LIX FAQ — ONELIX risk score and indicators

FAQ from all LIX universe guides: LIX score, methodology, VIX, yield curve, CAPE, credit spreads, and more. Search and filter by topic. Educational content — not investment advice.

Can a risk indicator predict a crash?Market risk

No. It helps contextualize a market environment, but it cannot predict the timing or magnitude of a correction on its own.

Why use several indicators?Market risk

Because each indicator observes a different dimension: valuation, rates, credit, economic cycle or volatility. Combining them reduces the risk of relying on one isolated signal.

What is the LIX score for?Market risk

The LIX score summarizes several indicator families into a normalized reading so the risk context can be compared more consistently over time.

Can the LIX also highlight statistical opportunities?Market risk

Yes, to contextualize historically more favorable zones (less frequent drawdowns, sometimes higher average returns over 24 months). This is not a buy signal or a guarantee of future performance.

What is the difference between crash, bear market and correction?Market risk

A correction is roughly a 10% decline; a bear market, at least 20% on a major index; crash often means a major correction. ONELIX tracks 15 episodes of 19% or more since 1962.

Does a low LIX signal a bull run?Market risk

No. A LIX in the SEREIN zone indicates a statistically less stretched context, but bull runs can last for years. A rising LIX from a low zone can also signal the end of euphoria — cross-check with underlying indicators.

What does the LIX measure?LIX score

The LIX (Lucid Index) is a proprietary composite score aggregating 12 normalized indicators to synthesize a vigilance level on market orientation, on a 0–100% scale.

Does the LIX predict crashes?LIX score

No. It contextualizes statistical and historical risk, without a correction calendar.

How should a high LIX be interpreted?LIX score

According to historical data, several indicator families are tense at the same time; history associates that with more corrections, with no date. It is not a sell signal.

Is it a proprietary indicator?LIX score

Yes. General steps are documented, but weights, temporal smoothing and aggregation parameters remain proprietary.

Should level or trend be prioritized?LIX score

Trend. The LIX is more informative when its direction changes than when it simply reaches an isolated threshold.

Does the LIX signal a favorable context for equities?LIX score

In the SERENE zone, major declines have historically been less frequent and returns higher than in the CRITICAL zone. This is a statistical reading, not a buy signal or performance guarantee.

What does a LIX decline toward a low (SERENE) zone mean?LIX score

Historically, this often accompanies easing market stress — sometimes after a bear market or major correction, when the LIX sits in the SERENE zone. This is not a buy signal or a guaranteed recovery.

What does ONELIX methodology describe?Methodology

It describes indicator selection, normalization, LIX reading, historical statistics and limits.

Do backtests predict the future?Methodology

No. They describe past behavior on historical data.

Why combine several indicators?Methodology

To reduce dependence on a single signal and read several risk dimensions.

What does the Buffett Indicator measure?Buffett indicator

The total stock market capitalization (Wilshire 5000) to nominal GDP ratio, transformed into a 0–100% ONELIX score via an exponential trend and standard deviations.

How is it different from the PE10 (CAPE)?Buffett indicator

Both measure valuation but from different angles. The Buffett Indicator compares market capitalization to GDP (a macroeconomic reference). Robert Shiller's PE10 / CAPE compares price to ten-year smoothed real earnings.

What are the data sources?Buffett indicator

Wilshire 5000 (^FTW5000) for capitalization, nominal GDP from FRED (series GDP), exponential trend and ONELIX proprietary normalization.

Does it predict crashes?Buffett indicator

No. It describes an extreme valuation context and historical detection frequencies, not a market calendar.

Why does the ratio drift higher over time?Buffett indicator

Globalization of earnings, financialization, low rates and sector composition can justify a higher "normal level" than historically.

Can it be used on its own?Buffett indicator

No. It is more useful cross-checked with PE10, Earnings Yield Gap, Margin Debt, credit, rates and volatility.

What does the PE10 / CAPE measure?PE10 / CAPE

The cyclically adjusted price-to-earnings ratio of the S&P 500: real price divided by ten-year average real earnings, using Robert Shiller's data.

Why use ten-year average earnings?PE10 / CAPE

This average reduces the impact of an exceptionally high or low year of profits and captures normal earning capacity through a complete cycle.

What is the difference with the Buffett Indicator?PE10 / CAPE

The PE10 / CAPE compares prices to ten-year real average earnings. The Buffett Indicator compares total stock market capitalization to nominal GDP.

Can the PE10 / CAPE forecast corrections?PE10 / CAPE

No. It contextualizes long-term valuations and expected returns, but it does not predict the timing of corrections on its own.

How does ONELIX turn the PE10 into a 0-100 score?PE10 / CAPE

ONELIX computes rolling standard deviations of CAPE since 1950, then applies a proprietary formula to produce a normalized score integrated into the LIX.

Why can a high PE10 last for a long time?PE10 / CAPE

Low rates, high profit margins or a favorable sector composition can sustain elevated multiples for several years.

