Weekly Market Recap: Key Moves and What They Mean for Your Portfolio

As of August 10, 2026, US stock markets posted their strongest weekly performance in months, with the S&P 500 touching fresh record highs and the Nasdaq 100 posting its best week since April. The rally was fueled by three converging forces: falling oil prices, softening expectations for Federal Reserve interest-rate increases, and a renewed appetite for artificial intelligence-linked stocks. For long-term portfolio holders, the week illustrates both the power of macro shifts and the way individual stocks can move sharply even when they report solid results.

Equities Surge on Multiple Tailwinds

The S&P 500 advanced 3.58% for the week, with the Nasdaq 100 surging 5.19%, marking the largest weekly gains since April. The Philadelphia Semiconductor Index jumped 9.24% as investors rotated back into technology and semiconductor names after a difficult July. Globally, the Stoxx 600 gained 1.70%, the DAX rose 2.69%, and the CAC 40 added 2.41%, all reaching new record highs.

The move higher was accompanied by record options trading activity. More than four million S&P 500 index calls traded on Tuesday as the index surged above 7,700 for the first time ever, beating the previous call-trading record from May by 10%. The Cboe Volatility Index (VIX) fell to its lowest level since January, closing Friday at levels not seen in seven months.

However, not all large-cap earnings translated into gains. AMD shares fell 7% despite exceeding earnings expectations and issuing a third-quarter revenue forecast above estimates. The market's demand for even higher returns following the stock's earlier rally, combined with news that SpaceX selected Nvidia as its sole AI hardware supplier, weighed on the semiconductor name. SpaceX shares dropped 13.6% following its first post-IPO earnings report, despite nearly doubling revenues to $7.8 billion, as investors worried about the company's $16 billion in quarterly capital expenditures for AI infrastructure and the expiration of the first stock lock-up period.

Treasury Yields and Oil Prices Ease Lower

The 10-year US Treasury yield fell 9 basis points to 4.64%, driven by easing geopolitical friction across the Middle East. WTI crude fell 9% to $77 per barrel on the back of a potential deal between Iran and Oman to navigate a temporary shipping route through the Strait of Hormuz. Lower energy prices ease inflation pressures in the near term, though stabilizing oil fundamentals will take time before consumers feel relief at the pump.

Jobs Miss Reshapes Fed Rate Expectations

A key turning point came Friday when the US added just negative 23,000 jobs in July, missing analyst projections of 80,000, while the unemployment rate dipped to 4.1%. The unexpected weakness in payrolls, the first monthly jobs loss of the year, shifted market pricing dramatically. Market odds for a Federal Reserve rate hike in September fell from 60% to 40%, allowing stocks to push higher even as employment disappoints.

In Canada, the labor story was the opposite. Canada added 75,100 net jobs, lowering its unemployment rate to 6.4%, the lowest level since July 2024, which pushed Canadian Treasury yields slightly higher.

Credit Markets Signal Risk Appetite

Corporate bond issuers took advantage of the shift in sentiment. Alphabet Inc. raised $25 billion through a 10-part bond sale with maturities ranging from 2 to 40 years, drawing approximately $115 billion in demand, the third-largest investment-grade bond deal of the year. The longer maturity bonds offered a premium of 1.3% above US Treasuries, reflecting strong appetite for credit despite rates remaining elevated by historical standards.

What to Watch

Inflation Data Ahead: The week of August 11-15 brings US Consumer Price Index (CPI) data on Wednesday and Producer Price Index (PPI) data on Thursday. These reports will be closely watched by the market and the Federal Reserve as they reassess rate-path assumptions. Even with oil prices lower, core inflation metrics will be key to whether the soft-landing narrative holds.

Earnings Momentum: With 400 of the S&P 500 companies having already reported, the earnings season is becoming less intensive. Remaining results from companies like Cisco, Applied Materials, and CoreWeave will give investors a final read on AI infrastructure spending trends and whether capital allocation matches market enthusiasm.

Geopolitical and Currency Stability: The first coordinated US-Japan currency intervention in nearly three decades underscored fragile equilibrium in global markets. Watch whether geopolitical calm in the Middle East persists and whether the yen remains stable, as sudden reversals in either could ripple through Treasury and equity markets.

Divergence Between Indices: While the S&P 500 and Nasdaq 100 hit new highs, the Russell 2000 small-cap index also reached all-time highs but showed signs of weakness by week's end. Monitor whether small-caps and large-caps remain in lockstep or if relative rotation signals a shift in risk appetite.
