Description

The classic permanent portfolio was created by Harry Browne. The idea was that a portfolio should be diversified enough to get you through a wide variety of economic and market environments and simple enough that even a child could do it. Originally it consisted of the following allocations:

  • 25% in U.S. stocks
  • 25% in long-term bonds
  • 25% in gold
  • 25% in cash

The Logical Invest permanent portfolio is somewhat more sophisticated, rebalances monthly and is not always split evenly across the three main assets. It can adapt to market conditions by putting more weight on gold or treasuries and less on equity depending on market conditions.

Methodology & Assets
  • US Market (SPY: S&P 500 SPDRs)
  • Long Duration Treasuries (TLT: iShares 20+ Year Treasury Bond)
  • Gold (GLD: Gold Shares SPDR)

Statistics (YTD)

What do these metrics mean? [Read More] [Hide]

TotalReturn:

'Total return, when measuring performance, is the actual rate of return of an investment or a pool of investments over a given evaluation period. Total return includes interest, capital gains, dividends and distributions realized over a given period of time. Total return accounts for two categories of return: income including interest paid by fixed-income investments, distributions or dividends and capital appreciation, representing the change in the market price of an asset.'

Applying this definition to our asset in some examples:
  • The total return, or performance over 5 years of Enhanced Permanent Portfolio Strategy is 62.1%, which is lower, thus worse compared to the benchmark SPY (106.2%) in the same period.
  • Looking at total return, or increase in value in of 43.6% in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (69%).

CAGR:

'The compound annual growth rate (CAGR) is a useful measure of growth over multiple time periods. It can be thought of as the growth rate that gets you from the initial investment value to the ending investment value if you assume that the investment has been compounding over the time period.'

Using this definition on our asset we see for example:
  • The annual return (CAGR) over 5 years of Enhanced Permanent Portfolio Strategy is 10.2%, which is lower, thus worse compared to the benchmark SPY (15.6%) in the same period.
  • During the last 3 years, the annual performance (CAGR) is 12.9%, which is smaller, thus worse than the value of 19.2% from the benchmark.

Volatility:

'In finance, volatility (symbol σ) is the degree of variation of a trading price series over time as measured by the standard deviation of logarithmic returns. Historic volatility measures a time series of past market prices. Implied volatility looks forward in time, being derived from the market price of a market-traded derivative (in particular, an option). Commonly, the higher the volatility, the riskier the security.'

Which means for our asset as example:
  • The historical 30 days volatility over 5 years of Enhanced Permanent Portfolio Strategy is 8.9%, which is smaller, thus better compared to the benchmark SPY (17.6%) in the same period.
  • Looking at historical 30 days volatility in of 9.1% in the period of the last 3 years, we see it is relatively smaller, thus better in comparison to SPY (17.7%).

DownVol:

'The downside volatility is similar to the volatility, or standard deviation, but only takes losing/negative periods into account.'

Using this definition on our asset we see for example:
  • The downside risk over 5 years of Enhanced Permanent Portfolio Strategy is 6.1%, which is smaller, thus better compared to the benchmark SPY (12.2%) in the same period.
  • During the last 3 years, the downside deviation is 6%, which is lower, thus better than the value of 11.6% from the benchmark.

Sharpe:

'The Sharpe ratio (also known as the Sharpe index, the Sharpe measure, and the reward-to-variability ratio) is a way to examine the performance of an investment by adjusting for its risk. The ratio measures the excess return (or risk premium) per unit of deviation in an investment asset or a trading strategy, typically referred to as risk, named after William F. Sharpe.'

Applying this definition to our asset in some examples:
  • Looking at the risk / return profile (Sharpe) of 0.86 in the last 5 years of Enhanced Permanent Portfolio Strategy, we see it is relatively higher, thus better in comparison to the benchmark SPY (0.74)
  • Compared with SPY (0.94) in the period of the last 3 years, the risk / return profile (Sharpe) of 1.13 is greater, thus better.

