"Earnings Are Opinion, Cash Is Fact"
Companies have a lot of flexibility in how they report earnings — depreciation schedules, revenue recognition, write-offs. Cash, however, is hard to fake. Either it's in the bank or it isn't.
A company can report record profit and still go bankrupt. It happens more often than you'd think — see Enron, WorldCom, and many others. The cash flow statement is the lie detector.
The Three Sections
1. Operating Activities (the engine)
Cash from running the business. Starts with net income, then adjusts for non-cash items (depreciation) and working capital changes.
This number should be positive and growing. If a "profitable" company has negative operating cash flow, something is off.
2. Investing Activities (the seeds)
Cash going into long-term investments — new factories, equipment, acquisitions. Usually negative for healthy growing companies (they're investing in the future).
The biggest item here is usually CapEx (Capital Expenditures).
3. Financing Activities (the wallet)
Cash flowing to/from shareholders and lenders:
- Issuing stock = +cash, but dilutes existing shareholders
- Buying back stock = -cash, but increases EPS
- Issuing/repaying debt = +/- cash
- Paying dividends = -cash
Free Cash Flow — The King
Free Cash Flow = Operating Cash Flow - CapEx
This is the cash a company actually has left after maintaining and growing its business. It's what funds dividends, buybacks, and acquisitions — and it's often a better indicator of value than reported earnings.
A company trading at 15× free cash flow is roughly the price of paying $15 today for $1 of cash next year (and growing).
The Quality of Earnings Test
Compare net income to operating cash flow over several years:
- OCF consistently > Net Income → high-quality earnings, conservative accounting
- OCF consistently < Net Income → earnings may be inflated; investigate before buying
Red Flags
- Operating cash flow declining while earnings rise
- Free cash flow that's been negative for years with no clear path to profit
- A company funding dividends with new debt instead of cash flow
- Big swings driven by one-time asset sales
Master investors like Warren Buffett start with the cash flow statement, not the income statement. Build the same habit, and you'll spot trouble before the headlines do.
