Technology shares have regained momentum, but elevated inflation and Treasury yields leave Friday’s market direction unusually sensitive to Federal Reserve Chair Kevin Warsh’s Jackson Hole message.
Global markets entered Friday with a familiar tension between powerful corporate earnings and a less accommodating interest-rate backdrop. U.S. stock futures were little changed ahead of Federal Reserve Chair Kevin Warsh’s first Jackson Hole address, following a technology-led rally that pushed the Nasdaq Composite up 1.6% Thursday and lifted the S&P 500 by 0.7%. Dow futures were modestly positive Friday morning, while Nasdaq-100 futures slipped as investors reduced exposure before the central bank’s most closely watched communication of the week.
The immediate support for equities came from Nvidia (NVDA), whose shares surged 8.7% Thursday after the semiconductor company delivered another quarter of exceptional growth and projected roughly 70% revenue expansion for the fiscal year ending in early 2028. The forecast was substantially stronger than investors had expected and helped address a recurring concern hanging over technology valuations: whether artificial-intelligence infrastructure spending could continue expanding rapidly enough to justify the enormous market capitalization assigned to the sector’s leaders. Nvidia’s rally added roughly $440 billion in market value in a single session.
The effect extended well beyond chips. Salesforce (CRM) jumped more than 22% after reporting stronger results and improving its outlook, while cybersecurity and software names also advanced. The breadth of those gains mattered because investors have spent much of 2026 debating whether artificial intelligence would primarily benefit hardware providers or eventually translate into higher revenue and productivity across software companies. Thursday’s session offered evidence for the second scenario, at least temporarily, helping the market regain confidence in an AI trade that had become increasingly selective.
Yet the equity rally is taking place against a bond market that remains difficult to ignore. The 10-year Treasury yield was around 4.68% Friday morning, while the 30-year yield remained above 5%. Those levels represent a meaningful valuation constraint for stocks, particularly companies whose expected earnings are concentrated far into the future. Higher long-term yields raise the discount rate investors apply to future corporate cash flows and simultaneously make government debt a more credible alternative to equities. That dynamic helps explain why even exceptionally strong technology earnings have not produced an indiscriminate market surge.
Inflation is the central reason yields remain elevated. The Federal Reserve’s preferred personal consumption expenditures price index rose 3.7% from a year earlier in July, unchanged from June and still well above the central bank’s 2% objective. Core PCE, which excludes food and energy, increased 3.3% from a year earlier. Consumer spending rose only 0.2% during July, while real spending was essentially unchanged, presenting policymakers with an uncomfortable combination of persistent inflation and more moderate underlying demand.
That backdrop increases the significance of Warsh’s speech. The Fed kept its target rate at 3.50% to 3.75% in July, but the decision included three dissents in favor of a quarter-point increase. Investors therefore face a policy debate very different from the rate-cut discussions that dominated earlier phases of the post-pandemic cycle. A signal that the Fed remains prepared to tighten policy if inflation fails to improve could push short-term yields higher and challenge richly valued growth shares. A more patient message could instead reinforce the idea that current rates are sufficiently restrictive, giving equities additional room to advance.
The sensitivity is particularly high because economic growth is slowing without collapsing. Revised government data showed U.S. gross domestic product expanding at a 1.5% annualized rate during the second quarter, down from 2.1% in the first quarter. That is weak enough to make aggressive monetary tightening risky, but not weak enough to eliminate inflation as the Fed’s primary concern. For markets, the result is a narrow path in which slower growth is welcome only if it produces convincing disinflation rather than a deterioration in corporate profits.
Overseas trading reflected cautious optimism. Europe’s Stoxx 600 gained around 0.6% in early trading, with France’s CAC 40 and Germany’s DAX also advancing. Asian markets were more mixed: Japan’s Nikkei rose roughly 0.4%, while South Korea’s Kospi dropped about 1.8%. The divergence illustrates how strongly individual markets remain tied to different combinations of technology exposure, currencies, domestic monetary policy and commodity costs.
Commodities add another complication. Crude oil remains above levels seen earlier in the year as geopolitical risk in the Middle East keeps traders focused on potential disruptions to supply and shipping routes. Oil near the low-$80s per barrel may not by itself derail economic growth, but sustained energy inflation could make the Fed less willing to declare victory over prices. Gold, meanwhile, remains elevated above $4,600 an ounce, reflecting demand for protection against fiscal uncertainty, inflation and geopolitical instability even as equities trade at historically strong levels.
For investors, Friday’s setup reinforces a market structure that has become increasingly dependent on two variables: earnings growth strong enough to overcome high valuations, and interest rates stable enough to prevent those valuations from compressing. Nvidia has delivered convincingly on the first requirement. Warsh’s Jackson Hole address could determine how investors assess the second.
That leaves the market in a stronger position than it appeared earlier in the week, but hardly an uncomplicated one. Technology fundamentals remain formidable, volatility is subdued and global equities are generally holding firm. At the same time, inflation above 3%, a 10-year Treasury yield near 4.7% and a divided Federal Reserve reduce the margin for disappointment. The next stage of the rally may depend less on whether artificial intelligence continues growing and more on whether monetary policy allows investors to keep paying premium prices for that growth.
