Deep Value: cash covers more than 100% of the stock price

This company holds roughly $6M in cash and investments — more than its entire stock-market value, based on its latest quarterly filing. You're paying very little for the actual business. Sometimes that's a genuine bargain or a takeover target, sometimes it's cheap for a reason. Not a buy signal on its own — always ask why it's this cheap.

Cardio Diagnostics Holdings is a small biotechnology company focused on using artificial intelligence and genetic testing to detect heart disease earlier than traditional methods. Its main product is a blood-based epigenetic test that looks at DNA patterns to assess a person's risk of cardiovascular conditions like heart attacks. The company targets patients, doctors, and health systems looking for more precise ways to identify heart disease risk before symptoms appear.

The company earns revenue by selling its diagnostic tests, though it currently generates very little revenue and spends far more than it brings in — reflected in deeply negative margins. It operates primarily in the United States and is a micro-cap company with a very small commercial footprint. The biggest risk facing Cardio Diagnostics is achieving meaningful commercial adoption and scaling revenue fast enough to avoid running out of cash, as the company depends heavily on continued financing to fund its operations.

Revenue accelerating

Cardio Diagnostics Holdings grew revenue 185% year-over-year and the growth rate is speeding up. That's the kind of momentum growth investors look for — the question is whether margins can follow.

The Winston Score above measures business quality today. Growth stocks often score lower because they invest in the future rather than maximising current profits. These metrics show what matters most for evaluating that future.