Sortino:

'The Sortino ratio measures the risk-adjusted return of an investment asset, portfolio, or strategy. It is a modification of the Sharpe ratio but penalizes only those returns falling below a user-specified target or required rate of return, while the Sharpe ratio penalizes both upside and downside volatility equally. Though both ratios measure an investment's risk-adjusted return, they do so in significantly different ways that will frequently lead to differing conclusions as to the true nature of the investment's return-generating efficiency. The Sortino ratio is used as a way to compare the risk-adjusted performance of programs with differing risk and return profiles. In general, risk-adjusted returns seek to normalize the risk across programs and then see which has the higher return unit per risk.'

Using this definition on our asset we see for example:
  • The excess return divided by the downside deviation over 5 years of Enhanced Permanent Portfolio Strategy is 1.26, which is larger, thus better compared to the benchmark SPY (1.08) in the same period.
  • Looking at downside risk / excess return profile in of 1.73 in the period of the last 3 years, we see it is relatively larger, thus better in comparison to SPY (1.44).

Ulcer:

'The ulcer index is a stock market risk measure or technical analysis indicator devised by Peter Martin in 1987, and published by him and Byron McCann in their 1989 book The Investors Guide to Fidelity Funds. It's designed as a measure of volatility, but only volatility in the downward direction, i.e. the amount of drawdown or retracement occurring over a period. Other volatility measures like standard deviation treat up and down movement equally, but a trader doesn't mind upward movement, it's the downside that causes stress and stomach ulcers that the index's name suggests.'

Which means for our asset as example:
  • The Downside risk index over 5 years of Enhanced Permanent Portfolio Strategy is 4.5 , which is lower, thus better compared to the benchmark SPY (8.48 ) in the same period.
  • Looking at Ulcer Index in of 3.38 in the period of the last 3 years, we see it is relatively lower, thus better in comparison to SPY (5.31 ).

MaxDD:

'A maximum drawdown is the maximum loss from a peak to a trough of a portfolio, before a new peak is attained. Maximum Drawdown is an indicator of downside risk over a specified time period. It can be used both as a stand-alone measure or as an input into other metrics such as 'Return over Maximum Drawdown' and the Calmar Ratio. Maximum Drawdown is expressed in percentage terms.'

Applying this definition to our asset in some examples:
  • The maximum drop from peak to valley over 5 years of Enhanced Permanent Portfolio Strategy is -14.9 days, which is higher, thus better compared to the benchmark SPY (-24.5 days) in the same period.
  • Compared with SPY (-18.8 days) in the period of the last 3 years, the maximum DrawDown of -11.6 days is larger, thus better.

MaxDuration:

'The Drawdown Duration is the length of any peak to peak period, or the time between new equity highs. The Max Drawdown Duration is the worst (the maximum/longest) amount of time an investment has seen between peaks (equity highs) in days.'

Applying this definition to our asset in some examples:
  • Looking at the maximum time in days below previous high water mark of 564 days in the last 5 years of Enhanced Permanent Portfolio Strategy, we see it is relatively larger, thus worse in comparison to the benchmark SPY (488 days)
  • Looking at maximum days under water in of 226 days in the period of the last 3 years, we see it is relatively larger, thus worse in comparison to SPY (199 days).

AveDuration:

'The Drawdown Duration is the length of any peak to peak period, or the time between new equity highs. The Avg Drawdown Duration is the average amount of time an investment has seen between peaks (equity highs), or in other terms the average of time under water of all drawdowns. So in contrast to the Maximum duration it does not measure only one drawdown event but calculates the average of all.'

Using this definition on our asset we see for example:
  • The average time in days below previous high water mark over 5 years of Enhanced Permanent Portfolio Strategy is 150 days, which is higher, thus worse compared to the benchmark SPY (120 days) in the same period.
  • During the last 3 years, the average days under water is 50 days, which is greater, thus worse than the value of 46 days from the benchmark.
