A red flag is a pattern in the numbers that deserves a closer look. It is a clue that something might need explaining — it is not a verdict. Experienced analysts treat red flags as questions to ask, not as proof of anything.

Signals worth investigating
| Signal | What it looks like | Why it is worth a look |
|---|---|---|
| Rapid debt growth | Borrowings rising much faster than profits | Interest costs can squeeze profit if the business slows |
| Falling cash flow | Operating cash flow shrinking year after year | The business may be collecting less or spending more |
| Profit up, cash flow down | Net profit rising while operating cash flow falls | Profits may be on paper rather than in the bank |
| Increasing receivables | Money owed by customers growing faster than revenue | Some sales may be hard to collect |
| Declining margins | Net margin falling even as revenue rises | Costs are rising faster than prices |
| Excessive dilution | Many new shares issued over a short period | Existing owners' slice shrinks; may signal a cash shortage |
| Large related-party transactions | Big deals with companies linked to owners or managers | Terms may not be fair to all shareholders |
| Unusual accounting changes | Changing how revenue or costs are recorded | Can make one year hard to compare with the last |
| Persistent negative free cash flow | Spending more on long-term assets than the business generates | The company keeps needing outside money to continue |
Nine patterns that analysts flag for a closer look.

Signals, not verdicts
What it looks like
Borrowings rising much faster than revenue or profits.
Why it may matter
More debt means more interest to service, and less resilience if business slows.
What to investigate
Why is the company borrowing? Is the new capital earning a return? Can cash flows cover interest?
Take increasing receivables as an example. Receivables are the money customers owe the company for goods already delivered. If they grow faster than revenue, it may mean customers are paying more slowly — but it may also mean a few large, reliable customers were given longer credit terms to win their business.
Large related-party transactions are another. A company dealing with firms connected to its own owners can be perfectly normal, but the terms should be clear and fair to all shareholders. That standard is sometimes called dealing at arm's length.
