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.'

Which means for our asset as example:
  • Looking at the total return, or performance of 23.2% in the last 5 years of Short Term Bond Strategy, we see it is relatively larger, thus better in comparison to the benchmark SHY (9.4%)
  • Looking at total return, or increase in value in of 16.5% in the period of the last 3 years, we see it is relatively larger, thus better in comparison to SHY (12.5%).

CAGR:

'The compound annual growth rate isn't a true return rate, but rather a representational figure. It is essentially a number that describes the rate at which an investment would have grown if it had grown the same rate every year and the profits were reinvested at the end of each year. In reality, this sort of performance is unlikely. However, CAGR can be used to smooth returns so that they may be more easily understood when compared to alternative investments.'

Which means for our asset as example:
  • The compounded annual growth rate (CAGR) over 5 years of Short Term Bond Strategy is 4.3%, which is larger, thus better compared to the benchmark SHY (1.8%) in the same period.
  • Looking at annual return (CAGR) in of 5.2% in the period of the last 3 years, we see it is relatively greater, thus better in comparison to SHY (4%).

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 30 days standard deviation over 5 years of Short Term Bond Strategy is 1%, which is lower, thus better compared to the benchmark SHY (2%) in the same period.
  • Looking at 30 days standard deviation in of 0.5% in the period of the last 3 years, we see it is relatively lower, thus better in comparison to SHY (1.6%).

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 Short Term Bond Strategy is 0.6%, which is smaller, thus better compared to the benchmark SHY (1.3%) in the same period.
  • Looking at downside volatility in of 0.2% in the period of the last 3 years, we see it is relatively lower, thus better in comparison to SHY (1%).

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.'

Using this definition on our asset we see for example:
  • Looking at the risk / return profile (Sharpe) of 1.87 in the last 5 years of Short Term Bond Strategy, we see it is relatively higher, thus better in comparison to the benchmark SHY (-0.34)
  • During the last 3 years, the Sharpe Ratio is 5.25, which is larger, thus better than the value of 0.93 from the benchmark.

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:
  • Looking at the downside risk / excess return profile of 3.08 in the last 5 years of Short Term Bond Strategy, we see it is relatively larger, thus better in comparison to the benchmark SHY (-0.52)
  • During the last 3 years, the excess return divided by the downside deviation is 13, which is higher, thus better than the value of 1.51 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 Short Term Bond Strategy is 0.35 , which is smaller, thus better compared to the benchmark SHY (2.14 ) in the same period.
  • During the last 3 years, the Downside risk index is 0.03 , which is lower, thus better than the value of 0.32 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:
  • Looking at the maximum drop from peak to valley of -2 days in the last 5 years of Short Term Bond Strategy, we see it is relatively greater, thus better in comparison to the benchmark SHY (-5.5 days)
  • Looking at maximum DrawDown in of -0.2 days in the period of the last 3 years, we see it is relatively larger, thus better in comparison to SHY (-1 days).

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 time in days below previous high water mark of 265 days in the last 5 years of Short Term Bond Strategy, we see it is relatively smaller, thus better in comparison to the benchmark SHY (580 days)
  • During the last 3 years, the maximum time in days below previous high water mark is 17 days, which is lower, thus better than the value of 93 days from the benchmark.

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.'

Applying this definition to our asset in some examples:
  • Compared with the benchmark SHY (161 days) in the period of the last 5 years, the average time in days below previous high water mark of 65 days of Short Term Bond Strategy is smaller, thus better.
  • Compared with SHY (21 days) in the period of the last 3 years, the average time in days below previous high water mark of 3 days is lower, thus better.
