Some Things Never Change…or Do They?

A popular debate in the asset management industry is “passive” vs. “active” investing.  Index-based investment vehicles have gathered a significant amount of assets over the last decade, to the detriment of active investing, perpetuating this debate even further.

While there is a misconception among some in the investing public surrounding the attributes of index-based investing, there is nothing “passive” about managing an index-based portfolio. As such, we tend to dislike using the word “passive” and instead prefer “index”. Not only does tracking the index require skill and resources, but the creation of the index and constant monitoring require experience and astuteness

From the set-up of the portfolio allocation, selection of the underlying investments, to the ongoing monitoring and account maintenance, a lot of time, energy and resources are devoted to these so-called “passive” strategies.

Read the Label Before Digging In

We are constantly bombarded with labels and disclosures in our lives.  From the food we eat to the shirt we wear, nearly everything has a label.  This often numbs our senses when it comes to certain items.  Likewise, we typically don’t understand more than 50% of the ingredients in our breakfast cereal, let alone something more technical.  Instead of differentiating through the information on the label, the annoyance and complexity of the label itself often drives us to view things as commodities.

We believe that many investors have this same attitude concerning index investments. With the complexity of the disclosures, investors tend to rely instead on the broad marketing names of the funds.  This can be a dangerous strategy.

Remember to Monitor

One area of index-based investing which requires a lot of time is the ongoing monitoring of the underlying indexes.  This is a task which many investors do not think much about, but can have a profound impact on their portfolio.  Investors often buy a large cap fund that tracks the S&P 500 index fund, for example, and expect it to track the S&P 500 forever.  However, what if that large cap index fund switches indexes to the Russell 1000?  While not a large change in allocation, it could have impact on other, overlapping holdings in the portfolio.

Examples are Common

Last summer, Vanguard announced a series of index changes to four of their international equity ETFs. Specifically, Vanguard Emerging Markets Stock Index (NYSEArca: VWO) moved from the FTSE Emerging Index to the FTSE Emerging Markets All Cap China A Inclusion Index. The goal for the change was twofold:  broader diversification and exposures to new markets.  While both of these objectives are great investment ideas, if an investor was not monitoring the indexes being tracked by their investments, their portfolio exposures could have unexpectedly shifted.

Taking a look at each goal separately, we can see how changing the underlying index has an impact on the position’s exposure.  First, the broader diversification was achieved by the inclusion of small cap equities.  Before the inclusion, an investor may have been using a different fund to gain exposure to emerging markets small cap.  If adjustments are not made, they may now have an overweight to this asset class without realizing it.

The second objective was providing exposure to new markets, mainly the China A share market.  China A shares are equities which trade on the Shanghai and Shenzhen stock exchanges and were historically only available to domestic Chinese investors.  It is a sizeable market with $6 trillion of market cap at the end of 2014 so their inclusion into the FTSE Index, and subsequent VWO Index change were significant events.

As can be seen above, the overall exposure to China within the ETF increased from 26% to almost 30% once the index transition is completed.  Again, an investor who built their overall portfolio allocation utilizing exposure information from the old index may unknowingly be increasing their overall exposure to China. In this instance, an investor may look to complement VWO with an ETF like EGShares EM Core ex-China ETF (NYSEArca: XCEM) in order to get the overall China exposure back to the initial level.

Index-based investing is not a set-it and forget-it operation.  It is important for not only retail investors, but also financial professionals to continuously monitor their investment vehicles to ensure appropriate exposure for their portfolios.  Index changes, while infrequent, do occur and can have a dramatic impact on the exposure of a portfolio, depending on the level investment concentration.
