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:

'The total return on a portfolio of investments takes into account not only the capital appreciation on the portfolio, but also the income received on the portfolio. The income typically consists of interest, dividends, and securities lending fees. This contrasts with the price return, which takes into account only the capital gain on an investment.'

Which means for our asset as example:
  • The total return over 5 years of Enhanced Permanent Portfolio Strategy is 57.8%, which is lower, thus worse compared to the benchmark SPY (109.7%) in the same period.
  • Compared with SPY (70.1%) in the period of the last 3 years, the total return of 42.7% is smaller, thus worse.

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.'

Which means for our asset as example:
  • Compared with the benchmark SPY (16%) in the period of the last 5 years, the compounded annual growth rate (CAGR) of 9.6% of Enhanced Permanent Portfolio Strategy is smaller, thus worse.
  • Compared with SPY (19.5%) in the period of the last 3 years, the annual return (CAGR) of 12.6% is smaller, thus worse.

Volatility:

'Volatility is a rate at which the price of a security increases or decreases for a given set of returns. Volatility is measured by calculating the standard deviation of the annualized returns over a given period of time. It shows the range to which the price of a security may increase or decrease. Volatility measures the risk of a security. It is used in option pricing formula to gauge the fluctuations in the returns of the underlying assets. Volatility indicates the pricing behavior of the security and helps estimate the fluctuations that may happen in a short period of time.'

Applying this definition to our asset in some examples:
  • The historical 30 days volatility over 5 years of Enhanced Permanent Portfolio Strategy is 8.9%, which is lower, thus better compared to the benchmark SPY (17.5%) in the same period.
  • Compared with SPY (17.4%) in the period of the last 3 years, the historical 30 days volatility of 9.1% is smaller, thus better.

DownVol:

'Downside risk is the financial risk associated with losses. That is, it is the risk of the actual return being below the expected return, or the uncertainty about the magnitude of that difference. Risk measures typically quantify the downside risk, whereas the standard deviation (an example of a deviation risk measure) measures both the upside and downside risk. Specifically, downside risk in our definition is the semi-deviation, that is the standard deviation of all negative returns.'

Using this definition on our asset we see for example:
  • The downside volatility over 5 years of Enhanced Permanent Portfolio Strategy is 6.1%, which is lower, thus better compared to the benchmark SPY (12.1%) in the same period.
  • During the last 3 years, the downside volatility is 6%, which is lower, thus better than the value of 11.5% from the benchmark.

Sharpe:

'The Sharpe ratio is the measure of risk-adjusted return of a financial portfolio. Sharpe ratio is a measure of excess portfolio return over the risk-free rate relative to its standard deviation. Normally, the 90-day Treasury bill rate is taken as the proxy for risk-free rate. A portfolio with a higher Sharpe ratio is considered superior relative to its peers. The measure was named after William F Sharpe, a Nobel laureate and professor of finance, emeritus at Stanford University.'

Using this definition on our asset we see for example:
  • The Sharpe Ratio over 5 years of Enhanced Permanent Portfolio Strategy is 0.8, which is higher, thus better compared to the benchmark SPY (0.77) in the same period.
  • During the last 3 years, the Sharpe Ratio is 1.11, which is greater, thus better than the value of 0.97 from the benchmark.

Sortino:

'The Sortino ratio improves upon the Sharpe ratio by isolating downside volatility from total volatility by dividing excess return by the downside deviation. The Sortino ratio is a variation of the Sharpe ratio that differentiates harmful volatility from total overall volatility by using the asset's standard deviation of negative asset returns, called downside deviation. The Sortino ratio takes the asset's return and subtracts the risk-free rate, and then divides that amount by the asset's downside deviation. The ratio was named after Frank A. Sortino.'

Which means for our asset as example:
  • Compared with the benchmark SPY (1.12) in the period of the last 5 years, the excess return divided by the downside deviation of 1.16 of Enhanced Permanent Portfolio Strategy is larger, thus better.
  • Looking at downside risk / excess return profile in of 1.69 in the period of the last 3 years, we see it is relatively higher, thus better in comparison to SPY (1.47).

Ulcer:

'Ulcer Index is a method for measuring investment risk that addresses the real concerns of investors, unlike the widely used standard deviation of return. UI is a measure of the depth and duration of drawdowns in prices from earlier highs. Using Ulcer Index instead of standard deviation can lead to very different conclusions about investment risk and risk-adjusted return, especially when evaluating strategies that seek to avoid major declines in portfolio value (market timing, dynamic asset allocation, hedge funds, etc.). The Ulcer Index was originally developed in 1987. Since then, it has been widely recognized and adopted by the investment community. According to Nelson Freeburg, editor of Formula Research, Ulcer Index is “perhaps the most fully realized statistical portrait of risk there is.'

Applying this definition to our asset in some examples:
  • The Ulcer Ratio 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.
  • During the last 3 years, the Downside risk index is 3.38 , which is lower, thus better than the value of 5.3 from the benchmark.

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:
  • Compared with the benchmark SPY (-24.5 days) in the period of the last 5 years, the maximum DrawDown of -14.9 days of Enhanced Permanent Portfolio Strategy is higher, thus better.
  • During the last 3 years, the maximum DrawDown is -11.6 days, which is higher, thus better than the value of -18.8 days from the benchmark.

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.'

Which means for our asset as example:
  • Looking at the maximum days under water of 564 days in the last 5 years of Enhanced Permanent Portfolio Strategy, we see it is relatively higher, thus worse in comparison to the benchmark SPY (488 days)
  • Compared with SPY (199 days) in the period of the last 3 years, the maximum time in days below previous high water mark of 226 days is higher, thus worse.

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 days below previous high 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.
  • Looking at average time in days below previous high water mark in of 50 days in the period of the last 3 years, we see it is relatively higher, thus worse in comparison to SPY (47 days).
