Stocks and the US$: Correlation Update

Tuesday, March 23rd, 2010
 

First lets review the formula. 

A correlation between two variables is the covariance between each divided by the product of each variables standard deviation (or the square root of each variables variance).

Since the correlation is a normalized number it is important to remember that it is a user friendly but not that usable variable. It describes the co-movement but says little more than that. There are much more powerful analytical co-dependence functions than correlation. Product advertisement: we are thinking about developing a powerful yet fun to use platform that will facilitate statistical modelling of financial markets.

Anyways, look at the recent rolling correlation of the S&P 500 and the US dollar.  This is a rolling 1 year correlation using weekly percent return figures on SPX and DXY.

S&P 500 and DXY Correlation: (Weekly, 1 year)

  1. Notice the very positive correlation leading up to the Tech bubble market peak in early 2000, where the correlation was as high as 60%.  Here the US economy was booming, the stock market was in a dizzying rally, and the US$ continued to strengthen (the EUR was at $0.85 in 2000, versus $1.35 now).
  2. The average correlation in this period was -20% as a strong dollar usually meant bad news for the US economy as it hurt exports, and correspondingly the market. Leading up to August 2008, the equity market was correcting and the equity market was selling off until September when Lehman went broke, and there was a massive flight to quality and the US$ rallied. This threw the market’s negative correlation back to nearly all time low of -60% until …
  3. From less correlated to slightly less correlated.  The correlation is increasing. We had a substantial bottom in the Dollar in December 2009 (since then the DXY is up nearly 8% and SPX is up about 6%).

It is important to mention that though the trade weighted Dollar is up 8% since early December, it is up almost 11% versus the EUR. This implies that versus other currencies the USD has not gained much.

Greece, the Euro, and the European Union

Wednesday, February 17th, 2010

The EUR/USD remains stuck in a downward trend. The Euro has had a tumultuous two years.  After peaking at nearly $1.60 in the summer of 2008, it then plummeted 20% in a little less than 3 months as the financial crisis gripped the EU and it became clear that Europe’s banking sector was under considerable duress. As the market rally unfolded in early 2009, the EUR staged a rally up to $1.50, and has since been hijacked by the Greek drama and sold off to $1.36.

The fragility of the financial system
Given that Greece’s GDP is approximately US$ 356 billion (compared with Germany’s US$ 3,652 billion economy), the Greek debt crisis is not an insurmountable task for the EU.  In fact, current talk is to help Greece meet its immediate obligations (20 billion EUR of its debt falls due in April and May) only. What the Greek crisis has shown the market is the fragility of the global financial system (much like the Dubai scare did in November of last year).  Also clear are the deflationary pressures still circling through the global economy.

Further profligacy is feared
Clearly, either Germany or the EU can gather enough financial resources to bail out Greece. Most likely it will be  a joint effort led by France and Germany, the country with the deepest pockets.  But as the Economist said: “Berlin frets that a rescue will only encourage further profligacy”.

Why the markets got spooked
What is most at question now is the “common currency regime” of the Euro bloc.  Combine the moral hazard problem of bailing Greece out, with bleak finances in the peripheral euro area, the small chance that the Euro bloc countries can maintain their fiscal responsibilities, along with the continuing economic contraction in Europe and you will understand why markets got spooked.

Where do we go from here?
After vague promises, markets want European finance ministers to come up with concrete measures.  The issue at hand is whether the EU will finalize the details of support extended to Greece to prevent a default.  Since January 22, markets have been seized by the ongoing concerns regarding Greek public finances though the S&P rallied back to 1,100 from a low of 1,040.  Let’s put this in a global context:

  • As we discussed on our blog post on January 26 ( click here to read ), Greece’s problems relate not only to an extraordinarily high debt load but a really ugly deficit problem as well: the debt to GDP ratio in Greece is near 125% and the fiscal deficit as a percent of GDP is near 12.5%.
  • The ECB has not done as much as the Fed in reflating its economy: since 2008 M2 has expanded about 13% in the US, whereas in Europe M3 has expanded only 6%.  Additionally the Federal Reserve’s balance sheet has grown by a multiple of 2.6x in the same time frame, compared with 1.4x in the Eurozone.
  • Euro area authorities will find a way to bail out Greece and avoid the markets forcing the PIGS into a default scenario. PIGS refers to Portugal, Ireland, Greece and Spain.  Note that since last week Greek rates have dropped from 7% to 6%.

