Correction Risk

How it is measured

The estimate combines three stress measures that historically move together around drawdowns: how far the central bank has moved its policy rate over the past twelve months, the extra yield demanded on risky credit, and how many stocks are participating rather than a narrow few. The rate term carries the largest single weight of the three.

Combining them matters because any one can be misleading alone. Volatility spikes on events that resolve in days. Breadth narrows in healthy markets. The estimate rises when several independent measures flash at the same time.

How to read it

A higher reading means more of the underlying measures are stressed simultaneously. It does not mean a correction is imminent, and this distinction is the whole point of the number.

A high reading can persist for months without a correction arriving, and a correction can begin from a low reading. Treat it as a check on your own positioning rather than as a trigger.

A worked example

An elevated reading is best used as a question rather than an instruction. If stress is visibly high and your portfolio is positioned as though it were not, that gap is worth examining. If your positioning already reflects the risk, an elevated reading changes nothing.

The most common mistake

Using it as a market timing tool. Every measure feeding it is coincident or lagging, not leading. The estimate describes the weather now, and dressing for the weather is not the same as predicting it.

How CORVIX uses it

CORVIX publishes the current correction risk figure free on the market regime today page, per region as well as globally, and never silently substitutes a default when the inputs are unavailable. An honest null is preferred to a fabricated all clear.

Common questions

What is Correction Risk?

Correction risk is an estimate of how much stress is currently visible in markets, expressed as a probability. It is a description of present conditions rather than a forecast of what happens next.

How is correction risk measured?

The estimate combines three stress measures that historically move together around drawdowns: how far the central bank has moved its policy rate over the past twelve months, the extra yield demanded on risky credit, and how many stocks are participating rather than a narrow few. Combining them matters because any one can be misleading alone. Rate moves act with a long lag. Credit can widen on supply rather than fear. Breadth narrows in healthy markets too. The estimate rises when several independent measures flash at the same time. Each input is scored against fixed thresholds rather than continuously, so the figure moves in visible steps and small changes in it are not meaningful.
