What is Free Cash Flow?

A high and growing free cash flow is one of the healthiest signs a company can give: it indicates that the business generates more cash than it needs to sustain itself, which gives it room to reward the shareholder and weather crises without borrowing. A stagnant or declining FCF while sales rise usually warns that the business increasingly needs to reinvest more to grow the same amount, a symptom of loss of efficiency or competitive pressure.

A negative free cash flow is not always bad. In young companies in full expansion it is normal and even desirable: they are investing aggressively in capex to capture a large market, and that spending depresses FCF today in exchange for more cash tomorrow. The key question is whether that investment generates returns: a negative FCF that builds a competitive advantage is very different from one that merely plugs holes. In mature companies, by contrast, a recurring negative FCF is a red flag.

To judge high or low FCF correctly, look at it relative to the size of the company (hence the FCF yield, which divides it by market capitalisation), to its trend over several years and to the quality of its earnings (what percentage of net profit converts into cash). An FCF that grows steadily and represents a solid part of profit is the signature of a robust business; an erratic one, or one much lower than profit, invites you to investigate why.

The difference between free cash flow and net profit is one of the most important in fundamental analysis. Net profit is calculated according to accounting standards and includes items that are not cash movements: depreciation (an expense that does not leave the bank), provisions, revenue accrued but not collected, deferred tax adjustments. FCF eliminates all of that and keeps the money that actually came in and went out, after paying the necessary investments.

That is why a business can declare healthy accounting profits and, at the same time, generate little or no free cash flow. The typical causes are very high capex, working capital that grows endlessly (customers slow to pay, inventory that piles up) or profits inflated by non-cash entries. The comparison between profit and FCF over several years is one of the best detectors of earnings quality: if cash closely follows profit, there is solidity; if it drifts away, you should be wary.

This links with quality analysis, which insists on looking at the real ability to generate cash and not just accounting profit. DeepTicker captures that philosophy in its DeepScore grade: cash generation weighs on the Profitability and Track record dimensions, so a company that converts its profits into FCF consistently scores better than one that only presents profits on paper. You see the reason behind every number, no black boxes.

Free cash flow is the raw material of valuation. The most rigorous method for estimating what a company is worth, the discounted cash flow (DCF), consists of projecting all future free cash flows and bringing them back to present value with a discount rate that reflects risk (the cost of capital or WACC). The value of a company, ultimately, is nothing more than the discounted sum of all the free cash it will generate over its life.

The problem with the classic DCF is that it requires guessing the future: how much will FCF grow each year over the next decade? Small changes in those assumptions send the result soaring or crashing, which makes it very sensitive and easy to manipulate to justify any price. That is why DeepTicker reverses the logic with the Reverse DCF: instead of projecting FCF to derive a value, it starts from the market price and calculates what FCF growth and what cash margin that price is discounting.

This twist on cash flow discounting turns a black box full of assumptions into a concrete, answerable question: "do you really believe this company can grow its free cash flow at 18% a year for ten years?". In addition, DeepTicker does not project flat growth, but moderates it year by year until it approaches the growth of the economy (a multi-phase model with fade), and uses the real cost of capital of each industry. So the judgment about FCF is realistic, not a castle of optimistic numbers.

To see the free cash flow of a stock in DeepTicker, search its ticker or name and open its profile. You will find the operating cash flow, the capex and the resulting FCF, alongside its evolution over several years and the FCF yield that puts it in relation to market capitalisation. Every figure comes explained and broken down, no black boxes: you see where the cash comes from and how much of the accounting profit converts into real money, so you learn to read a company's financial health as you analyse it.

Beyond the figure, DeepTicker uses FCF as the basis of its Reverse DCF to show you what cash expectations the current price incorporates and let you judge whether they are credible. Instead of an opaque verdict, you get a clear label —Bargain, Reasonable, Demanding, Expensive or Discounted bubble— accompanied by the reasoning. It is the rigour professional analysts apply, translated into language anyone can understand.

And with the search tool and the screener you can filter thousands of companies by cash generation —for example, stocks with growing FCF and an attractive FCF yield within a sector— combining it with quality, growth and solvency to locate candidates to analyse in depth. Remember that DeepTicker offers information and analysis so that you decide, never advice: the idea is that you always combine the cash the business generates (is its profit real?) with its valuation and its quality.
