Zweig Bond Model Signals What ETFs To Be In

July 19, 2016

So, What To Do With Bonds?

I've long been a fan of the great Marty Zweig. In the mid-1980s, Marty and Ned Davis Research (NDR) created the Zweig bond model. Back then, the world was dealing with a rising interest rate environment. The 10-year yield peaked at 14% in 1984.

We did some work with NDR and recreated the simple trend-following model, and we use it internally to help us invest in longer-dated bond ETFs or switch to shorter-dated bond ETFs, such as the SPDR Barclays 1-3 Month T-Bill ETF (BIL | A-62) or the PIMCO Enhanced Short Maturity Active ETF (MINT | B).

It kept us invested in high-quality, longer-dated bond ETFs despite the fundamental forecasts that called for higher interest rates. As the axiom goes, "Let the trend be your friend."

5 Steps To The Model

It is a simple process and you can do this yourself. There are five steps to the Zweig bond model's scoring process:

  1. Score a +1 when the Dow Jones 20 Bond Price Index (index symbol $DJCBP) rises from a bottom price low by 0.6%. Score a -1 when the index falls from a peak price by 0.6%.
  2. Score a +1 when the Dow Jones 20 Bond Price Index rises from a bottom price by 1.8%. Score a -1 when the index falls from a peak price by 1.8%.
  3. Score a +1 when the Dow Jones 20 Bond Price Index crosses above its 50-day moving average by 1%. Score a -1 when the index crosses below its 50-day MA by 1%.
  4. Score a +1 when the Fed Funds Target Rate drops by at least 0.50%. Score a -1 when the rate rises by at least 0.50% point. Score +1 if a buy and -1 if a sell.
  5. Score a +1 when the yield difference of the Moody's AAA Corporate Bond Yield minus the yield on 90-day Commercial Paper Yield crosses above 0.60%. Score a -1 when the yield difference falls below -0.20%. Score it 0 for a neutral score between -0.20% and 0.60%.

Next, sum the scores of steps 1 through 5 once a week. The current reading is +3. (The chart below reflects calculations as of close on July 11. See yellow highlight bottom right-hand corner.)

If the total is +1 or higher, we would suggest considering a total bond market ETF such as TLT, the Vanguard Extended Duration Treasury Index Fund (EDV | C-50), the Vanguard Total Bond Market Index Fund (BND | A-94) or the iShares Barclays Aggregate Bond ETF (AGG | A-98).

If the aggregate score is -1 or lower, we would suggest considering BIL or MINT.

Let The Trend Be Your Friend

The objective is to stay in line with the bond market's primary trend.

With interest rates at 5,000-year lows, one has to take a step back and consider solutions that can better manage risk. We are living in a highly unusual and experimental central bank policy world. Yet there are ways for you to make money, using the broad set of tools ETFs provide.
