Getting A Feel For The DB Commodity Index: DBC

Mar 26, 2011 in Commodities

The business cycle favors different segments of the investment landscape at different times. Good relative strength analysis helps read money flows to give a view on how the market is indicating where we are in the business cycle in terms of stocks, bonds & commodities.

We highlighted the Deutsche Bank Commodity Index ETN (DBC) late last month and let's now take a closer look. One thing about the exchange traded market is that unlike being a stock generalist where various names turn over and you may never come back to some of them, what you learn now about the core ETF/ETN products will likely remain relevant for the rest of your investing life. One such family of indexes to get to know is the Deutsche Bank Commodity indices.

The DB Commodity index has four distinct components: Energy, Agriculture, Base Metals & Precious Metals. Each component has the convenient symbol structure of DB_ with the final letter telling you what it is. ie, DB[E] is Energy.

Deutsche Bank built DBC based on fourteen of the most heavily traded and important physical commodities in the world. "The Index commodity components were chosen based on the depth and liquidity of their markets and to provide diversified commodity performance." It makes sense that since Energy is the most economically important commodity group in the world, it should get the largest weight. That said, Deutsche Bank found a balance for diversification purposes and kept the energy component at 55%.

Below is a graph of the components and performance for this month. You can see that while precious metals have been strong (particularly Silver SLV), that the 10% weighting of Precious Metals is relatively small. The real driver here has been energy. Agriculture ( DBA) is down for the month but this has been dwarfed by the strength in the energy complex.

 

While commodities are less correlated to stocks than many other indices are to stocks, it should be pointed out that both commodities and stocks are at the core related to economic strength. That is, a bad economy reduces demand for commodities and also hurts corporate earnings, which negatively affects stocks. Correlations over time can be erratic so we need to be careful on assuming too much with regard to the diversification benefits of commodities.

Backtests Become Forward Tests

Mar 18, 2011 in Backtest

It is well accepted in professional money management that having a quantitative aspect to your investment process is additive. That is, quantitative methods can greatly help in screening and monitoring lists of securities into a manageable ranking for further analysis. The vast majority of institutional-oriented firms do this kind of thing.

The classic, basic steps of an investment process involve:

1. Install a (Quantitative) Method To Rank A Relevant Universe of Securities
2. Take The Top-Ranked Securities And Do Further Research
3. Construct a Portfolio Using Securities That Pass The First 2 Steps
4. Monitor And Update The Portfolio
5. Repeat

We view backtesting as a very practical and useful part of the research process. The way you rank securities should be based on something consistent with your beliefs on what actually works.

Once you have done some research and found a method to rank securities, run some backtests. You will learn about your method greatly and can understand more aspects and characteristics of such strategies. You will speed up your understanding and you will be forced to think through all the details of how you are going to execute your process.

Once you have created a portfolio (per Step 3 above), that portfolio effectively now becomes a ‘forward-test.’ Monitoring these portfolios and seeing these various rotation strategies behave is a crucial part of the process. Track your various rotation strategies. You can learn a lot by running many simultaneous ‘forward tests’ at once. Importantly, you will get a feeling for the ‘short-term noise’ that occurs around your strategy. Even for professionals, the psychological aspects of short-term volatility will cause them to doubt themselves. Back/Forward tests will make you much more aware of the kind of thing you will face in the future. You must get used to this as psychological aspects to investing are absolutely critical.

Back/forward-testing accelerates the learning process and you can then feed the incremental improvements you discover back into your actual portfolio. The point is that just doing a backtest and then ‘stopping your research’ is very limiting. Don’t stop learning, don’t stop improving. Small incremental improvements add up over time.

We are entering the golden age of active indexing. The specialized, targeted index fund is really a somewhat new phenomenon. Index funds in the 1980s were all very broad vehicles. Many specialized index products (Vanguard REIT index mutual fund, country fund ETFs) actually only have histories back to 1996. You can simulate prior performance -- but they weren't so inexpensively accessible. TIPS securities weren’t even issued by the Treasury until 1997. The World Equity Index products (mutual fund AND etf) didn’t launch until 2008.

Important new areas of future investment may come from newly investable products. For example, the emerging markets small cap index might become as mainstream a product as some other well-accepted benchmarks are today. Understanding the important indices of tomorrow might be as good an idea as understanding REIT and emerging markets indices when they were new PRODUCTS (ie, investable and tradeable at reasonable cost).

Understanding and processing relative performance, relative volatilities and observing relative drawdowns in present ‘forward-test’ environment strikes us as a pretty good idea.

iShares is bringing to market an Internationally focused preferred stock index. Wisdomtree just launched an Asia-Pacific regional intermediate bond ETF. Remember that at one point, the emerging markets index mutual fund was brand new (1994).  Today it is a primary index everyone follows.   Growth vs value wasn’t mainstream until the 1990s -- and indexing these products came later.  The world evolves.  Embrace the change and learn from it – let many simultaneous forward tests accelerate the learning.

Commodity ETF Products At A Glance

Mar 03, 2011 in Commodities

ETF investors have been especially fond of energy stock ETFs. Here is a combined look at the growing popularity (and underlying appreciation) of energy equity ETFs from the 'Big 3' (SPDR, iShares and Vanguard).

 

But perhaps more important is the continued growth of commodity exchange-traded products. Many tactical participants consider commodites to have cleaner trending behavior than stocks and therefore somewhat easier to trade. We won't attempt to try to show this within a blog. We will point out though that there are also options markets made on commodity ETPs as another way to access these markets.

It's interesting to take a look at the amount of money being made off these growing asset bases by the providers. This has become significant. Even excluding Gold products (GLD, IAU, DBP etc...) and only using the top 13 as a sample, we see these products generating approximately $220 million in annualized fees at current (February month-end) levels. If you include GLD and others, this number more than doubles --- call it $450 million. While that sounds like a lot, consider that these products charge less than 1/2 of what mutual funds charge on a percentage basis. And mutual funds have $9 trillion in assets. (note that Vanguard has not entered the commodity ETN space or else things might be different).

 

By viewing assets, we see the combination of price strength and investor inflows/outflows -- which has caused this group to rise very quickly. I put these 13 together to show the growth in assets since the middle of 2009:

 

Finally, I used the free Backtest Portfolio Allocations App to create my own custom equal-weighted master index that shows the actual investor ETN return since the middle of 2010 (excludes USCI because its history is too short).
