In this thread I hope to find the answers to the following questions:

 

  1. Is it true that GBPUSD and EURUSD are 98% correlated? How has the correlation been calculated? For how long this relationship would last?
  2. How can we relate GBPUSD movements with EURUSD movements? Is ATR a reliable tool?

I'm quite open to any other topic that discusses the relationship between these two pairs. It would be great if you accompany your ideas with links to reliable white papers or news articles.

You might find the following article useful.

The authors beleive that...

"Statistical considerations imply that the GBP is already behaving as a true EUR."

I've not purchased the article yet. It costs $32 and I'm not quite sure if it worths it.

That's right, EURUSD and GBPUSD are correlated STRONG.


Statistically we can say: "the linear association between EURUSD and GBPUSD is SIGNIFICATIVE and almost perfect"

Hi pablorpl,

Thanks for your quick response. Could you explain the calculations a little bit more?

Thanks,

Therefore

The correlations are used on Capital Allocation Pricing Models (CAPM) for "portfolio choice". We hope find NO correlated items for build a risk reduced portfolio.... this is used for stocks market.

I don't see correlations utility in GBPUSD and EURUSD market
pablorpl,

Thanks very much.

pablorpl,

Thanks very much.
You can diversify FX portfolio with items as:


EURUSD, GBPJPY, CHFCAD

or other combinations with low correlation

Thanks very much. What I'm looking for is to benefit from this correlation for example what if you go long on GBPUSD and short on EURUSD at the same time. It is very similar to hedging but my broker pays positive swap on long cable and short Euro so I can benefit from leverage and make money at the same time. I'll detail my approach very soon but it would be a good idea if I hear from you about this.

Thanks

Last Friday was a prime example of how they were moving together pip by pip almost, due to the fact that non-majors were not being traded very heavily with lack of news interest. The result was that mainly the dollar supply was reflected pretty strongly in any USD pair and EUR/GBP for example was pretty much sidelined (moved 10 pips or so in 12 hours).

Note: you can lose money hedging, plain carry trading is a lot better in my humblest of opinions. Good luck.

Plutonite,

Thanks very much for your feedback. I quite understand your concern. I started this experiment on a demo account and in less than 30 days it was 30% up. However, I'm still working on it to make sure it really is a profitable approach.

Good Luck,
Al
i don't think u can totally count on the correlation....
must be careful in placing ur position...
quite a good related pair. almost a contsnt value.
Trading for a living!
Both pairs are very much related.

Almost the same data affects them both
Please note the important difference between Regression and correlation:

1- there is an underlying relationship between comparing two variables in a regression- that is always reliable, and predictable, such as height and weight of an individual as an example.

2- a correlation is used correctly above because it is defined as two variables,
or currencies as having an association or possible connection between each other- remember : this association may only exist for a short or in a medium
time frame.

3- the market is always fluid; it has a personality and that may change over
time, so set up an edge that really works for you, and stick to those signals
and with basic money management- you will arrive ahead of your expectations.

Hope this helps, G.K.

.1 - No, the mostly correlated pair to EURUSD is USDCHF that is inversely correlated at about -85%, GBPUSD is around 60%, and that correlation as been loosening in the last two months. Although we can see some simlutaneous moves on both (and more) pairs, it's wrong to assume that they are highly related.

.2 - Answer to point 1 greatly invalidates any further discussion of possible correlation studies...
