Hi Davidrmoran,
I too am not now a financial advisor client. I did use one in the early
1960s until I realized he had more incentives to churn my portfolio rather than increasing its value.
I recognize my personal experience is not universal, and the financial advisor industry can and does provide useful services for many customers. They educate and hold hands for those with weak stomachs or itchy trigger fingers. To paraphrase a Charlie Munger observation: As a money manager, he has experienced 50% drops 3 times in 50 years. The market is always 2 steps up and
1 step back. If you can't handle the
1 step back you shouldn't be in the market.
I suspect you suffered a dyslectic moment (it happens to me too) in your opening statement: “If you examine correlation history, and not just recent, global markets very often do not provide much diversification.” I remembered the data with just the opposite impact. So I checked to verify.
I used Vanguard as my primary historical data source, and updated their data summary and analysis with work I completed using Portfolio Visualizer.
Here is the Link to the Vanguard study titled “ Considerations for Investing in non-U.S. Equities”:
https://personal.vanguard.com/pdf/icriecr.pdfThe report was released in March, 20
12. It concluded that although correlation coefficients have closed towards a perfect correlation of One value, diversification still mitigates individual investment class volatility and contributes towards end wealth. Vanguard concluded that a 20% to 40% foreign holding equity position had merit. Beyond the 40 % level the law of diminishing returns took hold, and in fact, acted to retard the portfolio.
Correlation coefficients are highly volatile entities. Just observe the noise like signal of the
1-year data and contrast that against the
10-year signal like data, both displayed in the Vanguard
15 page report. The data is given for many foreign Countries. It clearly demonstrates lower correlation coefficients in yesteryear with a definite tendency towards closure recently. In yesteryear, the correlations resided in the 0.4 to 0.6 range; today, those correlations are North of 0.8.
Since the Vanguard data ended a few years ago, I updated it with an analysis I made using the Portfolio Visualizer website source. Here is the Link to the Portfolio Visualizer Asset Correlation toolkit:
http://www.portfoliovisualizer.com/asset-correlationsWhen I said “global market diversification” I meant it in its most general sense to include all categories of asset class options. I updated the Vanguard study by examining the more recent correlation coefficients among the S&P 500 (VFINX), the total Bond market (BND), the FTSE (VEU), Emerging markets (VWO), and REITs (VNQ) as an incomplete set of primary holdings. I did mix mutual funds and ETFs since they reflect my current positions.
I had the Portfolio Visualizer compute correlation coefficients for
1, 3 and 5 years of the most recent data. Results bounced around, reflecting the unstable nature of correlations. The Bond asset retained a negative correlation against the equity holdings. The equity correlations were in the high range, very similar to the quoted Vanguard data sets with one exception. The
1-year Emerging markets correlation with the S&P 500 reverted backward to a 0.66 value.
Sorry for this detailed examination, but I felt your opening statement needed further clarification. Perhaps we are using different definitions for the short-term and the long-term. Timeframe disparities cause investment misunderstanding and need careful definition. Unfortunately, by selectively choosing timeframe, almost any position can be supported with a prudently screened data set. Statistics must always be fully scrutinized.
We agree that the article could have been more meticulously researched and more comprehensive. The cautionary “reader beware “ is warranted here.
Best Wishes.
