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.'

Which means for our asset as example:
  • Compared with the benchmark SHY (6.4%) in the period of the last 5 years, the total return, or increase in value of 22.8% of Short Term Bond Strategy is larger, thus better.
  • Looking at total return, or increase in value in of 14.2% in the period of the last 3 years, we see it is relatively larger, thus better in comparison to SHY (4.6%).

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 Short Term Bond Strategy is 4.2%, which is higher, thus better compared to the benchmark SHY (1.2%) in the same period.
  • During the last 3 years, the annual return (CAGR) is 4.5%, which is higher, thus better than the value of 1.5% 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.'

Using this definition on our asset we see for example:
  • Looking at the 30 days standard deviation of 2% in the last 5 years of Short Term Bond Strategy, we see it is relatively larger, thus worse in comparison to the benchmark SHY (1.9%)
  • Compared with SHY (2.3%) in the period of the last 3 years, the volatility of 1% is smaller, thus better.

DownVol:

'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.'

Applying this definition to our asset in some examples:
  • Compared with the benchmark SHY (1.2%) in the period of the last 5 years, the downside volatility of 1.6% of Short Term Bond Strategy is higher, thus worse.
  • Compared with SHY (1.5%) in the period of the last 3 years, the downside volatility of 0.5% is smaller, thus better.

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 0.85 in the last 5 years of Short Term Bond Strategy, we see it is relatively greater, thus better in comparison to the benchmark SHY (-0.65)
  • During the last 3 years, the ratio of return and volatility (Sharpe) is 2.15, which is larger, thus better than the value of -0.42 from the benchmark.

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:
  • The ratio of annual return and downside deviation over 5 years of Short Term Bond Strategy is 1.06, which is greater, thus better compared to the benchmark SHY (-1.01) in the same period.
  • During the last 3 years, the downside risk / excess return profile is 4.09, which is greater, thus better than the value of -0.64 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.'

Which means for our asset as example:
  • Compared with the benchmark SHY (2.28 ) in the period of the last 5 years, the Ulcer Index of 0.52 of Short Term Bond Strategy is smaller, thus better.
  • Compared with SHY (2.06 ) in the period of the last 3 years, the Ulcer Index of 0.31 is lower, thus better.

MaxDD:

'Maximum drawdown measures the loss in any losing period during a fund’s investment record. It is defined as the percent retrenchment from a fund’s peak value to the fund’s valley value. The drawdown is in effect from the time the fund’s retrenchment begins until a new fund high is reached. The maximum drawdown encompasses both the period from the fund’s peak to the fund’s valley (length), and the time from the fund’s valley to a new fund high (recovery). It measures the largest percentage drawdown that has occurred in any fund’s data record.'

Using this definition on our asset we see for 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 greater, thus better.
  • During the last 3 years, the maximum drop from peak to valley is -1 days, which is higher, thus better than the value of -4.6 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.'

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 lower, thus better in comparison to the benchmark SHY (711 days)
  • Looking at maximum days below previous high in of 195 days in the period of the last 3 years, we see it is relatively lower, thus better in comparison to SHY (474 days).

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:
  • The average days under water over 5 years of Short Term Bond Strategy is 53 days, which is smaller, thus better compared to the benchmark SHY (228 days) in the same period.
  • Looking at average days under water in of 50 days in the period of the last 3 years, we see it is relatively lower, thus better in comparison to SHY (168 days).
