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

This company holds roughly $3M 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.

Winston Score History

The full picture

ZeroStack Corp. (ZSTK) does not appear in my knowledge base as a recognized public company in the Medical Distribution industry. It may be a very small, newly listed, or obscure firm for which reliable details are not available.

Given the financial profile — negative gross margins of -9.8%, operating margins of -27.5%, and a return on invested capital of -66.3% — the company appears to be early-stage or financially distressed, spending significantly more than it earns. A market cap near zero dollars further suggests it is a micro-cap or shell-like entity.

Without verified information about its specific products, customers, or operations, providing a detailed description would risk being inaccurate. Investors should consult official SEC filings such as the company's most recent 10-K or 10-Q for authoritative information about what ZeroStack Corp. actually does, how it generates revenue, and where it operates. These documents are available on the SEC's EDGAR database.

Revenue declining

ZeroStack's revenue is actually shrinking. In a growth stock, that removes the core investment thesis. The low Winston Score here may be warranted — unless there's a turnaround story.

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.
