Correlation Portfolio Diversification

A Macro-Economic Study of Correlation between Tradeable Assets

It can be challenging to visualise the correlation between assets when you have a whole portfolio full of them. You can create a heatmap that shows all the assets in your portfolio and the correlation between them.

And in true Darwinex fashion, we’ve created a heatmap for 40 of the Darwinex platform assets. This heatmap gives us a high-level view of the correlation between this universe of tradeable assets at Darwinex.

It might look like some random NFT, but what this heatmap does is display the correlation between every asset in an easy to see manner. Using a heatmap in this way can help speed up asset selection when deciding on what to put in your portfolio.

Correlation is the enemy of Diversification.

It gives you a clear view of what combinations of assets are likely to provide good diversification benefit and which ones are likely to not. This extra clarity is essential because trading correlated assets can increase the risk on the portfolio.

What is Delta?

Delta is a mathematical term that simply means a change in value. In a previous post, we showed you how to calculate (r) and (R²), but we highlighted a flaw in this approach and showed you how to calculate (R²) using the Delta (the price change) instead, which is a much more robust way to calculate the correlation.

Using the heatmap, we can see the correlation between an FX major like GBPUSD and the FTSE index. Looking at the heatmap, we can quickly see that these have a correlation of 0.00036. This correlation would indicate that trading these two assets at the same time could provide us with diversification benefit.

Take a look at Martyn’s heap map. If you had to pick 2 FX pairs, a stock index and a commodity, what would you choose and why?

As always, answers on a postcard @darwinexchange

This post covers the correlation between assets. But there are three other techniques we’ve used previously. In the next episode, we take a look at the correlation between timeframes.

Benefits of Portfolio Diversification

How to Measure Correlation Between Assets

In the previous episode, we showed you two ways to measure correlation. These were; coefficient of correlation (r) and coefficient of determination (R²). These are two widely used techniques for measuring correlation.

However, they do have their limitations.

When the quote currency in two fx pairs is the same, there will always be a correlation. However, due to the fundamental differences in base currency, they will also display uncorrelated behaviours.

This gives us an incorrect view whereby the (R²) number indicated a high level of correlation but the outlying data points highlighted the uncorrelated nature too. Talk about confusing.

A small change can have a big effect.

Today we’re going to make a subtle change that can provide a more robust view of the correlation between assets.

Instead of using price, we’re going to use the price difference. As an example, if we subtract an assets close price from the previous days’ close price, we can see the price change. It is this change in price that we will use for our new calculation.

Already you should be able to see the benefit of using this way. It allows us to compare price movements between the two assets.

We’ve given you a few examples of how correlation differs between assets and a few examples of different ways to measure correlation.

You can take this one step further by creating a correlation matrix in Excel for an indefinite number of assets.

Try doing the above to measure correlation between all the assets you have in your portfolio and see how diversified your asset selection is.

Darwinex helps you measure correlation of Darwins.

Darwinex has already done the hard work for you on the Darwinex platform by calculating the correlation between Darwins.

Remember a Darwin is an asset that tracks the performance of a traders underlying trading account, in real-time. Darwinex then manages the risk of the Darwin independently from the trader to target a max VaR (95%) of 6.5%.

To view the correlation between Darwins go to the correlation tab. It will show the correlation between the asset you have selected and a range of other Darwins. To check a particular darwin enter its ticker into the search box under the table to see the correlation between them.
