Market Analysis
U.S. equities fell as the stabilizing effect of the Treasury’s intervention in the bond market faded quickly. The S&P 500 declined 0.87% to 7,641.16, the Nasdaq Composite lost 1.00% to 26,067.17, and the Dow Jones Industrial Average dropped 1.32% to 52,759.21.
Retail bellwether Walmart plunged 9.15% after reporting that revenue growth had slowed to its weakest pace in more than six years. The decline pushed its shares to their lowest level since November 2025 and added to concern about the durability of consumer demand.
Moderna, the mRNA cancer-vaccine leader that had surged 176.97% the previous day, fell 23.55% on Thursday. The recent healthcare rally also retraced broadly, with the Nasdaq Biotechnology Index down 2.92%.
Treasury Secretary Scott Bessent said more bond buybacks and a fiscal-consolidation plan were coming, but investors remained unconvinced and selling pressure in long-dated Treasuries resumed. Rising Treasury yields reflected renewed bond selling and weighed on equity risk appetite.
UBS CIO Ulrike Hoffmann-Burchardi said the intervention showed policymakers were concerned about the speed of the yield rise, but it did not fundamentally alter the outlook for interest rates. If inflation continues to cool, the Fed is unlikely to raise rates this year; persistently firmer price pressures would nevertheless keep tightening as an option.
Even as the broad market weakened, memory and optical-networking shares rebounded after two soft sessions. Following SK Hynix’s large shareholder-return plan, Samsung Electronics was reported to be considering a similar initiative, with speculation over the potential total rising from KRW 100 trillion to KRW 150 trillion. Unlike SK Hynix’s buyback-and-retirement approach, Samsung may favor a substantial special dividend.
SK Hynix rose 4.43%, Micron gained 3.97%, Lumentum advanced 6.24%, and Marvell added 5.79%. The move suggested that investors still see selective upside in AI infrastructure despite renewed pressure on the broader technology complex.
Alibaba also proved resilient. The shares initially fell more than 5% on concern about heavy AI capital expenditure, then reversed to close more than 1% higher after management said the certainty of returns on compute investment was very high and payback could be achieved within three years, with the period likely to shorten further.
In a pointed response to skepticism around AI-compute economics, Alibaba said Nvidia A100 chips purchased in 2020 and V100 chips purchased in 2018 remain nearly fully utilized by customers. The comments reinforced the view that sustained demand for compute capacity can support long-lived infrastructure investments, even as market leadership remains fragile.

Institutional Views
BlackRockCONSTRUCTIVE
Constructive on global equities, but favors diversification beyond concentrated AI leaders. BlackRock sees differentiated opportunity in AI infrastructure, power and industrial layers, while viewing healthcare equipment as a lower-correlation diversifier amid elevated expectations and geopolitical volatility.
Goldman SachsPOSITIVE
Goldman Sachs expects U.S. equities to grind higher as AI-trade leverage has been reduced and the economy remains resilient. It expects high single-stock dispersion to persist, rates to stay on hold, and credit investors to demand more compensation for heavy issuance.
UBSCONSTRUCTIVE
Constructive on equities, with preferred exposure to technology, utilities, healthcare, banks and commodities. UBS sees AI capex and adoption as supportive, but flags AI setbacks, inflation, trade tensions and sovereign-debt concerns as reasons to diversify and retain gold or quality-bond hedges.
