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, when measuring performance, is the actual rate of return of an investment or a pool of investments over a given evaluation period. Total return includes interest, capital gains, dividends and distributions realized over a given period of time. Total return accounts for two categories of return: income including interest paid by fixed-income investments, distributions or dividends and capital appreciation, representing the change in the market price of an asset.'

Using this definition on our asset we see for example:
  • Looking at the total return of 23.3% in the last 5 years of Short Term Bond Strategy, we see it is relatively higher, thus better in comparison to the benchmark SHY (9.4%)
  • Compared with SHY (12.2%) in the period of the last 3 years, the total return, or performance of 16.4% is greater, thus better.

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.'

Using this definition on our asset we see for example:
  • The annual performance (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 compounded annual growth rate (CAGR) in of 5.2% in the period of the last 3 years, we see it is relatively higher, thus better in comparison to SHY (3.9%).

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:
  • Looking at the historical 30 days volatility of 1% in the last 5 years of Short Term Bond Strategy, we see it is relatively lower, thus better in comparison to the benchmark SHY (2%)
  • During the last 3 years, the volatility is 0.5%, which is smaller, thus better than the value of 1.6% 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:
  • Compared with the benchmark SHY (1.3%) in the period of the last 5 years, the downside deviation of 0.6% of Short Term Bond Strategy is lower, thus better.
  • Looking at downside deviation 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:
  • The ratio of return and volatility (Sharpe) over 5 years of Short Term Bond Strategy is 1.88, which is higher, thus better compared to the benchmark SHY (-0.34) in the same period.
  • Compared with SHY (0.87) in the period of the last 3 years, the risk / return profile (Sharpe) of 5.23 is larger, thus better.

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.'

Which means for our asset as example:
  • Looking at the downside risk / excess return profile of 3.09 in the last 5 years of Short Term Bond Strategy, we see it is relatively greater, thus better in comparison to the benchmark SHY (-0.52)
  • 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 (1.41).

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 lower, thus better compared to the benchmark SHY (2.14 ) in the same period.
  • During the last 3 years, the Ulcer Ratio 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.'

Using this definition on our asset we see for example:
  • Looking at the maximum reduction from previous high of -2 days in the last 5 years of Short Term Bond Strategy, we see it is relatively larger, thus better in comparison to the benchmark SHY (-5.5 days)
  • Looking at maximum reduction from previous high in of -0.2 days in the period of the last 3 years, we see it is relatively higher, 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). Many assume Max DD Duration is the length of time between new highs during which the Max DD (magnitude) occurred. But that isn’t always the case. The Max DD duration is the longest time between peaks, period. So it could be the time when the program also had its biggest peak to valley loss (and usually is, because the program needs a long time to recover from the largest loss), but it doesn’t have to be'

Which means for our asset as 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 (580 days)
  • Looking at maximum days under water in of 17 days in the period of the last 3 years, we see it is relatively lower, thus better in comparison to SHY (93 days).

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.'

Using this definition on our asset we see for example:
  • Looking at the average days below previous high of 65 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 (161 days)
  • Looking at average days under water in of 3 days in the period of the last 3 years, we see it is relatively smaller, thus better in comparison to SHY (21 days).
