Despite a tumultuous month, nothing really new came to light. Contrarily, we believe markets finally began to recognize many of the imbalances that have been percolating in plain sight. Nonetheless, we are pleased to say our portfolios performed quite well. Importantly, the daily volatility of our portfolios remained within their normal range, realizing only a fraction of what occurred in broad financial markets.
Insulating portfolios in times of stress has many advantages, but two are particularly important. First, as shown in Chart 1 below, given similar expected returns, a portfolio with less volatility will compound at faster ‘geometric’ rates, leading to greater cumulative wealth. Secondly, throughout the month we were able to remain confident and focused, recognizing our fortuitous position of being a potential buyer of risk at more attractive valuations while other investors seemingly panicked.
To look more closely at why our portfolio seemed to “work” during the month, consider the following: in constructing portfolios we focus on a few parameters for each asset class: expected return, volatility and correlation. These broad assumptions are then reconciled with our themes, which then undergo various scenario analyses. Should certain events unfold, it’s helpful to develop a view on how various asset classes are likely to react in absolute terms, as well as relative to each other. This is the essence of portfolio construction.
Much of the positive contribution this year has come from our allocation to gold and gold-related equities (one of our largest detractors earlier in the year). As you can see in Chart 2, recently the correlation of gold relative to equities has been highly negative, meaning gold has tended to rise when equities fell, and vice versa. Importantly, because gold has risen more than equities have fallen, our portfolios benefitted. This negative correlation—combined with slowing global growth (inspiring more monetary stimulus) and the escalating stress in Europe—has allowed us to maintain our core position, despite meaningful appreciation that may ordinarily lead us to trim. In sum, by monitoring the relationship of gold to other asset classes, we were encouraged to keep what we believed to be much-needed insurance.
However, we also know that over longer time horizons correlations are fairly unstable. What has benefitted us recently can be reversed instantly. Therefore, we have reinstated a quasi “hedge”—a long position in the US dollar. In essence, we believe the USD will rise relative to the euro, the yen and the pound and that gold will rise relative to all. However, by effectively denominating part of our gold position in these currencies, we hopefully remove some of the potential volatility of the position. In the near term, stress in the European banking system is likely to be dollar positive.
Chart 1 – By reducing volatility, capital compounds more quickly, leading to greater amounts of cumulative wealth. The volatility, or standard deviation, of global equity markets averages ~20%. Assuming similar rates of returns, diversified portfolios with a volatility of 5% will lead to greater wealth…

Chart 2 – The correlation of gold to equities oscillates over time. However, attempting to understand the fundamental drivers of asset classes and the broader macroeconomic landscape can help immensely with portfolio construction…
