## Where it is

ScreenRisk tab, Market link and DiversificationAdvanced

The Risk tab, in Advanced: Market link (Correlation and R squared against the primary benchmark) and Diversification (this strategy, its benchmark and each Compare pick; a track on a phone, a matrix on a wider screen).

Index in this video: [Allcap](/strategies/allcap) (strategy page).

## What it means

Correlation runs from -1 to 1. Near 1 the weekly returns rose and fell together, near 0 there was little link, and below 0 they tended to move opposite ways. R squared is correlation squared: the share of the strategy's weekly swings that line up with the benchmark's. The Diversification card works each pair out on the weeks both lines have and needs 26 common weeks; it calls a link weak under 0.3, moderate to 0.8 and strong from 0.8, either sign.

## The formula

Pearson correlation of weekly returns, on the weeks both lines share; R squared is its square.

As computed in the RupeeCase app`Correlation = covariance of weekly returns / (sd x sd), common weeks only
R squared = correlation x correlation
Diversification: each pair needs 26 common weeks, else n/a
Strength by size: under 0.3 weak, 0.3 to 0.8 moderate, 0.8 and above strong`

## Worked example

Example only

* Correlation 0.6 with NIFTY 50
* R squared 0.6 x 0.6 = 0.36
* About a third of the weekly swings line up with the index

## How to read it

* High correlation with your other picks: they tended to move together.
* A negative correlation is not a loss: the two tended to move opposite ways.
* Add an index, fund or strategy with Compare to see it in the card.

## Watch out

* Correlation says nothing about size: a line can be highly correlated and still move less.
* It describes past weeks; links between markets change over time.
* This recording reads month end history, so its pairs are months.
