader promise of easier money.
Nvidia supplied the proof. Reuters reported that the company beat high expectations and forecast 70% revenue growth in the next fiscal year. The shares jumped almost 9% on Thursday, yet gained only 1.3% from Friday to Friday. A great quarter cleared the earnings test. It did not erase the rate test.
Technology gained 1.3% and financials rose 1.1%. Energy lost 1.5%. Falling oil helped the consumer inflation outlook at the margin, but July PCE inflation was still 3.7% year over year and core PCE was 3.3%. Both indexes rose 0.2% in July.
Fed Chair Kevin Warsh then made the policy message explicit at Jackson Hole. He said the Fed may need to raise rates if inflation does not move toward 2%. The 2-year Treasury yield rose 10 basis points to 4.34%. The long end rallied, flattening the curve.
Global ex-U.S. equities slipped 0.2%. Japan gained 0.7%, while Europe fell 0.8% in dollar terms. Emerging markets were flat. A stronger dollar took back part of the prior week's liquidity move and made U.S. mega-cap earnings more attractive than foreign beta.
Crypto failed to hold its liquidity-led surge. Bitcoin fell 0.9% to about $77,739 and ether lost 3.2% to roughly $2,442. The dollar rose, the front end repriced, and the assets with no current cash flow gave back ground.
Oil and gold also reversed. WTI's ETF proxy fell 3.7%, Brent's fell 4.3%, and gold lost 3.4%. Copper fell 0.8%. Lower commodity prices reduced immediate inflation pressure, but the signal was weaker global nominal demand, not a clean soft landing.
The main message is narrow. The market will fund growth that produces cash now. It will punish growth that depends on lower rates later. That favors proven AI infrastructure earnings and selected financials over small caps, speculative technology and liquidity trades.
US Stock Market
SPY rose 0.5%, QQQ gained 0.4%, and the Dow added 0.5%. IWM fell 1.4% and RSP lost 0.4%. That gap matters. A healthy easing trade should lift small companies and equal weight because lower financing costs help weaker balance sheets most. The opposite happened.
Technology gained 1.3% and financials rose 1.1%. Financials benefit when firm nominal activity supports loan demand and credit losses remain low. Technology needed a harder filter. Nvidia's results supported the companies selling scarce compute. They did not validate every software or AI-adjacent valuation.
Why would this setup pay? Many portfolios own broad growth because they expect policy relief to lift all duration. Persistent inflation blocks that relief. Firms with current earnings can compound through a high hurdle. Firms that need cheap capital cannot. The market is starting to separate the two.
Leadership Read
Nvidia confirmed that AI infrastructure demand remains real.
Firm activity and limited credit stress supported current earnings.
The average large company did not share the index gain.
Higher front-end rates kept the financing burden alive.
Global Markets
VXUS fell 0.2%. Europe's ETF proxy lost 0.8%, emerging markets were flat, and Japan gained 0.7%. The stronger dollar reduced dollar returns from overseas assets. More important, U.S. markets had a company-specific earnings catalyst that other regions lacked.
Europe's July inflation rate was 2.9%, according to the ECB data portal. The eurozone composite PMI had reached 52.1 in August, but the region still faces an awkward mix of positive activity and high energy-linked inflation. Falling oil helped this week. It did not remove the policy constraint.
Japan's equity proxy rose even as Tokyo core inflation accelerated to 1.8% in August from 1.7%. The gain says investors still value Japan's improving nominal earnings. The stronger inflation print also keeps another Bank of Japan hike in play. That caps how far exporters can rerate without faster profit growth.
Cryptocurrency Market
Bitcoin fell 0.9% from Friday to Friday, ending near $77,739. Ether dropped 3.2% to about $2,442. Both had surged the prior week after Treasury expanded debt buybacks. This week's stronger dollar and higher 2-year yield removed part of that support.
Read-Through
The trade still looks driven by liquidity rather than a new adoption catalyst. That can pay because crypto reacts quickly to marginal dollar supply. It also fails quickly when the Fed tightens the expected path. Bitcoin holding above its pre-buyback level is constructive. Ether's larger loss shows the market moved back toward quality even inside crypto.
