International Stock Investing: Diversified Timing on Country ETFs

In our previous article, we alluded that in a diversified portfolio, putting a long term timing indicator such as 10 month simple moving average on risky assets such as stocks, commodities could effectively reduce risk (i.e. big loss) while improving return. Investors are in a heightened state of anxiety these days as equity markets are consistently at a level where some analysts find them over valued (such as John Hussman's recent analysis or Robert Shiller's Cyclically Adjusted 10 Year PE ratio (Price to Earnings Ratio). Using a long term timing indicator to safe guard these portions of a portfolio is an effective way to do so.

In the international stock asset, investors could utilize today's diverse array of country ETFs to get an exposure. The following is the list of country ETFs used in this strategy:
  • The Netherlands (EWN)
  • Germany (EWG)
  • France (EWQ)
  • Switzerland (EWL)
  • Italy (EWI)
  • United Kingdom (EWU)
  • Belgium (EWK)
  • Austria (EWO)
  • Singapore (EWS)
  • Hong Kong (EWH)
  • Japan (EWJ)
  • Canada (EWC)
  • South Africa (EZA)
The portfolio has equally weighted amount on each country ETF. A 10 month Simple Moving Average (SMA) is used for each ETF. The strategy checks the SMA indicators at the end of each week and does the necessary transactions. Furthermore, the portfolio is rebalanced every year.

The following table illustrates the performance of this portfolio from  5/18/2009 to 12/18/2009.

Users could modify this portfolio to allow addition of recently introduced country ETFs such as emerging or new country ETFs including EWZ (Brazil), FXI (China), INP (India, an ETN or INDY, an ETF). RSX (Russia), TUR (Turkey), THD (Thailand),  South Korea (EWY), PLND (Poland) and VNM (Vietnam), or even regional ETFs such as EPP (pacific), AFK (Africa), GAF (Africa and Middle East), VGK or IEV (Europe).  Moreover, users could change the country weights. It is very encouraging to see that there are some many country ETFs available for investors to get a diversified exposure. Certainly cautions should be taken for those with very little liquidity.

John Hussman Commentary on 12/14/2009: Decidedly Speculative

John Hussman's weekly comment on 12/14/2009: Any virtue of stocks here is decidedly speculative. Stocks are overvalued to a level from which uninspiring returns have always followed. That fact is true regardless of whether or not the economy is in a sustainable recovery. More detailed here. Hussman has been negative since September this year. Recently, however, he has adopted a slight speculative stance on US stock market through call option exposure. Based on his commentary and our estimate here, the stock exposure beta of Hussman Strategic Growth Fund HSGFX is less than 10%. The following are some key points from his above commentary.
  • S&P historical return: Using Barsky-Delong model, to achieve annual real return of 4.2%, the S&P would need to be at 810. Or putting it the other way, Hussman stated that "the conclusion is not that stocks must decline immediately, but rather, that long-term total returns for the S&P 500 are likely to be less than 4.2% after inflation." "Alternatively, on the assumption that future growth rates match what we've observed over the past two decades and indeed over most of the past century, an expected long-term total return of 10% for the S&P 500 (what investors generally carry in their heads as the 'typical'long-term return on stocks) would currently be consistent with an index level of 672".
  • 'Second wave' concerns begin to appear: Hussman has been warning that the second wave of housing credit crunching (the mortgage reset) is approaching the peak at this moment. He quoted Meredith Whitney's interview on CNBC which was very negative on the outlook of 2010: "which is so disturbing on so many levels to have so many Americans be kicked out of the financial system, and the consequence both political and economic of that is a real issue you can't get around. It's never happened before in this country or in the modern economy. The biggest trend in 2010 will be seeing who gets kicked out of the banking system."
So the question is whether the banks could withstand the upcoming credit loss, even with their newly raised equity from public markets this year. Furthermore, with the bailout in effect, how much the banks could shift the loss to the government, i.e. tax payers. Based on the 'stealth stimulus' theory reported by Wall Street Journal, consumers are foreclosing homes and freeing their cash flow to 'stimulate' the economy. Thus consumers -> banks -> taxpayers flow will do a 'stealth' wealth redistribution with 'banks' being intact!

Any way you put it, we are definitely at a situation with many potential landmines. The best approach at this moment is to rebalance your portfolio's asset allocation back to a risk level you could tolerate (remember 2008?) and then stick to the strategies/plans you have chosen.

Core Satellite Portfolios: A Sound and Proven Method to Achieve Reasonable Return with Managed Risk

The concept of core satellite portfolio construction has been adopted for several years by many investment and wealth managers. The EDHEC has collected several papers detailing this concept. ValidFi has maintained a so called Simple Core Satellite Portoflios strategy to show case this concept. In this article, we will discuss the effectiveness of combining simple timing and passive allocation to achieve better risk adjusted returns.

The key idea behind the core satellite portfolios is that, while the traditional passive (buy and hold) strategic asset allocation is suited for long term investment, the short term or intermediate term risk is too much for an ordinary investor to bear with. A portfolio with over 20% peak to trough drawdown (i.e. loss) is probably the maximum for many investors. On the other hand, an actively managed portfolio, while reducing short term risks, could suffer from a stream of short term loss. For example, a moving average based equity portfolio buys into the stock market when the stock market index such as S&P 500 index SPY rises above its 200 days moving average and sells out of the market when the index drops below the 200 days moving average. This strategy works well to protect capital during severe market downturns such as 2008's but it could suffer from loss when markets whip saw in a side way fashion. Furthermore, it could forgo a significant portion of profits when markets rise from depressed low levels. The following table illustrates correlations between the two strategies:


Early Bull
Late Bull
Bear
Side Way
Passive Buy and Hold
Good
Good
Bad
OK
Moving Average Timing
Miss
Good
Good
Bad

Apparently, these two strategies complement to each other in various market or economic cycles. Furthermore, both strategies have exhibited good long term average returns. Combining these two strategies in a portfolio should be able to maintain the long term return while reducing the risk or smoothing out the return curve.

We employed ValidFi's portfolio tool to construct core satellite portfolios based on the above two strategies. The following are three such portfolios that ValidFi now lively monitors.


Buy and Hold Equity
Fixed Income (Total Bond Market Index)
200 Days Simple Moving Average Equity (Satellite)
75% Stocks and 25% Bonds Buy and Hold
75%
25%
0%
30% Stocks and 40% Bonds and 30% Satellite Timing Equity
30%
40%
30%
25% Stocks and 25% Bonds and 50% Satellite Timing Equity
25%
25%
50%

The first two columns combined represent the core part of a portfolio and the last column represents the satellite (actively managed) part of a portfolio. For the stock investment, Vanguard 500 index VFINX (ETF equivalent SPY) is used and for the fixed income part, Vanguard Totoal Bond Market Index VBMFX (ETF equivalent AGG) is used.

The following table shows the characteristics of the portfolios from a period 6/30/1988 to 12/7/2009.

It is evident that core satellite portfolios not only enhanced returns (from 0.7% to 1.3% annually) but also reduced the maximum drawdown (risk) dramatically. The buy and hold portfolio had gut wrenching 42% maximum drawdown which, we suspect, very few investors had stomachs to tolerate. 

The above is a simple example to utilize ValidFi's portfolio platform to construct, study and monitor composite portfolios. For investors who desire to have more diversification over various assets and strategies, such a platform could be handy.
