Diversification: A Potential Cure for Emotional Investor Behavior?
The concept of diversification is nothing new for investors. The adage “don’t put your eggs in one basket” simply states why diversification is vital. There are several potential benefits of a diversified multi-asset investment portfolio, and one of the most important is to reduce concentration risk. This is done in a number of ways, but primarily by investing in a variety of asset classes, industries and geographies. Additionally, diversification may help smooth out returns in volatile times, it may provide for higher returns over longer time periods and it may help investors avoid the pitfalls of emotionally based investment decisions.
Concentration risk is essentially the risk from investing in a single asset class or single region. A diversified multi-asset portfolio typically has exposure to a variety of asset classes as well as regions.History has demonstrated that all asset classes have market cycles where they perform well and cycles where they trail.Additionally, history has shown some asset classes are going to do well when others are lagging.For instance, commodities tend to be an asset class with a lower correlation to U.S. equities.Since it is nearly impossible to predict which asset classes are going to lead or trail in any given year, and we have seen that asset classes can go from leaders to trailers suddenly and with little to no warning, we believe it is important to stay diversified and stay invested over the long-term.
Market leadership rotation
Most recently investors have questioned the value of owning anything other than U.S. stocks. Looking at the chart below, we see U.S. equities have outperformed non-U.S. equities for the last 37 quarters! However, a couple of things that are evident in this chart are the abrupt shift that occurs when leadership rotates, and that leadership does indeed rotate.

May help smooth out returns in volatile times
In addition to the idea that diversification may help protect a portfolio’s return when asset class leadership rotates, it also may help smooth out a portfolio’s return when market volatility increases.A properly diversified portfolio may have lower drawdowns and reduce risk over the long-term.That said, a balanced return may be less than the best performing asset class and better than the worst.
In the chart below, we can see a visual representation of this. At the end of Q4 2018, we saw a significant market correction that saw U.S. stocks, represented by the S&P 500, end the year down -13.5%. However, for the same period a balanced portfolio comprised of U.S., international, emerging markets, real estate, commodities and fixed income was only down -6.9% for the same period. As markets rebounded in Q1/Q2 2019, we saw U.S. stocks jump +18.5% and we saw the balanced portfolio return +12.2%. In both instances, the balanced portfolio exhibited less volatility compared to U.S. stocks, but at the end of the two periods it provided a positive total return of +3.8%—outperforming U.S. stocks, which finished up +2.5%. Remember, past performance is no guarantee of future results.

Diversification provides the opportunity to smooth out returns in volatile times and helps mitigate risk in a portfolio.It is about being flexible, balanced and focused on a long-term goal. Investors diversify because the future is uncertain, and no one can predict with certainty which asset class will win or lose over the upcoming cycles.

This process is known as "rolling" a futures position.
