Description

The investment seeks to track the investment results of the ICE U.S. Treasury 20+ Year Bond Index (the underlying index). The fund generally invests at least 90% of its assets in the bonds of the underlying index and at least 95% of its assets in U.S. government bonds. The underlying index measures the performance of public obligations of the U.S. Treasury that have a remaining maturity greater than or equal to twenty years.

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.'

Using this definition on our asset we see for example:
  • The total return, or increase in value over 5 years of iShares 20+ Year Treasury Bond ETF is -1%, which is lower, thus worse compared to the benchmark SPY (63%) in the same period.
  • Compared with SPY (33.5%) in the period of the last 3 years, the total return, or performance of -22.6% is lower, thus worse.

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:
  • Compared with the benchmark SPY (10.3%) in the period of the last 5 years, the annual performance (CAGR) of -0.2% of iShares 20+ Year Treasury Bond ETF is lower, thus worse.
  • During the last 3 years, the compounded annual growth rate (CAGR) is -8.2%, which is smaller, thus worse than the value of 10.1% 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.'

Applying this definition to our asset in some examples:
  • Compared with the benchmark SPY (21.6%) in the period of the last 5 years, the volatility of 16.3% of iShares 20+ Year Treasury Bond ETF is smaller, thus better.
  • Looking at volatility in of 19.1% in the period of the last 3 years, we see it is relatively smaller, thus better in comparison to SPY (25.1%).

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 SPY (15.6%) in the period of the last 5 years, the downside volatility of 11.3% of iShares 20+ Year Treasury Bond ETF is lower, thus better.
  • Looking at downside volatility in of 13.4% in the period of the last 3 years, we see it is relatively smaller, thus better in comparison to SPY (18.1%).

Sharpe:

'The Sharpe ratio (also known as the Sharpe index, the Sharpe measure, and the reward-to-variability ratio) is a way to examine the performance of an investment by adjusting for its risk. The ratio measures the excess return (or risk premium) per unit of deviation in an investment asset or a trading strategy, typically referred to as risk, named after William F. Sharpe.'

Which means for our asset as example:
  • The ratio of return and volatility (Sharpe) over 5 years of iShares 20+ Year Treasury Bond ETF is -0.17, which is lower, thus worse compared to the benchmark SPY (0.36) in the same period.
  • Looking at ratio of return and volatility (Sharpe) in of -0.56 in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (0.3).

Sortino:

'The Sortino ratio measures the risk-adjusted return of an investment asset, portfolio, or strategy. It is a modification of the Sharpe ratio but penalizes only those returns falling below a user-specified target or required rate of return, while the Sharpe ratio penalizes both upside and downside volatility equally. Though both ratios measure an investment's risk-adjusted return, they do so in significantly different ways that will frequently lead to differing conclusions as to the true nature of the investment's return-generating efficiency. The Sortino ratio is used as a way to compare the risk-adjusted performance of programs with differing risk and return profiles. In general, risk-adjusted returns seek to normalize the risk across programs and then see which has the higher return unit per risk.'

Which means for our asset as example:
  • The downside risk / excess return profile over 5 years of iShares 20+ Year Treasury Bond ETF is -0.24, which is lower, thus worse compared to the benchmark SPY (0.5) in the same period.
  • During the last 3 years, the ratio of annual return and downside deviation is -0.8, which is smaller, thus worse than the value of 0.42 from the benchmark.

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.'

Using this definition on our asset we see for example:
  • Looking at the Ulcer Index of 16 in the last 5 years of iShares 20+ Year Treasury Bond ETF, we see it is relatively greater, thus worse in comparison to the benchmark SPY (8.88 )
  • Looking at Downside risk index in of 21 in the period of the last 3 years, we see it is relatively larger, thus worse in comparison to SPY (11 ).

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.'

Applying this definition to our asset in some examples:
  • Compared with the benchmark SPY (-33.7 days) in the period of the last 5 years, the maximum reduction from previous high of -44.1 days of iShares 20+ Year Treasury Bond ETF is smaller, thus worse.
  • Compared with SPY (-33.7 days) in the period of the last 3 years, the maximum DrawDown of -44.1 days is lower, thus worse.

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:
  • The maximum days below previous high over 5 years of iShares 20+ Year Treasury Bond ETF is 630 days, which is larger, thus worse compared to the benchmark SPY (273 days) in the same period.
  • Looking at maximum days below previous high in of 630 days in the period of the last 3 years, we see it is relatively larger, thus worse in comparison to SPY (273 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.'

Which means for our asset as example:
  • Looking at the average days under water of 182 days in the last 5 years of iShares 20+ Year Treasury Bond ETF, we see it is relatively higher, thus worse in comparison to the benchmark SPY (57 days)
  • Looking at average time in days below previous high water mark in of 271 days in the period of the last 3 years, we see it is relatively larger, thus worse in comparison to SPY (73 days).