Economic Indicators, Statistics and News
United States
Headline and core PCE prices each rose 0.2% in July. Headline inflation held at 3.7% year over year and core held at 3.3%. Personal income rose 0.4% and nominal spending rose 0.2%, while real spending was flat. Consumers earned more but did not convert it into real demand.
Second-quarter real GDP grew at a 1.5% annual rate. The August composite PMI was much stronger at 56.0 and pointed to growth near 3% in the third quarter, led by services. The hard and survey data disagree on speed. Both say the economy is still expanding.
University of Michigan sentiment fell to 51.7 from 55.2 in July. Thirty-six percent of respondents named inflation as the main problem, versus 6% for unemployment. The consumer's complaint is purchasing power, not access to work. That is a harder problem for the Fed to solve with easier policy.
Federal Reserve
Warsh said inflation progress has been modest and the Fed may have work to do if prices do not move toward target. About half of the PCE basket was rising at more than a 3% annual rate. The message shifted the debate from delayed cuts toward possible additional tightening.
Global
Eurozone and United Kingdom
The eurozone's August composite PMI was 52.1 and the U.K. reading was 52.5. Activity expanded in both regions. Europe's inflation problem remains more exposed to energy than America's. This week's oil decline helps near-term bills, but central banks still need several months of lower prices before the constraint changes.
Japan
Tokyo CPI excluding fresh food rose 1.8% year over year in August, up from 1.7%. The measure excluding fresh food and energy reached 2.0%. Domestic inflation is no longer just an imported-energy story. That strengthens the case for another Bank of Japan hike.
China
Emerging-market equities were flat and copper fell 0.8%. Neither price confirms a new Chinese demand impulse. Until fiscal support reaches household spending, property transactions or private investment, China remains a policy expectation rather than a verified growth acceleration.
Foreign Exchange Markets
The dollar proxy rose 1.0%. Euro, sterling and yen proxies each fell about 0.8%. The move matched the front-end rate signal. U.S. inflation remained high, Warsh reopened the door to hikes, and the 2-year yield rose 10 basis points.
A stronger dollar tightens global financial conditions without a formal Fed move. It reduces translated overseas earnings, pressures dollar borrowers and removes support from commodities and crypto. If the dollar keeps rising while long yields fall, the market is pricing U.S. policy tightness rather than a global growth boom.
Commodities and Energy Markets
WTI's ETF proxy fell 3.7% and Brent's fell 4.3%. Gold lost 3.4% and copper fell 0.8%. Energy gave back part of the prior week's Iran premium. The stronger dollar amplified the decline across the complex.
Commodity Read
Lower oil is useful because it reduces the next inflation impulse and supports consumer real income. Gold's decline says immediate demand for monetary protection eased. Copper's weakness is the warning. The commodity move did not reflect stronger industrial demand or a broad global expansion.
Debt and Fixed Income Markets
From August 21 to August 28, the 2-year Treasury yield rose 10 basis points to 4.34%. The 10-year slipped 1 basis point to 4.73% and the 30-year fell 5 basis points to 5.22%. The curve flattened as investors raised the near-term policy path but bought long bonds.
Up 10 basis points after PCE and Jackson Hole.
Down 1 basis point as long growth expectations held.
Down 5 basis points as oil fell and the curve flattened.
TLT gained 1.0%, investment-grade bonds rose 0.4%, and high yield added 0.2%. Credit remained calm. The market is pricing a policy problem, not a balance-sheet recession. That distinction supports profitable equities but works against small companies that must refinance at the front end.
What to Watch Next Week
- August payrolls on September 4. Consensus is near 50,000 jobs with unemployment at 4.1%. A large beat would strengthen the hike case. A miss with higher unemployment would challenge financials and small-cap earnings.
- ISM manufacturing and services. S&P Global's flash survey showed strong service growth. ISM needs to confirm that acceleration.
- Broadcom earnings. Nvidia proved demand at the GPU layer. Broadcom will test custom silicon, networking and hyperscaler spending breadth.
- The 2s10s curve. More flattening would confirm tighter policy against stable long-run growth. A bear steepening would be worse because it would raise the hurdle across all durations.
- Dollar follow-through. Another weekly gain would pressure crypto, commodities and international returns.
- Equal weight and small caps. They must regain relative strength before this becomes a broad equity rally rather than an earnings-led mega-cap trade.
