Block Shares (XYZ) Building Momentum, as Outperformance Continues

Block shares (ASX: XYZ) climbed 4.92% to A$113.08 to start the week, extending a post-earnings rally that has now pushed the fintech into overbought territory and raised questions about whether the Jack Dorsey-led company’s artificial intelligence and margin expansion narrative is running ahead of near-term fundamentals.

The advance leaves Block’s share price trading above both its 50-day and 200-day moving averages in a clean uptrend structure, but the 14-period relative strength index has reached 75.8, a level that typically signals crowded positioning and heightened risk of a cooling period. Volume of 121,944 shares suggests steady participation, yet the absence of a fresh catalyst today points to momentum carry rather than new information driving the move.

Block’s rally has most recently been supported by a strong first-quarter earnings beat in May and an upgraded full-year outlook that reframed the company’s controversial 40% workforce reduction as a structural, AI-enabled productivity leap rather than cyclical cost-cutting. Gross profit of US$2.91 billion rose 27% year-on-year, with Cash App gross profit surging 38% to US$1.91 billion and adjusted operating income jumping 56% to US$728 million. Management lifted full-year gross profit guidance to US$12.33 billion and adjusted earnings per share to US$3.85, up 62% from 2025, while targeting a 27% operating margin.

Fundamental Setup

The operational story is compelling. Block has embedded AI tooling across engineering, underwriting, and commerce workflows, claiming 2.5 times improvement in code-change productivity and aiming for more than US$2 million in gross profit per employee, roughly four times 2019-2024 levels. Cash App Borrow, the company’s consumer lending product, has become the single largest driver of incremental Cash App gross profit, underscoring the shift from payments novelty to credit-driven monetization.

Yet the market’s enthusiasm is colliding with a thin margin for error. Block’s second-quarter guidance calls for US$3.04 billion in gross profit, only US$20 million above consensus, leaving little cushion for any softness in US consumer spending or credit performance. Cash App Borrow’s rapid growth also raises loss provisioning risk if labour markets or consumer credit conditions weaken, a concern amplified by the fact that Square’s merchant business grew gross profit by a more modest 9% in the first quarter.

Broader fintech sentiment remains constructive but fragile. Block’s launch of Square High Yield Savings in June, offering 3.5% annual percentage yield to merchants, was positioned as a funding flywheel for the lending engine but drew a muted share-price reaction, suggesting investors want hard evidence of deposit growth rather than product headlines. The company also faces ongoing federal regulatory scrutiny and the ever-present risk that rising loan loss rates could pressure its premium valuation multiple.

View From The Street

Consensus among analysts points to a target price of A$153.28, implying 35.5% upside from current levels. That substantial gap supports the idea that today’s strength aligns with a constructive Street view rather than irrational exuberance.

However, the crowded nature of the bull case, with 35 of 36 analysts rating the stock a buy in recent coverage, complicates the picture. Such skewed sentiment can unwind sharply on any earnings miss or guidance reset, and the overbought technical reading suggests the risk-reward balance is shifting more toward execution risk than valuation derating.

The technical setup is consistent with a market that has fully priced in the first-quarter beat and is now testing the limits of the AI and margin expansion narrative ahead of second-quarter results in early August. For the rally to extend, Block will need to deliver on its thin guidance cushion and demonstrate that Cash App Borrow can scale without a material increase in credit losses.
