SK Hynix vs. Monday.com: Which Technology Stock Is a Better Buy in 2026 Amid the Artificial Intelligence Boom?

As the artificial intelligence boom continues to evolve, investors must choose between high-performance hardware and scalable enterprise software. Should you buy SK Hynix (NASDAQ:SKHY) or Monday.com (NASDAQ:MNDY) today?

SK Hynix builds the physical memory that powers global AI infrastructure, while Monday.com provides the software platform that helps teams organize complex modern workflows. These companies operate at opposite ends of the technology stack. Comparing them reveals whether you prefer the cyclical upside of hardware or the recurring revenue of software-as-a-service.

The case for SK Hynix

SK Hynix produces high-performance memory products that are essential for modern data centers and consumer electronics. It focuses on Dynamic Random Access Memory (DRAM) and NAND flash chips used in high-end artificial intelligence servers and mobile devices. Because it provides the hardware backbone among semiconductor stocks, its growth is tied closely to the infrastructure needs of major cloud providers.

In its 2025 fiscal year (FY), revenue reached $68.6 billion, representing a significant increase of 46.8% compared to the previous year. The company reported a net income of $30.3 billion for the same period. This resulted in a net margin of 44.2%, which measures the percentage of revenue remaining as profit after all costs are paid.

As of its December 2025 balance sheet, the debt-to-equity ratio was 0.2x. This ratio compares total debt to shareholder equity, indicating the company uses a conservative amount of debt to fund its operations. The current ratio stands at 1.9x, which measures the ability to pay off short-term liabilities with assets that can be turned into cash quickly. Free cash flow reached $17.5 billion in FY 2025, representing the cash left over after the company pays for its operations and capital investments.

The case for Monday.com

Monday.com offers a cloud-based platform that allows teams to build custom work management tools for various business needs. The company serves approximately 250,000 customers globally, providing software for project management, customer relationship management, and development workflows. By selling subscription-based access to its platform, the company aims to create a steady stream of recurring revenue from diverse industries.

In FY 2025, revenue reached $1.2 billion, reflecting a growth rate of 26.7% over the prior year. The company reported a net income of $118.7 million during this period. Its net margin was 9.6%, indicating the portion of total sales that is converted into actual profit for the business.

As of its December 2025 balance sheet, the debt-to-equity ratio was 0.3x, helping to gauge the company's financial leverage. The current ratio was 2.5x, demonstrating its ability to cover short-term obligations with liquid assets. Free cash flow for FY 2025 was $309.9 million. Note that stock-based compensation (SBC) represented 53.1% of operating cash flow, which inflates reported cash generation since SBC is a non-cash expense added back in the cash flow statement.

Risk profile comparison

SK Hynix faces risks related to the cyclical nature of the memory market, where chip prices can drop sharply when supply exceeds demand. The company must also manage high capital expenditures to maintain its manufacturing facilities and technological edge. Furthermore, competition from Micron Technology and Samsung Electronics remains a constant threat to its market share and pricing power.

For Monday.com, the primary risk involves intense competition in the enterprise software market. If larger competitors integrate similar features into their established software suites, it could lead to higher customer churn or lower pricing. The company also faces risks if businesses reduce their total software spending during economic downturns or periods of tighter corporate budgets.

Valuation comparison

SK Hynix looks cheaper based on its Forward P/E ratio, while Monday.com trades at a lower P/S ratio.

Which stock would I buy in 2026?

The tailwind of artificial intelligence has boosted the fortunes of SK Hynix while AI's impact on Monday.com's business remains murky. That said, the memory sector, in which SK Hynix operates, is known for cyclical ups and downs. The big question is the timing around when the inevitable downturn will hit.

In weighing such pros and cons of each company, the stock I would invest in right now is SK Hynix. The South Korean tech giant achieved record high revenue in the second quarter, a testament that demand for its products remains strong.

A key driver for SK Hynix's future growth is the expansion of data centers around the world. As these facilities add computing power to support evolving AI systems, memory solutions are likely to remain in need. The company is also signing multi-year agreements with tech giants to ensure its revenue remains robust for the long term. One of these deals is with AI semiconductor chip leader Nvidia.

Moreover, while Monday.com's share price valuation looks low from a sales multiple perspective, its forward P/E ratio is far higher. Since the forward earnings multiple looks toward future earnings, this suggests SK Hynix is expected to deliver robust profits in the months ahead, and its valuation hasn't caught up yet, making now a good time to pick up shares.
