Statistics of iShares Short Maturity Bond ETF (YTD)

What do these metrics mean? [Read More] [Hide]

TotalReturn:

'The total return on a portfolio of investments takes into account not only the capital appreciation on the portfolio, but also the income received on the portfolio. The income typically consists of interest, dividends, and securities lending fees. This contrasts with the price return, which takes into account only the capital gain on an investment.'

Applying this definition to our asset in some examples:
  • Looking at the total return of 8% in the last 5 years of iShares Short Maturity Bond ETF, we see it is relatively lower, thus worse in comparison to the benchmark SPY (64.1%)
  • Looking at total return, or performance in of 6.2% in the period of the last 3 years, we see it is relatively smaller, thus worse in comparison to SPY (48.1%).

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.'

Applying this definition to our asset in some examples:
  • The annual return (CAGR) over 5 years of iShares Short Maturity Bond ETF is 1.6%, which is lower, thus worse compared to the benchmark SPY (10.4%) in the same period.
  • During the last 3 years, the compounded annual growth rate (CAGR) is 2%, which is lower, thus worse than the value of 14% 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.'

Which means for our asset as example:
  • Looking at the volatility of 0.6% in the last 5 years of iShares Short Maturity Bond ETF, we see it is relatively lower, thus better in comparison to the benchmark SPY (13.6%)
  • Compared with SPY (12.8%) in the period of the last 3 years, the 30 days standard deviation of 0.5% is lower, 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.'

Using this definition on our asset we see for example:
  • Compared with the benchmark SPY (14.9%) in the period of the last 5 years, the downside volatility of 0.8% of iShares Short Maturity Bond ETF is smaller, thus better.
  • Looking at downside deviation in of 0.7% in the period of the last 3 years, we see it is relatively lower, thus better in comparison to SPY (14.5%).

Sharpe:

'The Sharpe ratio is the measure of risk-adjusted return of a financial portfolio. Sharpe ratio is a measure of excess portfolio return over the risk-free rate relative to its standard deviation. Normally, the 90-day Treasury bill rate is taken as the proxy for risk-free rate. A portfolio with a higher Sharpe ratio is considered superior relative to its peers. The measure was named after William F Sharpe, a Nobel laureate and professor of finance, emeritus at Stanford University.'

Using this definition on our asset we see for example:
  • The risk / return profile (Sharpe) over 5 years of iShares Short Maturity Bond ETF is -1.6, which is lower, thus worse compared to the benchmark SPY (0.58) in the same period.
  • During the last 3 years, the Sharpe Ratio is -1.02, which is lower, thus worse than the value of 0.9 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:
  • Compared with the benchmark SPY (0.53) in the period of the last 5 years, the excess return divided by the downside deviation of -1.15 of iShares Short Maturity Bond ETF is lower, thus worse.
  • During the last 3 years, the downside risk / excess return profile is -0.68, which is lower, thus worse than the value of 0.79 from the benchmark.

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.'

Using this definition on our asset we see for example:
  • Looking at the Ulcer Ratio of 0.06 in the last 5 years of iShares Short Maturity Bond ETF, we see it is relatively smaller, thus better in comparison to the benchmark SPY (4.02 )
  • During the last 3 years, the Ulcer Ratio is 0.03 , which is lower, thus better than the value of 4.09 from the benchmark.

MaxDD:

'A maximum drawdown is the maximum loss from a peak to a trough of a portfolio, before a new peak is attained. Maximum Drawdown is an indicator of downside risk over a specified time period. It can be used both as a stand-alone measure or as an input into other metrics such as 'Return over Maximum Drawdown' and the Calmar Ratio. Maximum Drawdown is expressed in percentage terms.'

Which means for our asset as example:
  • The maximum DrawDown over 5 years of iShares Short Maturity Bond ETF is -0.3 days, which is larger, thus better compared to the benchmark SPY (-19.3 days) in the same period.
  • Looking at maximum DrawDown in of -0.2 days in the period of the last 3 years, we see it is relatively higher, thus better in comparison to SPY (-19.3 days).

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.'

Using this definition on our asset we see for example:
  • Looking at the maximum days below previous high of 89 days in the last 5 years of iShares Short Maturity Bond ETF, we see it is relatively smaller, thus better in comparison to the benchmark SPY (187 days)
  • Looking at maximum days below previous high in of 29 days in the period of the last 3 years, we see it is relatively lower, thus better in comparison to SPY (139 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 below previous high over 5 years of iShares Short Maturity Bond ETF is 10 days, which is lower, thus better compared to the benchmark SPY (41 days) in the same period.
  • During the last 3 years, the average days below previous high is 5 days, which is smaller, thus better than the value of 35 days from the benchmark.
