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 is the amount of value an investor earns from a security over a specific period, typically one year, when all distributions are reinvested. Total return is expressed as a percentage of the amount invested. For example, a total return of 20% means the security increased by 20% of its original value due to a price increase, distribution of dividends (if a stock), coupons (if a bond) or capital gains (if a fund). Total return is a strong measure of an investment’s overall performance.'

Using this definition on our asset we see for example:
  • Looking at the total return, or increase in value of 60.6% in the last 5 years of Enhanced Permanent Portfolio Strategy, we see it is relatively lower, thus worse in comparison to the benchmark SPY (82.8%)
  • Compared with SPY (80.4%) in the period of the last 3 years, the total return of 67.8% is lower, thus worse.

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.'

Using this definition on our asset we see for example:
  • The compounded annual growth rate (CAGR) over 5 years of Enhanced Permanent Portfolio Strategy is 10%, which is lower, thus worse compared to the benchmark SPY (12.9%) in the same period.
  • During the last 3 years, the annual performance (CAGR) is 18.9%, which is lower, thus worse than the value of 21.8% from the benchmark.

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.'

Which means for our asset as example:
  • The 30 days standard deviation over 5 years of Enhanced Permanent Portfolio Strategy is 9.6%, which is smaller, thus better compared to the benchmark SPY (17.2%) in the same period.
  • Looking at historical 30 days volatility in of 9.9% in the period of the last 3 years, we see it is relatively smaller, thus better in comparison to SPY (15.3%).

DownVol:

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

Applying this definition to our asset in some examples:
  • The downside deviation over 5 years of Enhanced Permanent Portfolio Strategy is 6.7%, which is smaller, thus better compared to the benchmark SPY (11.8%) in the same period.
  • Compared with SPY (10.2%) in the period of the last 3 years, the downside deviation of 6.9% is lower, thus better.

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.'

Which means for our asset as example:
  • Compared with the benchmark SPY (0.6) in the period of the last 5 years, the ratio of return and volatility (Sharpe) of 0.78 of Enhanced Permanent Portfolio Strategy is larger, thus better.
  • Looking at Sharpe Ratio in of 1.65 in the period of the last 3 years, we see it is relatively greater, thus better in comparison to SPY (1.26).

Sortino:

'The Sortino ratio, a variation of the Sharpe ratio only factors in the downside, or negative volatility, rather than the total volatility used in calculating the Sharpe ratio. The theory behind the Sortino variation is that upside volatility is a plus for the investment, and it, therefore, should not be included in the risk calculation. Therefore, the Sortino ratio takes upside volatility out of the equation and uses only the downside standard deviation in its calculation instead of the total standard deviation that is used in calculating the Sharpe ratio.'

Which means for our asset as example:
  • The downside risk / excess return profile over 5 years of Enhanced Permanent Portfolio Strategy is 1.11, which is larger, thus better compared to the benchmark SPY (0.88) in the same period.
  • Compared with SPY (1.89) in the period of the last 3 years, the excess return divided by the downside deviation of 2.39 is higher, thus better.

Ulcer:

'The Ulcer Index is a technical indicator that measures downside risk, in terms of both the depth and duration of price declines. The index increases in value as the price moves farther away from a recent high and falls as the price rises to new highs. The indicator is usually calculated over a 14-day period, with the Ulcer Index showing the percentage drawdown a trader can expect from the high over that period. The greater the value of the Ulcer Index, the longer it takes for a stock to get back to the former high.'

Which means for our asset as example:
  • Compared with the benchmark SPY (8.45 ) in the period of the last 5 years, the Ulcer Ratio of 4.94 of Enhanced Permanent Portfolio Strategy is lower, thus better.
  • Looking at Ulcer Ratio in of 3.03 in the period of the last 3 years, we see it is relatively lower, thus better in comparison to SPY (3.37 ).

MaxDD:

'Maximum drawdown is defined as the peak-to-trough decline of an investment during a specific period. It is usually quoted as a percentage of the peak value. The maximum drawdown can be calculated based on absolute returns, in order to identify strategies that suffer less during market downturns, such as low-volatility strategies. However, the maximum drawdown can also be calculated based on returns relative to a benchmark index, for identifying strategies that show steady outperformance over time.'

Applying this definition to our asset in some examples:
  • Looking at the maximum DrawDown of -14.9 days in the last 5 years of Enhanced Permanent Portfolio Strategy, we see it is relatively larger, thus better in comparison to the benchmark SPY (-24.5 days)
  • Compared with SPY (-18.8 days) in the period of the last 3 years, the maximum drop from peak to valley of -10.5 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.'

Using this definition on our asset we see for example:
  • The maximum time in days below previous high water mark over 5 years of Enhanced Permanent Portfolio Strategy is 564 days, which is greater, thus worse compared to the benchmark SPY (488 days) in the same period.
  • Compared with SPY (87 days) in the period of the last 3 years, the maximum days under water of 146 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:
  • Looking at the average days below previous high of 156 days in the last 5 years of Enhanced Permanent Portfolio Strategy, we see it is relatively greater, thus worse in comparison to the benchmark SPY (118 days)
  • During the last 3 years, the average days below previous high is 26 days, which is higher, thus worse than the value of 18 days from the benchmark.
