Look, there are certain things you just notice in companies if you’ve spent enough time digging. They’re like little warning bells, subtle at first, but if you see enough of them stacking up… yeah, maybe it’s time to hit pause.
Some of these red flags on their own? Not a big deal. Maybe it doesn’t even bother you. But when you start noticing multiple things, it paints a picture. And that picture? Usually not great. You’ve got the numbers, the filings, the public info. That’s your advantage. Use it. Don’t ignore it.
In fact, this is exactly what “The 7 Red Flags That Tell You A Company Is About To Collapse” is all about—spotting those subtle warning signs before they turn into real problems. Here are the ones I watch for, and honestly, if you’re serious about investing, you need them in the back of your mind all the time.
Red Flag #1: Free Cash Flow That Never Seems To Cooperate
Cash is… well, cash. It’s not sexy, but it’s life. Free cash flow is just the money left after a company pays for its day-to-day operations and all the stuff it needs to keep the lights on.
If a company is constantly burning cash, that’s not just “we’re growing fast.” That’s a signal that something is off. Either they’re terrible at making money, or they’re chasing growth like it’s the only thing that matters. Either way, sooner or later they’ll need more money—debt, issuing shares, whatever.
So, what screams trouble here:
- FCF negative for years in a row
- Spending a ton on capex but not seeing results
- Constantly raising money or piling on debt
- No clue when they’ll actually break even
- Promises of profits that never show up
If they can’t generate cash, don’t pretend it’s “all about growth.” Cash is survival.
Red Flag #2: People Keep Quitting at the Top
Nothing messes with a company more than leadership that keeps switching. CEOs, CFOs, anyone important jumping ship all the time? That’s a sign the company is unstable. Board fights, broken strategy, bad culture… take your pick.
A company is like a ship. You don’t want a new captain every year. It’s chaos. Frequent top-level turnover usually ends badly.
Watch for:
- CEO/CFO switching every 1–2 years
- Sudden resignations that seem out of nowhere
- Interims hanging around too long
- Big severance packages flying around
- No plan for who’s next
Stable leadership isn’t everything, but instability at the top is almost always bad news.

Red Flag #3: Financials That Feel Like a Riddle
If you’re staring at the numbers and thinking, “What the hell is this?”, that’s already a red flag. Overly complicated accounting can hide real problems, or make the company look better than it is. Non-GAAP numbers, weird segments, endless footnotes… if it’s messy, that’s on purpose.
If you can’t explain it in simple terms, maybe don’t invest. That’s my rule.
Look for:
- Crazy long footnotes and constantly changing accounting rules
- Reporting segments that make no sense
- Adjusted earnings that feel too good to be true
- Late filings
- Frequent restatements
If it’s confusing on purpose, there’s usually a reason.
Red Flag #4: One Customer Holds the Power
I hate this one because it’s common. One or two big customers driving most of the revenue is dangerous. Lose one, and the company could collapse. Also, big customers can squeeze margins because they know the company needs them.
Diversification isn’t glamorous, but it saves you from disaster.
Signs of trouble:
- Single customer = 20%+ revenue
- Not spreading clients in new markets
- Losing a major customer with nothing lined up
- Dependence on government or volatile industries
- Hiding who their customers are
If your future hinges on one client, it’s a lottery ticket. Not an investment.
Red Flag #5: Insiders Selling Like Crazy
If the people running the company are selling their stock all the time, maybe you should think twice. Some selling is normal. Everyone has bills. But constant, big sales? That usually means they don’t believe in the business.
Especially sketchy if it’s right after buybacks or big hype moments. Insiders only buy for one reason: they think the stock will go up. Selling? That’s a red flag.
Watch for:
- Multiple executives selling at once
- Selling after hype moments or buybacks
- No insider buying to balance it out
- Stock-based pay followed by immediate cashing out
- Selling before major announcements
If they’re offloading, why would you want in?
Red Flag #6: Debt That’s Out Of Control
Debt can be fine. Too much debt? That’s a disaster waiting to happen. High debt means less flexibility, higher risk, and interest eating profits. Even good companies can crumble if they’re overleveraged, especially when the market gets rough.
Debt doesn’t just magnify profits—it magnifies mistakes. One bad quarter, and suddenly you’re looking at bankruptcy or fire sales.
Signs:
- Debt-to- EBITDA over 3x in cyclical businesses
- Interest coverage below 4x
- Debt rising while cash flow falls
- Always refinancing just to survive
- Big debt maturing soon with no plan
Too much debt? Stay cautious.

Red Flag #7: Margins That Keep Sliding
Margins tell you how much control a company has over its costs and pricing. If gross margins are dropping, that usually means trouble. Maybe competition is eating them alive, maybe costs are rising, maybe they’re just losing power to set prices.
Margins can fail quietly at first, but over time they crush profits. Don’t ignore this.
Look for:
- Declining gross margins over years
- Margins below peers
- Costs going up without being able to raise prices
- Management keeps blaming “temporary issues”
- No guidance or clarity about future margins
Margins show if the company is in control—or not.
Right now, these seven are enough to make you stop and really think about a company. Alone, maybe one seems minor. But stacked together? Patterns emerge, and patterns matter.
Conclusion
At the end of the day, red flags aren’t guarantees, but they’re warning signs you ignore at your own risk. Negative cash flow, messy leadership, too much debt, insider selling… these aren’t small things. They stack up, and if you see enough, it’s worth hitting pause and asking why.
Investing isn’t about chasing hype—it’s about spotting patterns, paying attention to the numbers, and trusting your gut. Keep an eye on these signs, and you’ll avoid the obvious mistakes most people make. Simple as that.
Frequently Asked Question (FAQs)
Q. Are red flags always a reason to avoid a stock?
Ans: Not always. One red flag alone might be fine, but multiple red flags stacking up? That’s usually a warning. Think of it like smoke—you might be okay if it’s one puff, but a lot of smoke means fire.
Q. Can a company have negative cash flow and still be a good investment?
Ans: Yep, especially fast-growing companies. The key is whether there’s a clear path to profitability. If negative cash flow keeps going for years with no explanation, that’s a problem.
Q. How much debt is too much?
Ans: There’s no hard number, but generally, if debt is growing faster than cash flow, or the company struggles to pay interest, it’s risky. Look at debt-to-EBITDA and interest coverage ratios as a rough guide.
Q. What if insiders are selling stock—does that always mean trouble?
Ans: Not necessarily. People sell for many personal reasons. But if insiders are selling heavily while the company is doing “well” publicly, that’s worth investigating. It often signals they don’t believe in the long-term story.
Q. Should I avoid companies with complex financials?
Ans: If you can’t explain the financials in plain English, it’s probably a red flag. Complexity can hide problems. Great companies make their numbers understandable, even to outsiders.
