Why you should choose iShares GSCI Commodity Dynamic Roll Strategy ETF

When you pick a good commodity ETF you need to look at 6 things:

  1. The expense ratio for the ETF needs to be low. The expense ratio is always expressed as a percentage. The percentage denotes how much of your total investment in that ETF that you need to pay the provider. This should be below 0.30% and preferrably lower than that.
    For commodity ETFs the expense ratio is usually a bit higher. This is because commodity ETFs buy futures contracts on the commodities that the ETF wants to gain exposure to. Buying futures contracts is more expensive than buying stocks.
  2. The ETF should invest passively. It should follow a well-established index from a reputable provider like MSCI, Morningstar, or FTSE. Passivly managed funds typically beats actively managed funds on expenses and investment returns.
  3. The ETF needs to be highly liquid. This means that the difference between the buy and sell price (bid/ask) for the ETF is small. This is called the price spread.
  4. The ETF needs to have large amount of assets under management. This is abbreviated as AUM. This guarantees that the ETF doesn’t close in the near future and is also an indicator of low price spreads.
  5. The ETF needs to follow its index without a large tracking error. If the ETF has a large tracking error in comparison to its index we are not getting what we are paying for. A large tracking error is also an indication that the ETF is executing poorly on its replication of the index that it is tracking which is not desireable.
  6. The index that the ETF tracks need to represent and replicate the desired asset class with high fidelity. This means we expect a commodity ETF to contain a broad basket of commodities and continue to do so without style drift.

When you are comparing the six requirements to each other the most important thing to focus on is the expense ratio, as that is the most reliable indicator of how well the ETF will perform in the future.

The iShares GSCI Commodity Dynamic Roll Strategy ETF fulfills all of the above requirements. It is cheaper than most other commodity ETFs and tracks a commodity well regarded broad commodity index with little tracking error. It is highly liquid with a large AUM.

How do I know if an ETF is a commodity ETF?

When you select an ETF to cover the commodity asset class you can clearly see which style the ETF uses by the name of the ETF.

Here are two examples:
• iShares GSCI Commodity Dynamic Roll Strategy ETF commodities ETF
• Invesco DB Commodity Index Tracking Fund

As you can see the ETFs clearly state the investing strategy of the ETF. In this case, it is commodities that the ETF is buying.

In addition to this, you need to examine the index that the ETF is tracking. Most index providers disclose their indexing methodology on a general level and even on a practical specific level for particular assets classes.

The large index providers have money on the line in providing the best indices for any one asset class. This means that we can typically rest assured that their methodology is far superior to any second-guessing that we as private investors may come up with.

For commodities, there are many different ways to construct an ETF. In the past 5 – 10 years we have seen many new commodity ETFs being launched with various ways of constructing an index.

One of the largest headwinds to a commodity ETF is the use of futures, swaps, or options to gain exposure to a commodity. These are called derivative products because their prices are derived from another asset. They need to be renewed regularly (rolled over) which costs money.

In addition to this, commodities can also be taxed differently than equities or bonds.

Why should I buy commodities?

Commodities experience some wild boom and bust cycles.

This is because at the start of a boom cycle mining producers ramp up their production to meet the production requirements of produces further down the value chain. Commodity prices are usually increasing in price at this stage.

When we reach the top and start of the decline of the economic cycle the commodity producers are at full capacity and many are expanding their production capabilities to meet demand, but that’s exactly when commodity prices will begin to stagnate.

As the economic cycle continues its downward trend demand weakens for commodities and prices fall even further. At this stage, commodity producers scale back their production levels but nowhere near fast enough to prevent the markets to be oversaturated with commodities. Commodity prices plummet marking the start of the bust cycle.

If you can catch the commodities asset class at the right time you stand to increase your wealth significantly.

How do I build a great portfolio with ETFs?

A high-performing portfolio is constructed by combining different asset classes. If you just want the market return you should buy one ETF (VTI). You don’t need anything else.

If you want a shot at outperforming the market you need to apply the following recipe to your investing strategy.

  1. Start with adding a broad US based stock ETF.
  2. Then, add exposure to international stocks. This is usually divided into developed countries and emerging markets. Developed markets include Europe, Canada, Japan, Australia and small parts of Asia. Emerging markets include Eastern Europe, Africa, most of Asia and Southamerica.
  3. Then tilt (overweight) your portfolio towards high performing asset classes like value and small-cap. Value stocks and smaller stocks have historically outpaced larger growth stocks. This has not been true in the past 10 years however.

If you want the best performing, pre-made, and benchmarked portfolios that we have tested then you should consider our premium service that shows you how to construct the best portfolios that we have benchmarked.
