FX YTD Performance

Since I was playing around with YTD performance I thought I would isolate a handful of currency pairs and see how they did and as you can see from below they are a mixed bunch.


Variations in performance are generally by themselves not that interesting, after all its a market and it depends upon variation for its survival. However, when we get performance data like this we can have a little bit of a look at correlations and link relative performance to correlation. In the table below I have coloured those correlations at +90% or above blue and those at -90%  or above red.


As you would expect pairs that have a high positive price correlation also have a high performance correlation. Once we get past the positive correlations my eye is always drawn to the negative correlations. For example EURUSD and USDCAD have almost inverse performance and share a -94% correlation. One goes up the other goes down. The mistake traders often make when they see this sort of thing is to assume that a negative correlation is no correlation when in fact these two instruments are very highly correlated. It just happens that the correlation is negative. Instruments that are not correlated have a correlation approaching 0% such as GBPUSD/EURCAD at -0.2% and EURJPY/EURCAD at 1%. This means that they share a very weak or almost non existent relationship.

Correlations are interesting from an academic perspective but there is a little bit of a problem. It is often assumed that correlations are fixed and whilst they can have a degree of stability over time this is a false assumption. The second problem is their relevance to traders who just take signals as they occur and here their relevance tails off. Granted if you are prudent in your exposure to a given currency then you will find yourself cut off from pursuing certain trades. For example if you had been long EURUSD, AUDUSD and GBPUSD at the same time then you dont have three positions but rather one. This sort of dilemma is something each trader needs to manage within their own trading universe as I dont think there is a hard and fast rule that applies to everyone.


YTD Performance

As we sail past the half way point of the year I thought I look in the rear view mirror might be interesting to see how a few select markets have performed. There are no prizes for guessing that the local market has been shit.



FX Correlations

A question popped up in the Mentor Program that related to what to do when related instruments all gave the same signal, in this instance the culprit was various JPY related pairs. I had not looked at FX correlations for awhile so thought I might stick a few together and see if they told me much of a story. With a bit of dodgy-fu I cobbled together the following table which looks at correlations of JPY related pairs over 1 day, 1 week and 1 month.


When looking at correlation we are confronted with two confounding issues. The first, as is obvious from the table above is the time frame over which we look. The shorter the time frame the more we might be prone to simple idiosyncratic shocks appearing in the data. This goes some way to explaining the wild variation i correlations over very sort time frames. As with all things the more data we have the more reliable (sometimes) the conclusions we can draw from what we see.

The second issue is what sort of correlation are we looking at. The correlations above are simple price correlations – do the pairs travel in the same direction over the same time frame. A slightly more sophisticated question question is are the returns from each instrument over various time frames comparable. To answer this question requires that we look at the returns correlations of instruments. The chart below looks at the returns of JPY denominated pairs over a longer time frame.

As broad population they each follow a similar trajectory but there are some notable deviations which can probably be attributed to local factors. One of the issues that often catches FX traders is the assumption that because pairs share a currency then their movement should be identical and as we can see this is not quite true. This causes problems for what signals to take and the entire notion of diversification. Diversification is in its simplest form as practiced by the sell side of the industry revolves around things having different names but even things with similar names can be quite different.

BREXIT – Hard Exit

Apparently this is what a hard exit looks like.

The Year That Was.

It is that time of the year when everyone involved in this business looks in the rear vision mirror and attempts to make sense of what happened.  And of course to everyone involved everything is so obvious and predictable. What is worse is that they take this data and attempt to make some form of prediction about the year ahead. Hindsight is all we have and whilst it is the perfect investment tool; we are denied its luxury in the real world. Even looking at a league table of performance of various instruments is somewhat meaningless. However, since they are all the rage below is one such table I quickly knocked up for a few common instruments.

League Table

Part of the problem is that these tables are looked at from the perspective of the buy and hold investor. It is assumed that you simply bought one of everything last year and held onto it and your performance either good or bad is a function of this. However, this is not how trading works. For example the AUD/USD began the year with a 15% gain, which is then gave back and settled into a meandering decline resulting in its ordinary year on year performance. Likewise all the gain in heating oil came in the first half of the year. Conversely, cocoa which turned in a shocker traded in a range for most of the year and then collapsed in October.

Whilst it is twee to say so in trading only the journey counts not the destination, in fact I would go a little bit further and say that even the starting point is irrelevant. As such tables such as the one above whilst vaguely interesting are essentially irrelevant to us.

It has been sometime since we have had any longvetiy in commodity trends.
