Description

The Short Term Bond Strategy is essentially a place to park cash that earns interest. When combined with other higher risk strategies it creates a lower risk portfolio and generally improves the portfolio's Sharpe ratio. If your broker pays interest on cash balances that is comparable to the current yield of this strategy, you can choose to keep this allocation in cash instead.

Methodology & Assets

This strategy switches between very low risk ETFs that hold short term corporate or treasury bonds including GSY, MINT and NEAR.

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:
  • Compared with the benchmark SHY (5.5%) in the period of the last 5 years, the total return, or increase in value of 21.3% of Short Term Bond Strategy is larger, thus better.
  • Compared with SHY (1.3%) in the period of the last 3 years, the total return, or increase in value of 12.2% is higher, thus better.

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.'

Which means for our asset as example:
  • Looking at the annual performance (CAGR) of 3.9% in the last 5 years of Short Term Bond Strategy, we see it is relatively higher, thus better in comparison to the benchmark SHY (1.1%)
  • During the last 3 years, the annual performance (CAGR) is 3.9%, which is higher, thus better than the value of 0.4% from the benchmark.

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.'

Which means for our asset as example:
  • Compared with the benchmark SHY (1.9%) in the period of the last 5 years, the 30 days standard deviation of 2% of Short Term Bond Strategy is higher, thus worse.
  • Compared with SHY (2.3%) in the period of the last 3 years, the 30 days standard deviation of 1.2% 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.'

Which means for our asset as example:
  • Looking at the downside volatility of 1.6% in the last 5 years of Short Term Bond Strategy, we see it is relatively higher, thus worse in comparison to the benchmark SHY (1.2%)
  • During the last 3 years, the downside deviation is 0.8%, which is lower, thus better than the value of 1.5% from the benchmark.

Sharpe:

'The Sharpe ratio was developed by Nobel laureate William F. Sharpe, and is used to help investors understand the return of an investment compared to its risk. The ratio is the average return earned in excess of the risk-free rate per unit of volatility or total risk. Subtracting the risk-free rate from the mean return allows an investor to better isolate the profits associated with risk-taking activities. One intuition of this calculation is that a portfolio engaging in 'zero risk' investments, such as the purchase of U.S. Treasury bills (for which the expected return is the risk-free rate), has a Sharpe ratio of exactly zero. Generally, the greater the value of the Sharpe ratio, the more attractive the risk-adjusted return.'

Applying this definition to our asset in some examples:
  • Looking at the Sharpe Ratio of 0.72 in the last 5 years of Short Term Bond Strategy, we see it is relatively larger, thus better in comparison to the benchmark SHY (-0.76)
  • Compared with SHY (-0.92) in the period of the last 3 years, the Sharpe Ratio of 1.13 is higher, thus better.

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.'

Using this definition on our asset we see for example:
  • Compared with the benchmark SHY (-1.16) in the period of the last 5 years, the ratio of annual return and downside deviation of 0.89 of Short Term Bond Strategy is larger, thus better.
  • Compared with SHY (-1.38) in the period of the last 3 years, the downside risk / excess return profile of 1.82 is larger, thus better.

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.'

Which means for our asset as example:
  • Compared with the benchmark SHY (2.27 ) in the period of the last 5 years, the Ulcer Ratio of 0.52 of Short Term Bond Strategy is smaller, thus better.
  • Compared with SHY (2.93 ) in the period of the last 3 years, the Ulcer Ratio of 0.45 is lower, thus better.

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.'

Which means for our asset as example:
  • Compared with the benchmark SHY (-5.7 days) in the period of the last 5 years, the maximum drop from peak to valley of -5.2 days of Short Term Bond Strategy is larger, thus better.
  • During the last 3 years, the maximum drop from peak to valley is -2 days, which is higher, thus better than the value of -5.7 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.'

Using this definition on our asset we see for example:
  • Compared with the benchmark SHY (711 days) in the period of the last 5 years, the maximum days below previous high of 265 days of Short Term Bond Strategy is smaller, thus better.
  • During the last 3 years, the maximum days below previous high is 265 days, which is lower, thus better than the value of 711 days from the benchmark.

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.'

Applying this definition to our asset in some examples:
  • The average days under water over 5 years of Short Term Bond Strategy is 53 days, which is lower, thus better compared to the benchmark SHY (227 days) in the same period.
  • During the last 3 years, the average days under water is 78 days, which is smaller, thus better than the value of 346 days from the benchmark.
