Building a Permanent ETF Portfolio, Part 2

Earlier this week I proposed a 14 ETF portfolio intended to replicate the popular Permanent Portfolio mutual fund, PRPFX.  My original 14 ETF portfolio was intended to replicate PRPFX as closely as possible using liquid ETFs. The 14 positions could realistically be reduced to 8 while still maintaining a high correlation to the original 14 ETF portfolio.

The original 14 ETFs are listed below:

Ticker Name Allocation
FXF Swiss Franc CurrencyShares 10.00%
GLD SPDR Gold Shares 20.00%
HYG iShares iBoxx High-Yield Corp Bond (4-5yr) 5.00%
IEF iShares Barclays 7-10 Yr Treasury (7-8yr) 5.00%
IGE iShares S&P N. Amer Nat. Resources 5.00%
VUG Vanguard MSCI U.S. LargeCap Growth 7.50%
IWO iShares Russell 2000 Growth 7.50%
LQD iShares iBoxx Invest Grade Bond (7-8yr) 5.00%
RWX SPDR DJ International Real Estate 5.00%
SHY Barclays Low Duration Treasury (2-yr) 5.00%
SLV iShares Silver Trust 5.00%
TIP iShares Barclays TIPS (4-8yr) 10.00%
TLT iShares Barclays Long-Term Trsry (15-17yr) 5.00%
VNQ Vanguard MSCI U.S. REIT 5.00%

If we consolidate the stock and bond holdings, we are left with an 8 ETF portfolio that still closely maintains the stated portfolio structure and asset allocation  of PRPFX and, as we will see below, has been highly correlated to the 14 ETF portfolio:

AGG iShares Barclays Aggregate Bond (4-5yr) 35%
FXF Swiss Franc CurrencyShares 10%
GLD SPDR Gold Shares 20%
IGE iShares S&P N. Amer Nat. Resources 5%
RWX SPDR DJ International Real Estate 5%
SLV iShares Silver Trust 5%
VNQ Vanguard MSCI U.S. REIT 5%
VUG Vanguard MSCI U.S. LargeCap Growth 15%

Using ETFReplay.com, we see that both portfolios have shown a high correlation since 2008:

The 8 ETF portfolio had CAGR of 8.4% and a max drawdown of -25.25%. When we compare the 8 ETF portfolio to a 50/50 portfolio consisting of 50% SPY and 50% AGG, we see that the Permanent 8 portfolio significantly outpaced a 50/50 portfolio since 2008 with about the same volatility:

 

One of my favorite tools for potentially reducing portfolio volatility and drawdown is to use the 10 month simple moving average strategy, popularized in recent years by Mebane Faber in The Ivy Portfolio: How to Invest Like the Top Endowments and Avoid Bear Markets.

For example, the Permanent Portfolio has a 20% allocation to Gold, which is in the midst of a bull market.  When and if Gold begins a bear cycle, it could be a significant drag on the portfolio. By using a long-term moving average signal, we could potentially reduce portfolio drawdown created when any one of the holdings enters a bear market.

The results for a 10 month moving average system on the 8 ETF Permanent portfolio are below (2008-present). When an ETF in the portfolio was below its 10 month moving average at month-end, the position was sold and held in “cash” (SHY was used as the cash position). When it closed the month above its 10 month moving average, the ETF was purchased and held until the close of the next month:

The results were not as dramatic as I expected. Portfolio drawdown was reduced to -16% versus -25.25% for buy and hold of the same portfolio. Volatility was reduced slightly to 11.5% and total return actually increased slightly to 41.4%. An improvement in all areas, yes, but not significant.

Finally, what if we simply purchased the 2 ETFs with the strongest momentum within the Permanent 8 ETF portfolio? This is a similar strategy used in my monthly ETF Replay Portfolio. Purchasing the 2 ETFs out of the 8 with the highest 6 month returns and rebalancing monthly yield the following results (2008-present):

If we purchased the top 2 ETFs as gauged by a combination of their 6 month return, 3 month return, and 3 month volatility, and rebalanced monthly, the results are below:

If we reduce the time frame to a 3 month return, 20 day return and 20 volatility, the historical results are better:

Holding only 2 ETFs increases portfolio volatility, which should be expected, but did not necessarily increase returns versus buy and hold or the 10 month simple moving average system.

The goal here is not to identify “the best” solution, since past results are no guarantee of future returns. It is to propose a relatively simple ETF portfolio to mimic PRPFX and to explore and test additional risk management and trading techniques within the ETF portfolio.

  1. Why not just buy 25% GLD, 25% LTT, 25% stocks and
    25% cash (say, SHY). The replicates Harry Browne’s concept and yielded 10% last year. And without the aggrevation. In fact it had no loss in ’08/’09 and has done 10% at least for the last 10 yrs annualized…

    • Within the next week or so I will be featuring Harry Browne’s version. Again, these aren’t recommendations or trying to pick the best strategy, simply analysis. This “Permanent ETF Portfolio” highlighted my ETF version of PRPFX

  2. Scott, I like anything that deals with H Browne. I own a lot of PRPFX, as do my boys. Living in middle Tenn got me started when Harry ran for POTUS on the Libertarian ticket. Harry lived nearby.

    PRPFX had about 6-700 mil in assets back then, now 15 bil.

    This is a link announcing a new book, also if one scrolls down you can see the returns on the classic PP since 1972.
