Financial markets enter the week of 10–14 August after a strong rally in global equities, but investors now face an important test: can economic data and corporate earnings justify the optimism already priced into markets?

The S&P 500 and Nasdaq recently reached record levels, while lower Treasury yields and a softer-than-expected U.S. jobs report have strengthened expectations that the Federal Reserve may have more room to ease policy.

This week, attention shifts firmly toward inflation, consumer demand and the earnings of several companies closely linked to the artificial-intelligence investment cycle.

U.S. inflation takes centre stage

The most important economic event will be the release of the U.S. Consumer Price Index (CPI) for July on Wednesday, 12 August. Current expectations point to headline inflation of around 3.4% year over year.

The CPI report will be particularly important following the recent weakness in the U.S. labour market. A softer inflation reading could reinforce expectations of Federal Reserve rate cuts and provide additional support for equities, particularly growth and technology stocks.

Conversely, a hotter-than-expected CPI could push Treasury yields and the U.S. dollar higher and put pressure on expensive areas of the equity market.

On Thursday, 13 August, investors will receive the U.S. Producer Price Index (PPI). Producer prices will provide another indication of whether inflationary pressures are continuing to ease or whether companies are facing renewed cost pressures.

U.S. consumers provide another important signal

Friday brings another major data point with July U.S. retail sales. The market is looking for relatively modest growth, making the report important for assessing whether the American consumer remains resilient. The University of Michigan's preliminary August consumer-sentiment survey will also be released the same day.

The combination of inflation and consumption data could therefore shape expectations for both monetary policy and economic growth.

Europe: GDP and employment in focus

European investors will also receive important data on Friday, 14 August, when Eurostat publishes its flash estimates for second-quarter GDP and employment for the euro area and EU.

The European economy has shown some signs of improvement, with the European Commission reporting a recovery in economic sentiment during July.

The GDP and employment figures will help determine whether that improvement is translating into stronger underlying economic activity and could influence expectations for the European Central Bank.

AI earnings: another test for the technology rally

Corporate earnings will provide an equally important focus this week.

Among the most closely watched reports are CoreWeave and Super Micro Computer on Tuesday, Cisco Systems on Wednesday, and Applied Materials on Thursday.

CoreWeave is particularly interesting because investors are increasingly questioning whether massive AI infrastructure spending can translate into sustainable profits. Analysts expect very strong revenue growth, but also a wider quarterly loss.

Cisco will provide another perspective on AI infrastructure spending, particularly demand for networking equipment. Applied Materials, meanwhile, offers insight into semiconductor capital expenditure and the broader chip investment cycle.

Other notable names reporting include Rocket Lab, Nebius Group, JD.com and Tapestry, adding exposure to space technology, AI infrastructure, Chinese technology and consumer spending.

Oil and geopolitical risk remain on the radar

Markets will also continue watching developments surrounding the Strait of Hormuz and Middle East tensions. Oil prices moved higher on Monday as uncertainty over the reopening of the key shipping route increased. Brent crude was around $84 per barrel.

A sustained increase in oil prices would complicate the inflation outlook and could undermine some of the recent optimism around lower interest rates.

What investors should watch

The key question for markets this week is whether falling inflation, resilient consumption and strong corporate earnings can continue to support the equity rally.

For investors, the main signals are:

•12 August: U.S. CPI
•13 August: U.S. PPI
•14 August: U.S. retail sales and consumer sentiment
•14 August: Eurozone Q2 GDP and employment
•11 August: CoreWeave and Super Micro Computer earnings
•12 August: Cisco and Nebius earnings
•13 August: Applied Materials and JD.com earnings
•Throughout the week: Oil prices and developments around the
Strait of Hormuz

With equity valuations already elevated, good news may need to be very good to push markets materially higher. The combination of inflation data and AI-related earnings could therefore determine whether the recent rally extends further, or pauses as investors reassess expectations for interest rates, economic growth and corporate profitability.
