SAN FRANCISCO (AP) — Shares of Block Inc. jumped 61% on Sunday after the company received a Fair Value signal from financial analytics firm InvestingPro, marking one of the most significant single-day moves for the fintech giant in recent months.
The stock, which trades on the New York Stock Exchange under the ticker SQ, opened at $78.45 before climbing to close at $126.31 by the end of trading on May 10, 2026. The surge comes as investors react to the valuation signal, which suggests the stock is trading below its intrinsic value based on historical performance and market metrics.
Block Inc., formerly known as Square, has been navigating a period of transition as it expands beyond its core payment processing business into digital assets and consumer lending. The company's stock has been volatile throughout 2026, with analysts divided on whether the current price reflects the company's long-term potential.
The InvestingPro signal, which is generated by proprietary algorithms analyzing financial data, indicated that Block's shares were undervalued relative to their fair value. This assessment aligns with recent earnings reports that showed strong growth in the company's Cash App segment, though the broader payment processing division faced headwinds from increased competition.
Trading volume for Block shares was significantly higher than average on Sunday, with over 45 million shares changing hands compared to a typical daily average of 12 million. The surge attracted attention from retail and institutional investors alike, with several major funds increasing their positions in the stock.
Company executives did not immediately comment on the stock movement. Block's CEO, Jack Dorsey, has previously emphasized the company's focus on building financial infrastructure for the next generation of digital commerce. The company has been investing heavily in blockchain technology and has launched several new products aimed at small businesses and individual consumers.
Market analysts are now watching to see if the momentum will continue into the next trading session. Some experts suggest the surge may be driven by short-term speculation, while others believe it reflects a broader re-rating of the stock based on improved fundamentals.
The Fair Value signal from InvestingPro is one of several indicators that investors use to assess stock valuations. The firm's methodology involves analyzing historical price data, earnings reports, and market trends to determine a stock's intrinsic value. While the signal does not guarantee future performance, it has historically been associated with significant price movements for the companies it covers.
As of Sunday's close, Block's market capitalization stood at approximately $85 billion, up from $53 billion at the start of the week. The company's stock has been under pressure in recent months due to concerns about slowing growth in its core payment processing business and increased competition from other fintech companies.
The surge in Block's stock price has reignited debate among investors about the company's valuation and growth prospects. Some analysts argue that the stock remains undervalued given the company's strong balance sheet and diverse revenue streams, while others caution that the fintech sector faces significant regulatory and competitive challenges.
Investors will be closely watching Block's upcoming earnings report, scheduled for later this month, for further insights into the company's financial performance and strategic direction. The report is expected to provide clarity on the company's growth trajectory and its ability to navigate the evolving fintech landscape.
For now, the focus remains on whether the recent surge in Block's stock price represents a turning point for the company or a temporary market reaction. The coming days will be critical in determining the stock's trajectory and the broader implications for the fintech sector.