In summary
We think evaluating the EUR move over the past two months has been fundamentally logical (the EUR is overvalued on a purchasing parity basis, combined with the Greek drama) as well as on a technical basis (DXY seemed to make a major market bottom this year).  We think the EUR will drift lower versus the US$.

Good trading,

Gold: Dont Expect Substantial Weakness

Wednesday, January 6th, 2010

It looked as if Gold had gotten way too ahead of itself.  As you can see on the chart below, Gold surged to over 25% higher than its 200 day moving avergae.  It subsequently sold off about 10% to the 1,100 level. If you look at the past surge ahead of the 200 day (one was 37% and the other was about 30%) there seemed to be a sharp technical selloff combined with “base-building” for the next rally.

Gold and the 200 day moving average

We would bet though that this is not the time to expect a selloff on par with these previous technical related selloffs. In addition note that the last major selloff in Gold was from early 2008 to end of 2008 which of course coincided with the financial crisis, the stronger US$ and therefore weaker commodity prices across the board.  A quote from Marc Faber provides an interesting take on Gold for the next 6-12 months:

“A company’s stock could be less expensive at 100 dollars than when it was selling for 10 dollars, because earnings growth has outpaced the appreciation of the shares and therefore its price/earnings ratio has declined. So gold could be cheaper at the current price than when it was at less than 300 USD because of the explosion of foreign exchange reserves in the world, zero interest rates, the huge debt overhang, and the expectation of further money printing.”

Don’t get us wrong. Gold was one of the best performing global assets in the 2000s decade, and its unlikely it will carry forward with that leading performance. But for right now we see Gold trading much higher.

Positives for the Euro Bloc

Tuesday, December 22nd, 2009

A weakening EUR (versus the US$) is a breath of fresh air for the Euro bloc.  What I think was the catalyst for this selloff in the Euro was the downgrade of Greece.  The Federal Reserve seems likely to raise rates before the ECB and the futures markets are pricing in this probability.  Market talk of the PIGS (Portugal, Italy, Greece and Spain) suggests continued economic weakness. For all the talk of the US as the epicenter, it is important to acknowledge the unique set of problems plaguing the EU. 

The German bond market has performed comparatively well: up 2.9% (through 12/22) year to date, versus -3.0% for the US bond market.  Stock market reaction is a bit mixed: German stocks are up 22.0%, French stocks are up 27.1%, and Italian stocks are up 21.4% – this compares with up 26.9% for US stocks.

Purchasing power parity for the EUR still suggests it is expensive: the PPP estimate provided by Bloomberg is $1.12. Based on current spot rates this implies an overvaluation of 21%. At current spot rate of $1.4274 it is approaching the 200 day moving average ($1.4193) it will be interesting to see if this support level is broken to the downside. If that is the case, the next support level is near $1.30.

US$ Rally Mostly Against EUR, GBP

Tuesday, December 15th, 2009

The EUR is trading at $1.45 for the first time since September (when it broke to the upside, going as high as $1.513). If the EUR heads to the 200-day moving average, it would reach a level in the low $1.40s. It broke below the 50-day moving average earlier in December, which is important given that since the EUR bull move began in March, this has served as a great support level. There are plenty of reasons for the EUR weakness, including Greek CDS spreads continuing their break out. From the Big Picture:

“Greek bonds are down sharply again with their 10 yr yield rising 24 bps to 5.70%, up 83 bps in 2 weeks and at the highest level since April and their 5 yr CDS is at the highest since March due to the lack of faith in the plan laid out by Greece’s PM.”

DXY (US Dollar Trade Weighted Index) has made a notable strong move, its first since January of this year. Its current reading is 77.06.
