Markets show optimism—but 3 key events could shape the Week

Markets enter the week with a constructive—but highly event-sensitive—risk tone. Investor sentiment will likely be shaped by three interconnected catalysts: July’s PCE inflation report, Federal Reserve Chair Kevin Warsh’s first Jackson Hole address as chair, and earnings from several strategically important technology and artificial intelligence companies.

The timing of these events is critical. The inflation data will be released before Chair Warsh’s speech, giving him a chance to interpret the latest figures and potentially influence expectations for the Fed’s September meeting. Meanwhile, corporate earnings—most notably from Nvidia—will test whether the substantial investments in artificial intelligence are translating into sustainable revenue and earnings growth.

PCE inflation data: The Week’s First Major Test

Wednesday’s Personal Consumption Expenditures (PCE) inflation report stands out as the week’s marquee economic event. Scheduled for August 26, the report could directly shape market expectations for the Federal Reserve’s interest rate trajectory.

The report includes both headline and core PCE price indexes and holds particular significance since PCE is the Fed’s preferred inflation gauge. Although the urgency for a September rate hike has softened, markets still anticipate the possibility of one more increase before the end of 2026. A softer-than-expected core reading could bolster risk assets by easing concerns about further tightening, whereas a hotter-than-expected print might reignite fears of rate hikes and pressure equity valuations.

Technology and AI Earnings: Nvidia in the Spotlight

Investors are also preparing for one of the busiest earnings weeks of the summer. Nvidia, Salesforce, and CrowdStrike are set to report after the market closes on Wednesday, followed by Marvell Technology on Thursday.

Nvidia will be the focal point. As the leading supplier of computing infrastructure for AI, its results will provide critical insight into AI investment, data-center demand, and the sustainability of growth in this sector.

Salesforce and CrowdStrike will offer additional perspectives on enterprise software and cybersecurity spending, while Marvell’s results may reveal trends in demand for custom AI chips and broader data-center infrastructure investment.

Together, these earnings will help investors evaluate whether AI-related spending remains broad-based, profitable, and constrained by capacity—or if returns are starting to fall short of market expectations.

Kevin Warsh’s First Jackson Hole Address as Fed Chair

Federal Reserve Chair Kevin Warsh is scheduled to speak at the Jackson Hole Economic Policy Symposium on August 28. Markets will closely watch for clues about the Fed’s policy direction.

The symposium gives Chair Warsh a prominent platform to explain how he views the balance among persistent inflation, economic growth and financial stability. Markets will focus not only on his immediate policy message but also on the broader framework likely to guide the Fed under its new leadership.

Because the PCE report will already be available, Warsh may use the address to place the latest inflation figures in context. His tone could meaningfully shape expectations for the September meeting and the direction of interest rates through year-end.

Overall assessment

The week ahead promises significant market activity with several high-volatility events scheduled. The PCE report will set the inflation backdrop, Nvidia and other tech companies will test the earnings narrative, and Warsh’s Jackson Hole speech will frame the Fed’s response.

The most constructive combination for risk assets would be moderating core inflation, a balanced or mildly dovish Fed message, and AI-company guidance showing that demand remains strong, profitable and constrained by available capacity. The principal downside risk is the opposite scenario: persistent inflation, a hawkish policy signal and evidence that AI spending is slowing or generating weaker returns.

Investors should therefore distinguish between two separate sources of volatility: macro-driven valuation risk and company-specific earnings risk. With both forces in play, the market’s bullish tone faces one of its most important tests of the summer.