What does the Yield Curve measure?Yield curve

The gap between the 10-year Treasury and the 3-month Treasury (10Y-3M spread), normalized to an ONELIX score of 0–100%. A high score signals a flat or inverted curve.

Why the 10Y-3M spread?Yield curve

It is the most widely followed measure of curve inversion and its historical correlation with US recessions since 1969.

Are recession and equity crash synonymous?Yield curve

No. The curve mainly reads the macro cycle. A recession can occur without an immediate equity correction — hence 40% of crashes not detected at the peak.

What are the data sources?Yield curve

10-year Treasury (FRED DGS10), 3-month Treasury (FRED DGS3MO), proprietary ONELIX calculation (z-scores, persistence, 0–100% normalization).

Does it predict crashes?Yield curve

No. It informs on the macro cycle and historical frequencies (27% / 27% / 40%), without equity market timing.

Can it be used alone?Yield curve

No. Cross-check with Interest Rates, high yield spreads, valuation, macro cycle and volatility.

What does the Interest Rates indicator measure?Interest rates

The consistency between real S&P 500 valuation and long-term rates (10-year Treasury), synthesized in an ONELIX score of 0–100%. A high score signals an expensive market in a restrictive rate environment.

What are TINA and TARA?Interest rates
TINA (There Is No Alternative): low rates, equities remain attractive despite high valuation. TARA (There Are Reasonable Alternatives): high rates, bonds become a credible alternative — the riskiest zone for expensive equities.
Why combine valuation and rates?Interest rates

An expensive market does not carry the same risk in every rate environment. The expensive market + high rates combination (1980, 2000, 2007) is historically the most toxic.

What are the data sources?Interest rates

Real S&P 500 (inflation-adjusted, Shiller series), 10-year Treasury (FRED DGS10) and proprietary ONELIX calculation (sum of z-scores, 0–100% normalization).

Does it predict crashes?Interest rates

No. It identifies valuation/rate tension zones and historical detection frequencies (20% / 27% / 47%), without market timing.

Can it be used alone?Interest rates

No. It is more useful cross-checked with the yield curve, high yield spreads, valuation, macro cycle and volatility.

What does the VIX measure?VIX

30-day implied volatility of S&P 500 options, synthesized into an ONELIX score of 0–100% via the monthly median.

How does it differ from Gold Volatility?VIX

The VIX reads short-term equity implied volatility; Gold Volatility reads cross-asset stress via a safe-haven asset.

What are the data sources?VIX

CBOE VIX (FRED VIXCLS), monthly median, proprietary ONELIX normalization.

Why is the VIX low at market peaks?VIX

The VIX is contrarian: a low reading at the top often reflects complacency, not the absence of risk.

Does it predict crashes?VIX

No. It informs on sentiment and the price of protection, without providing a market calendar.

Can it be used alone?VIX

No. It must be cross-checked with credit, valuation, leverage and cross-asset volatility.

What does the Sahm Rule measure?Sahm rule

Deterioration of the US labor market: 3-month moving average of BLS unemployment minus the 12-month low, with a reference threshold of 0.5 percentage point.

Does the Sahm Rule predict stock market crashes?Sahm rule

No. It confirms macroeconomic recession risk; it is not designed as a direct equity timing signal.

What is the standard Sahm Rule threshold?Sahm rule

0.5 percentage point: when the 3-month moving average of unemployment exceeds the 12-month low by 0.5 pp.

Why does it often arrive late?Sahm rule

Unemployment is a lagging indicator: it deteriorates after financial conditions tighten and often after part of the equity correction.

What are the data sources?Sahm rule

Monthly unemployment rate published by the BLS (FRED UNRATE series), public Claudia Sahm rule calculation, proprietary ONELIX normalization.

Can it be used on its own?Sahm rule

No. It should be cross-checked with valuation, rates, credit and volatility for a complete market risk reading.

What do Junk Bond Spreads measure?High yield

The ICE BofA OAS premium between high yield bonds and Treasuries, transformed into an ONELIX score of 0–100% with inverted logic (low spread = high score).

Why inverted logic?High yield

A low spread (complacency) generates a high score at the market peak; a high spread (panic) generates a low score — contrarian reading similar to the VIX.

What are the data sources?High yield

ICE BofA US High Yield Option-Adjusted Spread (FRED BAMLH0A0HYM2), inverted z-scores, proprietary ONELIX normalization.

Why a low spread at the market peak?High yield

Contrarian indicator: a compressed spread at the peak reflects credit complacency (e.g. 2021 at 2.5%), not the absence of risk.

Does it predict crashes?High yield

No. It informs on credit complacency or stress and historical frequencies (63% / 38% / 0%), without market timing.

Can it be used alone?High yield

No. Cross-check with yield curve, Interest Rates, valuation, leverage (Margin Debt) and volatility.

What does the Earnings Yield Gap measure?Earnings yield gap

The gap between the earnings yield on equities (inverse of S&P 500 P/E) and the yield on 10-year Treasury bonds.

Why compare equities to bonds?Earnings yield gap

Bonds represent an alternative source of return. The comparison helps assess whether equities offer sufficient relative compensation in a given rate regime.

