'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:- Compared with the benchmark SPY (110.8%) in the period of the last 5 years, the total return, or increase in value of 20.8% of iShares 20+ Year Treasury Bond ETF is smaller, thus worse.
- Looking at total return, or performance in of 25% in the period of the last 3 years, we see it is relatively smaller, thus worse in comparison to SPY (50.8%).

'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.'

Using this definition on our asset we see for example:- Compared with the benchmark SPY (16.1%) in the period of the last 5 years, the annual return (CAGR) of 3.9% of iShares 20+ Year Treasury Bond ETF is lower, thus worse.
- During the last 3 years, the annual return (CAGR) is 7.7%, which is smaller, thus worse than the value of 14.7% from the benchmark.

'In finance, volatility (symbol σ) is the degree of variation of a trading price series over time as measured by the standard deviation of logarithmic returns. Historic volatility measures a time series of past market prices. Implied volatility looks forward in time, being derived from the market price of a market-traded derivative (in particular, an option). Commonly, the higher the volatility, the riskier the security.'

Using this definition on our asset we see for example:- The historical 30 days volatility over 5 years of iShares 20+ Year Treasury Bond ETF is 13.8%, which is lower, thus better compared to the benchmark SPY (18.7%) in the same period.
- During the last 3 years, the 30 days standard deviation is 15.4%, which is lower, thus better than the value of 22.7% from the benchmark.

'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:- Looking at the downside volatility of 9.6% in the last 5 years of iShares 20+ Year Treasury Bond ETF, we see it is relatively lower, thus better in comparison to the benchmark SPY (13.6%)
- Compared with SPY (16.5%) in the period of the last 3 years, the downside deviation of 10.4% is lower, thus better.

'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:- Compared with the benchmark SPY (0.73) in the period of the last 5 years, the ratio of return and volatility (Sharpe) of 0.1 of iShares 20+ Year Treasury Bond ETF is lower, thus worse.
- Looking at risk / return profile (Sharpe) in of 0.34 in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (0.54).

'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 SPY (1) in the period of the last 5 years, the downside risk / excess return profile of 0.14 of iShares 20+ Year Treasury Bond ETF is smaller, thus worse.
- Compared with SPY (0.74) in the period of the last 3 years, the excess return divided by the downside deviation of 0.5 is smaller, thus worse.

'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.'

Applying this definition to our asset in some examples:- The Ulcer Ratio over 5 years of iShares 20+ Year Treasury Bond ETF is 9.57 , which is higher, thus worse compared to the benchmark SPY (5.58 ) in the same period.
- Compared with SPY (6.91 ) in the period of the last 3 years, the Downside risk index of 5.09 is smaller, thus better.

'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:- Looking at the maximum drop from peak to valley of -18.7 days in the last 5 years of iShares 20+ Year Treasury Bond ETF, we see it is relatively larger, thus better in comparison to the benchmark SPY (-33.7 days)
- Compared with SPY (-33.7 days) in the period of the last 3 years, the maximum drop from peak to valley of -18.7 days is larger, thus better.

'The Drawdown Duration is the length of any peak to peak period, or the time between new equity highs. The Max Drawdown Duration is the worst (the maximum/longest) amount of time an investment has seen between peaks (equity highs). Many assume Max DD Duration is the length of time between new highs during which the Max DD (magnitude) occurred. But that isn’t always the case. The Max DD duration is the longest time between peaks, period. So it could be the time when the program also had its biggest peak to valley loss (and usually is, because the program needs a long time to recover from the largest loss), but it doesn’t have to be'

Which means for our asset as example:- The maximum days under water over 5 years of iShares 20+ Year Treasury Bond ETF is 749 days, which is larger, thus worse compared to the benchmark SPY (139 days) in the same period.
- Compared with SPY (139 days) in the period of the last 3 years, the maximum days below previous high of 147 days is greater, thus worse.

'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.'

Using this definition on our asset we see for example:- Looking at the average time in days below previous high water mark of 249 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 (33 days)
- Compared with SPY (36 days) in the period of the last 3 years, the average time in days below previous high water mark of 44 days is greater, thus worse.
