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, or performance of 25.1% 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%)
  • Compared with SHY (13.6%) in the period of the last 3 years, the total return of 17.6% is higher, thus better.

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 4.6%, which is greater, thus better compared to the benchmark SHY (1.7%) in the same period.
  • Compared with SHY (4.4%) in the period of the last 3 years, the compounded annual growth rate (CAGR) of 5.6% is higher, thus better.

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 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 (2%)
  • Looking at volatility in of 0.6% in the period of the last 3 years, we see it is relatively smaller, thus better in comparison to SHY (2%).

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:
  • Looking at the downside risk of 0.7% in the last 5 years of Short Term Bond Strategy, we see it is relatively lower, thus better in comparison to the benchmark SHY (1.3%)
  • During the last 3 years, the downside risk is 0.2%, which is smaller, thus better than the value of 1.2% 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 1.81 in the last 5 years of Short Term Bond Strategy, we see it is relatively larger, thus better in comparison to the benchmark SHY (-0.39)
  • During the last 3 years, the ratio of return and volatility (Sharpe) is 5.42, which is larger, thus better than the value of 0.96 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.'

Using this definition on our asset we see for example:
  • Compared with the benchmark SHY (-0.6) in the period of the last 5 years, the excess return divided by the downside deviation of 2.9 of Short Term Bond Strategy is higher, thus better.
  • Looking at excess return divided by the downside deviation in of 13 in the period of the last 3 years, we see it is relatively greater, thus better in comparison to SHY (1.62).

Ulcer:

'The ulcer index is a stock market risk measure or technical analysis indicator devised by Peter Martin in 1987, and published by him and Byron McCann in their 1989 book The Investors Guide to Fidelity Funds. It's designed as a measure of volatility, but only volatility in the downward direction, i.e. the amount of drawdown or retracement occurring over a period. Other volatility measures like standard deviation treat up and down movement equally, but a trader doesn't mind upward movement, it's the downside that causes stress and stomach ulcers that the index's name suggests.'

Applying this definition to our asset in some examples:
  • 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 smaller, thus better.
  • Compared with SHY (0.47 ) in the period of the last 3 years, the Downside risk index of 0.03 is lower, thus better.

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 DrawDown of -2 days of Short Term Bond Strategy is greater, thus better.
  • During the last 3 years, the maximum DrawDown is -0.2 days, which is greater, 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.'

Which means for our asset as example:
  • Compared with the benchmark SHY (712 days) in the period of the last 5 years, the maximum days below previous high of 265 days of Short Term Bond Strategy is smaller, thus better.
  • During the last 3 years, the maximum days under water is 10 days, which is smaller, thus better than the value of 126 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.'

Which means for our asset as example:
  • Compared with the benchmark SHY (232 days) in the period of the last 5 years, the average days below previous high of 59 days of Short Term Bond Strategy is lower, thus better.
  • Looking at average time in days below previous high water mark in of 2 days in the period of the last 3 years, we see it is relatively lower, thus better in comparison to SHY (27 days).