Why is the ONELIX logic inverted?Earnings yield gap

A low gap signals that equities are expensive relative to bonds; the model transforms this into a high score (risk), and vice versa for a wide gap.

Can the Earnings Yield Gap forecast corrections?Earnings yield gap

No. It contextualizes the relative valuation of equities versus bonds, but it does not predict the timing of corrections on its own.

How does ONELIX turn the EYG into a 0-100 score?Earnings yield gap

ONELIX computes standard deviations of the gap with inverted logic, then applies a proprietary formula to produce a normalized score integrated into the LIX.

What is the difference with PE10 / CAPE?Earnings yield gap

PE10 / CAPE measures absolute valuation via smoothed earnings; the EYG explicitly incorporates bond yields as an alternative source of return.

What does Margin Debt measure?Margin debt

The total debt borrowed by investors from brokers to buy stocks, read as year-over-year change relative to market capitalization, then normalized into a 0–100% ONELIX score.

Why use a YoY change rather than the raw level?Margin debt

The raw level grows with market size; a dynamic reading relative to capitalization better contextualizes leverage excesses.

What are the data sources?Margin debt

Monthly FINRA data (NYSE / FINRA Margin Debt) since 1960, CPI inflation-adjusted, with market capitalization and proprietary ONELIX normalization.

Does Margin Debt predict crashes?Margin debt

No. It describes speculative euphoria and leverage-related vulnerability, not a market calendar.

How does ONELIX transform Margin Debt?Margin debt

ONELIX computes inflation-adjusted YoY change, relates it to market cap, then transforms it into a 0–100% score via standard deviations and a proprietary formula.

Can it be used on its own?Margin debt

No. It must be cross-checked with valuation, rates, credit and volatility.

What does Gold Volatility measure?Gold volatility

The annualized volatility of gold prices over 20 days, transformed into a proprietary ONELIX score from 0 to 100%. A high score signals systemic stress and flight to quality relative to history.

How is it different from the VIX?Gold volatility

The VIX reflects mostly short-term implied volatility via S&P 500 options. Gold Volatility reads cross-asset tension via a safe-haven asset, sensitive to systemic crises, real rates and the dollar.

What are the data sources?Gold volatility

Prices come from LBMA Gold Price (spot) and the SPDR Gold Shares (GLD) ETF. ONELIX computes 20-day realized volatility, then applies a proprietary transformation with persistence and historical contextualization.

Is it a proprietary indicator?Gold volatility

Yes. The general logic (20-day volatility, 0–100% score) is documented, but detailed model parameters remain proprietary.

Does it predict crashes?Gold volatility

No. It describes a statistical context of systemic stress. Elevated levels have historically accompanied some major corrections, without providing a precise date.

Can it be used on its own?Gold volatility

No. It is more useful cross-checked with VIX, Margin Debt, Big Cap Volatility, credit, valuation and the macro cycle.

What does Big Cap Volatility measure?Large-cap vol.

It measures the instability of the largest capitalizations' relative weight versus the rest of the market. The ONELIX score is a normalized 0–100% version.

How is it different from the VIX?Large-cap vol.

The VIX reads mostly short-term implied volatility via options. Big Cap Volatility reads slower structural fragility linked to mega-cap concentration in the US equity market.

What are the data sources?Large-cap vol.

Capitalization series come from the Kenneth French Data Library (market equity breakpoints). ONELIX then applies a proprietary transformation and percentile normalization.

Is it a proprietary indicator?Large-cap vol.

Yes. The general logic (top 5% vs median concentration, rolling volatility, historical percentile) is documented, but detailed model parameters remain proprietary.

Does it predict crashes?Large-cap vol.

No. It describes a statistical context of structural fragility. Elevated levels have historically increased the frequency of major corrections at 12–24 months, without a precise date.

Can it be used on its own?Large-cap vol.

No. It is more useful when cross-checked with VIX, Margin Debt, Gold Volatility, credit, valuation and macro cycle.

What does S&P Mean Reversion measure?S&P mean reversion

The deviation of the real S&P 500 (inflation-adjusted) from its long-term exponential growth trend.

Why compare the S&P 500 to a long trend?S&P mean reversion

The long-term trend provides a stable historical reference and helps measure the market's extension or normalization phases.

What is the difference with the Buffett Indicator?S&P mean reversion

S&P Mean Reversion measures the deviation of the S&P 500 from its trend. The Buffett Indicator compares total stock market capitalization to nominal GDP.

Can S&P Mean Reversion forecast corrections?S&P mean reversion

No. It measures a deviation from trend, but it does not predict the timing of corrections on its own.

How does ONELIX turn the indicator into a 0-100 score?S&P mean reversion

ONELIX computes standard deviations from the exponential trend, then applies a proprietary formula to produce a normalized score integrated into the LIX.

Why can the indicator stay elevated?S&P mean reversion

A positive deviation can persist if liquidity, rates, expected growth or investor confidence durably support the market.
