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 increase in value of 24.3% in the last 5 years of Short Term Bond Strategy, we see it is relatively larger, thus better in comparison to the benchmark SHY (5.3%)
  • During the last 3 years, the total return, or performance is 15.3%, which is higher, thus better than the value of 9.2% 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 performance (CAGR) over 5 years of Short Term Bond Strategy is 4.5%, which is larger, thus better compared to the benchmark SHY (1%) in the same period.
  • During the last 3 years, the compounded annual growth rate (CAGR) is 4.9%, which is larger, thus better than the value of 3% 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:
  • Looking at the historical 30 days volatility of 1.2% in the last 5 years of Short Term Bond Strategy, we see it is relatively lower, thus better in comparison to the benchmark SHY (1.9%)
  • Looking at 30 days standard deviation in of 0.6% in the period of the last 3 years, we see it is relatively lower, thus better in comparison to SHY (2.3%).

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:
  • The downside risk over 5 years of Short Term Bond Strategy is 0.8%, which is lower, thus better compared to the benchmark SHY (1.2%) in the same period.
  • During the last 3 years, the downside deviation is 0.3%, which is lower, thus better than the value of 1.4% 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.'

Using this definition on our asset we see for example:
  • Looking at the Sharpe Ratio of 1.58 in the last 5 years of Short Term Bond Strategy, we see it is relatively higher, thus better in comparison to the benchmark SHY (-0.77)
  • Compared with SHY (0.22) in the period of the last 3 years, the Sharpe Ratio of 3.74 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.'

Which means for our asset as example:
  • The excess return divided by the downside deviation over 5 years of Short Term Bond Strategy is 2.48, which is greater, thus better compared to the benchmark SHY (-1.17) in the same period.
  • Looking at excess return divided by the downside deviation in of 7.83 in the period of the last 3 years, we see it is relatively larger, thus better in comparison to SHY (0.35).

Ulcer:

'The Ulcer Index is a technical indicator that measures downside risk, in terms of both the depth and duration of price declines. The index increases in value as the price moves farther away from a recent high and falls as the price rises to new highs. The indicator is usually calculated over a 14-day period, with the Ulcer Index showing the percentage drawdown a trader can expect from the high over that period. The greater the value of the Ulcer Index, the longer it takes for a stock to get back to the former high.'

Which means for our asset as example:
  • The Ulcer Index over 5 years of Short Term Bond Strategy is 0.36 , which is lower, thus better compared to the benchmark SHY (2.29 ) in the same period.
  • During the last 3 years, the Ulcer Ratio is 0.09 , which is smaller, thus better than the value of 0.93 from the benchmark.

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:
  • The maximum drop from peak to valley over 5 years of Short Term Bond Strategy is -2 days, which is larger, thus better compared to the benchmark SHY (-5.7 days) in the same period.
  • During the last 3 years, the maximum drop from peak to valley is -0.4 days, which is larger, thus better than the value of -2.8 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:
  • The maximum days below previous high over 5 years of Short Term Bond Strategy is 265 days, which is lower, thus better compared to the benchmark SHY (712 days) in the same period.
  • During the last 3 years, the maximum days below previous high is 54 days, which is smaller, thus better than the value of 200 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 54 days, which is lower, thus better compared to the benchmark SHY (230 days) in the same period.
  • During the last 3 years, the average time in days below previous high water mark is 11 days, which is lower, thus better than the value of 53 days from the benchmark.
