Divides P/E by the annualized EPS growth rate (in percent points). Below 1.0 is conventionally read as 'cheap relative to growth.' Sensitive to which growth window you use; can flip sign if earnings are negative.

Adds dividend yield to the growth denominator so mature dividend payers don't get unfairly punished by a low-growth PEG. Sweet spot ~1.0; below 0.5 is often a broken growth assumption, above 2 is over-paying.

Lower is better for shareholder cash returns; very low values can flag under-investment in a capital-intensive business. Pairs with FCF margin to separate 'thin operating margin' from 'fat operating margin offset by heavy capex'.

Easier to compare than operating_margin across firms with very different leverage / depreciation profiles. Software platforms commonly run above 30%; capital-light service businesses cluster around 20%.

Joel Greenblatt's reformulation of return-on-capital that excludes goodwill, acquired intangibles, and financial assets, focusing instead on the tangible operating capital that actually generates EBIT. Pairs with Greenblatt's Earnings Yield (EBIT/EV) to produce the Magic Formula rank.

First-line profitability measure - how much revenue is left after the direct cost of producing it. Stable gross margin suggests pricing power and low input-cost exposure.

Operating margin minus interest, tax, and below-the-line items. Useful but noisy because tax rate and debt service distort year-to-year comparability.

Captures the leverage between revenue and operating profit. Core test of whether a business converts sales into income at the operating level.

Capital-efficiency measure that ignores how the assets are financed. Useful for comparing within a sector but biased low for asset-heavy businesses (banks, utilities) and high for asset-light ones.

Headline profitability metric. High ROE compounds book value if the business can reinvest at the same return. Beware of buybacks artificially inflating ROE by shrinking the denominator.

Bottom-line growth on a per-share basis, capturing both operating progress and any net buyback effect. The denominator uses absolute prior EPS so a turnaround from negative to positive earnings reads with the conventional sign.

Strips out receivables and inventory, leaving only cash and equivalents over current liabilities. Stress-tests whether the business can meet obligations even if collections seize up.

The acid-test variant of current ratio strips inventory from current assets, since inventory can be stale or written down before it becomes cash. Sweet spot 1.2x; below 0.5x signals liquidity stress, above 3x signals trapped working capital.

The single best operations-quality metric. Negative CCC means the firm is funded by suppliers (Apple, Costco). Long CCC ties up working capital and forces operating-loan dependence.

Earnings-quality flag. Receivables growing faster than revenue is one of the cleanest tells for revenue recognition stretching. Beneish-style.

Five-factor distress signal originally calibrated for US public manufacturers. Above 3.0 is the conventional 'safe' zone, 1.8-3.0 is the grey zone, below 1.8 historically associates with elevated bankruptcy risk.

Beneish (1999) calibrates eight financial-statement indices against a sample of known manipulators. M < -2.22 reads as unlikely manipulator; M >= -1.78 as likely manipulator; the gap is grey. Companion to Altman Z but for fraud risk rather than bankruptcy.

Richard Sloan's accruals-quality measure. Persistent positive accruals (NI exceeds OCF) tend to mean-revert via earnings disappointments. Large negative values are usually fine but can flag one-time working-capital releases or non-cash drags. Phase D-2 made this a target-window metric centred at zero.

Buys oversold pullbacks within an established uptrend (price above the 200-day SMA). Holds while RSI(2) is below an exit threshold; exits when RSI(2) crosses above 60.

+1 when price is above regime_ma and RSI(2) drops below oversold; held while inside the trade; back to 0 when RSI(2) crosses above exit.

+1 = pullback-buy state active, 0 = flat. Bear-side variant uses the symmetric short rule.

Compares price pivots against the MACD histogram (MACD line minus signal line) at those same bars. Bullish divergence: price lower-low, histogram higher-low. Bearish divergence: price higher-high, histogram lower-high.

+1 at right-hand pivot of bullish divergence; -1 at right-hand pivot of bearish divergence; 0 otherwise.

+1 = bullish divergence, -1 = bearish divergence.

Fires on the bar where the MACD line (EMA12-EMA26) crosses through the signal line (EMA9 of MACD). Bullish when MACD crosses up through signal, bearish when it crosses down. Far more commonly used as a trade trigger than divergence (see macd_divergence for the slower confirmatory tell).

+1 on bullish cross (MACD crosses up through signal); -1 on bearish cross (MACD crosses down through signal); 0 otherwise.

+1 = bullish MACD-signal cross, -1 = bearish MACD-signal cross.

When price prints a lower low while RSI prints a higher low at those same bars, momentum is improving even though price is still falling - a classic bullish divergence. The bearish mirror fires when price makes a higher high but RSI prints a lower high.

+1 at the right-hand pivot of a (lower-low price, higher-low RSI) pair; -1 at the right-hand pivot of a (higher-high price, lower-high RSI) pair; 0 otherwise.

+1 = bullish divergence, -1 = bearish divergence, 0 = no divergence at this bar.

Bullish when %K crosses above %D while both lines are below the oversold threshold; bearish when %K crosses below %D while both are above overbought.

+1 on bullish cross in oversold; -1 on bearish cross in overbought; 0 otherwise.

+1 = oversold bullish cross, -1 = overbought bearish cross.
