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.'

Using this definition on our asset we see for example:
  • Compared with the benchmark SPY (94.2%) in the period of the last 5 years, the total return, or increase in value of 62.6% of Enhanced Permanent Portfolio Strategy is lower, thus worse.
  • During the last 3 years, the total return is 14.4%, which is lower, thus worse than the value of 27.9% from the benchmark.

CAGR:

'Compound annual growth rate (CAGR) is a business and investing specific term for the geometric progression ratio that provides a constant rate of return over the time period. CAGR is not an accounting term, but it is often used to describe some element of the business, for example revenue, units delivered, registered users, etc. CAGR dampens the effect of volatility of periodic returns that can render arithmetic means irrelevant. It is particularly useful to compare growth rates from various data sets of common domain such as revenue growth of companies in the same industry.'

Applying this definition to our asset in some examples:
  • Looking at the annual return (CAGR) of 10.2% in the last 5 years of Enhanced Permanent Portfolio Strategy, we see it is relatively lower, thus worse in comparison to the benchmark SPY (14.2%)
  • Compared with SPY (8.6%) in the period of the last 3 years, the annual performance (CAGR) of 4.6% is smaller, thus worse.

Volatility:

'Volatility is a statistical measure of the dispersion of returns for a given security or market index. Volatility can either be measured by using the standard deviation or variance between returns from that same security or market index. Commonly, the higher the volatility, the riskier the security. In the securities markets, volatility is often associated with big swings in either direction. For example, when the stock market rises and falls more than one percent over a sustained period of time, it is called a 'volatile' market.'

Applying this definition to our asset in some examples:
  • Looking at the 30 days standard deviation of 9.5% in the last 5 years of Enhanced Permanent Portfolio Strategy, we see it is relatively lower, thus better in comparison to the benchmark SPY (20.9%)
  • During the last 3 years, the volatility is 8.8%, which is smaller, thus better than the value of 17.3% from the benchmark.

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 volatility over 5 years of Enhanced Permanent Portfolio Strategy is 6.7%, which is lower, thus better compared to the benchmark SPY (15%) in the same period.
  • During the last 3 years, the downside deviation is 6.1%, which is smaller, thus better than the value of 12.1% 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:
  • Compared with the benchmark SPY (0.56) in the period of the last 5 years, the Sharpe Ratio of 0.81 of Enhanced Permanent Portfolio Strategy is higher, thus better.
  • Looking at Sharpe Ratio in of 0.24 in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (0.35).

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.'

Applying this definition to our asset in some examples:
  • Compared with the benchmark SPY (0.78) in the period of the last 5 years, the ratio of annual return and downside deviation of 1.16 of Enhanced Permanent Portfolio Strategy is greater, thus better.
  • During the last 3 years, the downside risk / excess return profile is 0.34, which is smaller, thus worse than the value of 0.5 from the benchmark.

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.'

Using this definition on our asset we see for example:
  • The Downside risk index over 5 years of Enhanced Permanent Portfolio Strategy is 4.61 , which is lower, thus better compared to the benchmark SPY (9.32 ) in the same period.
  • Compared with SPY (10 ) in the period of the last 3 years, the Ulcer Ratio of 5.65 is smaller, thus better.

MaxDD:

'Maximum drawdown measures the loss in any losing period during a fund’s investment record. It is defined as the percent retrenchment from a fund’s peak value to the fund’s valley value. The drawdown is in effect from the time the fund’s retrenchment begins until a new fund high is reached. The maximum drawdown encompasses both the period from the fund’s peak to the fund’s valley (length), and the time from the fund’s valley to a new fund high (recovery). It measures the largest percentage drawdown that has occurred in any fund’s data record.'

Applying this definition to our asset in some examples:
  • Compared with the benchmark SPY (-33.7 days) in the period of the last 5 years, the maximum drop from peak to valley of -14.9 days of Enhanced Permanent Portfolio Strategy is larger, thus better.
  • During the last 3 years, the maximum DrawDown is -14.9 days, which is higher, thus better than the value of -24.5 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.'

Applying this definition to our asset in some examples:
  • Compared with the benchmark SPY (488 days) in the period of the last 5 years, the maximum days below previous high of 564 days of Enhanced Permanent Portfolio Strategy is larger, thus worse.
  • Compared with SPY (488 days) in the period of the last 3 years, the maximum days below previous high of 564 days is higher, thus worse.

AveDuration:

'The Average Drawdown Duration is an extension of the Maximum Drawdown. However, this metric does not explain the drawdown in dollars or percentages, rather in days, weeks, or months. 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.'

Which means for our asset as example:
  • Compared with the benchmark SPY (123 days) in the period of the last 5 years, the average days under water of 153 days of Enhanced Permanent Portfolio Strategy is higher, thus worse.
  • Compared with SPY (180 days) in the period of the last 3 years, the average days below previous high of 228 days is higher, thus worse.
