Here's how I do a quick reading of cashflow to help me understand more about a stock
Here are all 8 possible combinations of CFO, CFI, and CFF:
CFO+ / CFI− / CFF−
CFO+ / CFI− / CFF+
CFO+ / CFI+ / CFF−
CFO+ / CFI+ / CFF+
CFO− / CFI− / CFF+
CFO− / CFI+ / CFF−
CFO− / CFI+ / CFF+
CFO− / CFI− / CFF−
1. CFO+ / CFI− / CFF− — Mature, self-funding company
Operations generate cash, that cash funds growth/capex, and there's enough left over to pay down debt, buy back shares, or pay dividends. This is the gold standard — a business fully financing itself with no reliance on outside capital. BRC Asia and SIA both fit this pattern: strong operating cash, funding capex/acquisitions internally, still returning cash to shareholders.
2. CFO+ / CFI− / CFF+ — Growth company, externally funded
Operations are healthy, but the company is investing more than operations alone can support, so it raises debt or equity to fund the gap. Classic expansion-stage profile. Keppel DC REIT fits here — growing operating cash from its data centre portfolio, but funding aggressive acquisitions (Tokyo DC 3, land lease extensions) through new units and debt, since REITs must pay out most of their income and can't retain much cash.
3. CFO+ / CFI+ / CFF− — Cash harvesting / capital discipline
Operations are profitable, the company is net divesting (selling assets/investments faster than buying), and using the combined cash to delever or return capital to shareholders. Typical of mature or declining-growth businesses that have moved past their expansion phase and are prioritising capital return over reinvestment. Worth checking whether the divestments are of non-core assets (fine) or productive capacity (a warning sign).
4. CFO+ / CFI+ / CFF+ — Cash stockpiling
Cash is coming in from every direction: operations, asset sales, and new financing. The least common combination, since a company that's already generating and harvesting cash doesn't usually need external capital too. Often signals a business building a war chest for a large anticipated move (acquisition, refinancing at better terms, or a defensive buffer). Always worth asking why raise money if cash is already flowing in from two other sources.
5. CFO− / CFI− / CFF+ — Early-stage / high-growth, cash-burning
Operations aren't yet self-sustaining, the company is investing heavily in future capacity, and it's funding all of it — the operating shortfall plus the investment — through external capital (VC rounds, debt, IPO proceeds). Classic startup or pre-profitability growth company profile. Sustainable only as long as investors keep believing in the growth story; a red flag if it persists for many years without a credible path to positive CFO.
6. CFO− / CFI+ / CFF− — Distressed, selling the furniture
Operations are burning cash, the company is selling off assets to raise cash, and using proceeds to pay down debt rather than reinvest or fund operations. Often a sign of financial distress or restructuring — the business is shrinking, not growing, and management is triaging: sell what you can, pay off what you owe. Worth checking how sustainable this is once the assets run out.
7. CFO− / CFI+ / CFF+ — Deep distress / survival mode
Operations are losing cash, the company is selling assets, and still needing to raise fresh financing on top of that just to stay afloat. This is one of the most concerning combinations — every available lever is being pulled just to keep the lights on. Common in companies heading toward restructuring or bankruptcy, or in severe cyclical downturns (e.g., airlines during COVID lockdowns) where survival, not growth, is the objective.
8. CFO− / CFI− / CFF− — Unsustainable without a cash buffer
Operations are burning cash, the company is still investing (maybe due to committed capex it can't easily cut), and it's also paying down debt or returning capital rather than raising fresh funds. This combination can only be sustained by drawing down existing cash reserves — there's no external cushion being added. It typically shows up briefly in cyclical downturns for companies with strong balance sheets that can afford to ride out a rough patch (e.g., honouring dividend commitments while sales are temporarily depressed), but it's not viable indefinitely without either an operational recovery or new financing.
Quick mental model: CFO tells you if the core business works. CFI tells you if the company is growing or shrinking its asset base. CFF tells you how that gap is being bridged — externally (raising capital) or internally (returning/paying down capital). The healthiest combination is #1; the ones to watch closely are #5 through #8, where operations alone aren't covering the bills.
