Asia Fixed Income: China – What’s More Than Yields?

Exhibit 1 shows the correlation of the S&P China Sovereign Bond Index with major sovereign bond indices in global markets. While the index has a low correlation of 0.09 with Read more […]

Asia Fixed Income: Diversifying into Chinese Bonds

Sorry, Wrong Number

Last week brought yet another indication that 2014 is proving to be a very difficult environment for active stock selection strategies.  With the majority of large cap U.S. equity managers underperforming the S&P 500, “only performances in 2006, 2010 and 2011 have been as bad or worse than the current year’s pace.” Well, in any Read more […]

Why are active managers lagging?

In late 2013 and early 2014, we heard considerable chatter about the coming “stock picker’s market.”  2014 would favor stock selection strategies, it was said, because intra-market correlation was falling as macro-economic risks receded.  This morning’s Wall Street Journal reports that the contrary view — that low levels of stock market dispersion would make 2014 an Read more […]

Don’t Put All Your Eggs In One Basket

It’s a little late for an Easter post but this saying is about one of the key investment principles, diversification.  Simply put, diversification happens when assets inside your portfolio move in opposite directions. The investment measure of diversification is correlation and it can range from -1.0 to +1.0. If correlation is -1.0 between two assets, Read more […]

An Immediate Risk Measure

Volatility and correlation are history. In fact this is a consequence of their definitions.  The calculation of volatility and correlation – the preeminent measures of risk – requires multiple observations.  Quite a few periods are needed if the resulting estimates are to be relied upon as robust.   Because of this, volatility and correlation are not Read more […]

Right Conclusion (maybe), Wrong Reason (definitely)

This morning’s Wall Street Journal joined (actually, re-enlisted in) the chorus of those arguing that 2014 would be a time for stock pickers to “shine.”  The lynchpin of the Journal‘s case will be familiar to advocates of a “stock-picker’s market.”  That argument is that since correlations in the U.S. equity market are declining (perhaps as Read more […]

Some Inconvenient Truths

Today’s Wall Street Journal brought the latest in a string of articles suggesting that we have entered a period of particular opportunity for active investment management — a so-called “stock-picker’s market.”  Because the average correlation of stocks within the S&P 500 or other major indices has declined, it’s argued, “active managers are going to do Read more […]

Dispersion and Correlation: Which is “Better?”

We recently introduced the concept of dispersion, which measures the average difference between the return of an index and the return of each of the index’s components.  In times of high dispersion, the gap between the best performers and the worst performers is relatively wide; when dispersion is low, the performance gap narrows.  Today’s dispersion Read more […]

Low Dispersion Implies Low Value Added

Understanding a market’s dispersion provides important insights into its internal dynamics and the opportunities and pitfalls that might await both active and passive investors.  Dispersion measures the average difference between the return of an index and the return of each of the index’s components.  In times of high dispersion, the gap between the best performers Read more […]
