May 21, 20:00, U.S. Eastern Time, after the U.S. market opened its after-hours session, multiple stocks saw sharp moves.

D-Wave Quantum Inc. jumped over 20% in after-hours trading, far outperforming the broader tech space.
The surge came after the Trump administration announced the implementation of the “CHIPS and Science Act” support package, allocating a total of USD 2 billion to nine quantum computing companies in exchange for partial equity stakes. The move is aimed at consolidating U.S. leadership in quantum computing. Investors expect D-Wave to benefit from direct funding, enhanced R&D capacity, and closer government–industry collaboration, which could accelerate the commercialization of its quantum solutions. The policy-driven re-rating also lifted peers, with Arqit Quantum reportedly gaining more than 25% in the same session.

Take-Two traded actively in after-hours following the release of its Q4 results, with the stock fluctuating around modest gains.
The company reported a net loss of USD 59.5 million and EPS of USD -0.32, but net bookings reached USD 1.58 billion and revenue came in at USD 1.68 billion, beating the Ibes estimate of USD 1.572 billion. The better-than-expected top line helped ease concerns over near-term profitability, as investors focus on the company’s strong content pipeline and the potential earnings inflection from upcoming major titles. Analysts note that while margins remain under pressure from development and marketing costs, the beat on bookings supports a constructive medium-term outlook.

Workday saw noticeable after-hours volatility after releasing its Q1 FY2027 financial results.
The results offered fresh insight into the company’s operating momentum and financial health, with the market focusing on subscription revenue growth, operating margin trends, and updated full-year guidance. Investors are watching whether Workday can sustain double-digit growth in a more cautious enterprise IT spending environment, and whether efficiency gains in cloud infrastructure and sales productivity can translate into margin expansion. Early commentary from the Street suggests that any upside in guidance or stable renewal metrics would be key to supporting the current valuation.

Ross advanced in after-hours trading after posting much stronger-than-expected Q1 numbers.
Ross Stores reported pretax profit of USD 837.475 million, net income of USD 649.964 million, and sales of USD 6.010 billion, well above the Ibes estimate of USD 5.636 billion and ahead of its own initial guidance. The robust performance underscores resilient off-price demand and effective inventory and cost management. Analysts point out that Ross is benefiting from consumers trading down in a mixed macro environment, while disciplined store expansion and merchandising are supporting both traffic and ticket growth. The earnings beat and upbeat tone on demand are seen as catalysts for further re-rating in the off-price retail space.
