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:

'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, or performance over 5 years of Short Term Bond Strategy is 24.8%, which is larger, thus better compared to the benchmark SHY (8.4%) in the same period.
  • During the last 3 years, the total return is 17.5%, which is higher, thus better than the value of 12.8% from the benchmark.

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:
  • The annual return (CAGR) over 5 years of Short Term Bond Strategy is 4.6%, which is higher, thus better compared to the benchmark SHY (1.6%) in the same period.
  • During the last 3 years, the compounded annual growth rate (CAGR) is 5.6%, which is greater, thus better than the value of 4.1% 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.'

Using this definition on our asset we see for example:
  • Looking at the 30 days standard deviation of 1.2% in the last 5 years of Short Term Bond Strategy, we see it is relatively smaller, thus better in comparison to the benchmark SHY (1.9%)
  • Compared with SHY (2%) in the period of the last 3 years, the 30 days standard deviation of 0.6% is lower, 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:
  • Looking at the downside volatility of 0.8% in the last 5 years of Short Term Bond Strategy, we see it is relatively smaller, thus better in comparison to the benchmark SHY (1.3%)
  • Looking at downside volatility in of 0.2% in the period of the last 3 years, we see it is relatively smaller, thus better in comparison to SHY (1.2%).

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.'

Applying this definition to our asset in some examples:
  • Looking at the ratio of return and volatility (Sharpe) of 1.67 in the last 5 years of Short Term Bond Strategy, we see it is relatively greater, thus better in comparison to the benchmark SHY (-0.44)
  • Compared with SHY (0.8) in the period of the last 3 years, the risk / return profile (Sharpe) of 5.28 is larger, 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:
  • The ratio of annual return and downside deviation over 5 years of Short Term Bond Strategy is 2.62, which is greater, thus better compared to the benchmark SHY (-0.69) in the same period.
  • Looking at excess return divided by the downside deviation in of 12 in the period of the last 3 years, we see it is relatively higher, thus better in comparison to SHY (1.33).

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 (2.29 ) in the period of the last 5 years, the Ulcer Ratio of 0.36 of Short Term Bond Strategy is lower, thus better.
  • During the last 3 years, the Ulcer Index is 0.03 , which is lower, thus better than the value of 0.5 from the benchmark.

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:
  • Compared with the benchmark SHY (-5.7 days) in the period of the last 5 years, the maximum drop from peak to valley of -2 days of Short Term Bond Strategy is larger, thus better.
  • During the last 3 years, the maximum DrawDown is -0.2 days, which is higher, thus better than the value of -1.6 days from the benchmark.

MaxDuration:

'The Maximum 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. It is the length of time the account was in the Max Drawdown. A Max Drawdown measures a retrenchment from when an equity curve reaches a new high. It’s the maximum an account lost during that retrenchment. This method is applied because a valley can’t be measured until a new high occurs. Once the new high is reached, the percentage change from the old high to the bottom of the largest trough is recorded.'

Using this definition on our asset we see for example:
  • Looking at the maximum days under water of 265 days in the last 5 years of Short Term Bond Strategy, we see it is relatively lower, thus better in comparison to the benchmark SHY (712 days)
  • During the last 3 years, the maximum time in days below previous high water mark is 10 days, which is lower, thus better than the value of 126 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.'

Which means for our asset as example:
  • The average time in days below previous high water mark over 5 years of Short Term Bond Strategy is 58 days, which is lower, thus better compared to the benchmark SHY (231 days) in the same period.
  • Compared with SHY (26 days) in the period of the last 3 years, the average days below previous high of 2 days is lower, thus better.
