Piotroski F-Score — fundamental momentum — Joseph Piotroski, University of Chicago, 2000, in a study of whether accounting signals could improve returns among cheap stocks.

Nine yes-or-no tests across profitability, leverage and operating efficiency. Each pass scores one. It asks a narrow question: is this business getting better or worse on its own terms, year over year?

Profitability (4 tests)

Positive profit, positive operating cash, improving return on assets, and cash exceeding profit. The last is the quality test — profit that outruns cash is the one to question.

Leverage and liquidity (3 tests)

Falling debt, improving current ratio, no new shares issued. Growth funded by dilution scores zero here.

Operating efficiency (2 tests)

Improving margin and improving asset turnover.

How to read it7 or more suggests improving fundamentals; 3 or fewer suggests deterioration. It measures direction, not quality — a weak company improving can score higher than a strong one holding steady.

Where it failsA single year of comparison, so one unusual year distorts it. Says nothing about valuation, competitive position or management. Piotroski designed it to rank already-cheap stocks, not to judge a company in isolation.

DuPont decomposition — Devised inside the DuPont Corporation in the 1920s and still the standard way to read a return on equity.

Splits return on equity into its three sources, so the same headline number can be traced to very different businesses.

Net margin

What the company keeps from each rupee of sales. High margin points to pricing power or a genuine cost advantage.

Asset turnover

Sales generated per rupee of assets. High turnover points to efficiency — a retailer earns this way, a utility never will.

Leverage (equity multiplier)

Assets divided by equity. This multiplies whatever the first two produce, in both directions.

How to read itA 20% ROE built on margin and turnover is a different proposition from a 20% ROE built on 3× leverage. The first survives a downturn; the second amplifies it.

Where it failsA single year. Negative equity makes it meaningless. Leverage is structural for lenders, so the third term carries no signal there.

Return on invested capital, and incremental ROIC — Standard in corporate finance; the incremental form was popularised by Michael Mauboussin as the test of whether growth creates value.

ROIC measures what the business earns on all the capital it employs — equity plus debt, less cash. Incremental ROIC asks a sharper question: what has it earned on the money put in since a chosen year?

NOPAT

Operating profit after a notional tax charge, so the figure is independent of how the company is financed. We use 25%.

Invested capital

Equity plus borrowings less cash — the money actually at work.

Incremental ROIC

Change in NOPAT divided by change in invested capital. If it sits below the cost of capital, growth is destroying value however fast revenue rises.

How to read itROIC comfortably above the cost of capital — call it 11–13% in India — means growth compounds. Below it, growth consumes. Incremental below headline means recent investment is earning less than the legacy business.

Where it failsDistorted in the year of a large acquisition. Understated for companies mid-build, where capital is deployed but capacity has not yet been commissioned — an incubator will look poor until it does not.

The earnings quality ladder — Not a named model — the standard sequence an analyst walks when testing whether reported profit is real.

Three ratios read in order, each stricter than the last.

Cash ÷ EBITDA

Does operating profit arrive as cash? Below 0.8 points to working capital absorbing it.

Cash ÷ profit

Does bottom-line profit arrive as cash? Below 1.0 persistently is the classic warning.

Free cash ÷ profit

Does anything survive capex? This is where capital-hungry businesses reveal themselves — a company can pass the first two and still never generate spendable cash.

How to read itRead downward. Each rung failing where the one above passed tells you exactly where the cash is going.

Where it failsA single year of heavy capex depresses the third rung legitimately. Judge it across a cycle.

Reverse DCF — the growth already in the price — A standard inversion of discounted cash flow, used to avoid the forecasting problem entirely.

Instead of forecasting cash flows and deriving a value, it takes today's market value as given and solves for the growth rate that would justify it. The output is not a view — it is the arithmetic of what the market is currently assuming.

Discount rate

The return required for the risk taken. We use 11.5%, roughly the long-run cost of equity in India.

Terminal growth

Growth beyond the explicit ten years. We use 4%, near long-run nominal GDP.

The output

The free-cash-flow growth rate, every year for a decade, that makes the discounted total equal today's market value.

How to read itCompare it with what the business has actually delivered. A price implying 30% a year against a decade of 15% is a demanding assumption; the reverse is a modest one.

Where it failsUseless when free cash flow is negative or unusually depressed, which is common mid-capex. Highly sensitive to the discount rate — a point either way moves the answer materially.

Cost of debt — Interest expense over average borrowings — the effective rate the company actually pays.

What the lenders charge, which is a market verdict on credit quality that no rating agency delay affects.

Well below the policy rate

Suggests interest is being capitalised into assets rather than expensed, or that funding comes from related parties on non-market terms.

Near the policy rate plus a normal spread

Ordinary bank funding. Nothing to explain.

Well above

Lenders are pricing risk the equity market may not yet be.

How to read itAgainst a policy rate near 6%, most sound Indian corporates borrow between 7% and 10%. Read the direction over years as much as the level.

Where it failsUnderstated where a large share of interest is capitalised into projects under construction. Not meaningful for lenders, where interest is cost of goods.
