How to Spot Fake Free Cash Flow (FCF)

Free Cash Flow can look strong even when the business is weak. Use these quick filters:

1. CFO vs Net Profit

CFO should move with profit. If profit rises but CFO stays low → red flag.

Long-term check: CFO / Net Profit > 1.

2. Working Capital Tricks

Companies can boost the CFO by delaying payments, cutting inventory, or collecting aggressively. Watch for sudden jumps in payables, drops in inventory, or odd receivables trends.

3. Capex Reality

FCF = CFO − Capex.

Very low capex in asset-heavy firms is suspicious. If depreciation > capex for many years → investigate.

4. Stock-Based Compensation

Non-cash, but dilutes shareholders.

Real FCF = Reported FCF − Stock Comp.

5. One-Time Asset Sales

Selling land or subsidiaries can temporarily inflate the CFO temporarily. Check for one-time gains.

6. Acquisition Distortion

Acquisitions can bring short-term cash and hide weak organic growth.

7. FCF Margin

FCF Margin = FCF / Revenue.

Healthy businesses show stable or improving margins.

8. Multi-Year Test (Most Important)

Don’t judge in one year. Check 5–10 year trends in CFO, FCF, revenue, and debt. Fake cash flow always breaks over time.
