'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.'

Which means for our asset as example:- Compared with the benchmark SPY (61.3%) in the period of the last 5 years, the total return, or performance of -7.2% of iShares 20+ Year Treasury Bond ETF is smaller, thus worse.
- Looking at total return, or increase in value in of -23.1% in the period of the last 3 years, we see it is relatively smaller, thus worse in comparison to SPY (31.6%).

'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:- Looking at the compounded annual growth rate (CAGR) of -1.5% in the last 5 years of iShares 20+ Year Treasury Bond ETF, we see it is relatively smaller, thus worse in comparison to the benchmark SPY (10%)
- Compared with SPY (9.6%) in the period of the last 3 years, the compounded annual growth rate (CAGR) of -8.4% is smaller, thus worse.

'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:- Compared with the benchmark SPY (20.8%) in the period of the last 5 years, the volatility of 15.5% of iShares 20+ Year Treasury Bond ETF is smaller, thus better.
- During the last 3 years, the 30 days standard deviation is 18.2%, which is lower, thus better than the value of 24% 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.'

Which means for our asset as example:- Looking at the downside deviation of 11% 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 (15.3%)
- During the last 3 years, the downside deviation is 12.9%, which is lower, thus better than the value of 17.6% from the benchmark.

'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.'

Using this definition on our asset we see for example:- Looking at the ratio of return and volatility (Sharpe) of -0.26 in the last 5 years of iShares 20+ Year Treasury Bond ETF, we see it is relatively lower, thus worse in comparison to the benchmark SPY (0.36)
- During the last 3 years, the risk / return profile (Sharpe) is -0.6, which is lower, thus worse than the value of 0.3 from the benchmark.

'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:- Looking at the excess return divided by the downside deviation of -0.36 in the last 5 years of iShares 20+ Year Treasury Bond ETF, we see it is relatively smaller, thus worse in comparison to the benchmark SPY (0.49)
- Looking at ratio of annual return and downside deviation in of -0.84 in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (0.4).

'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 13 in the last 5 years of iShares 20+ Year Treasury Bond ETF, we see it is relatively larger, thus worse in comparison to the benchmark SPY (7.61 )
- Looking at Ulcer Ratio in of 16 in the period of the last 3 years, we see it is relatively larger, thus worse in comparison to SPY (8.93 ).

'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:- Compared with the benchmark SPY (-33.7 days) in the period of the last 5 years, the maximum drop from peak to valley of -39.1 days of iShares 20+ Year Treasury Bond ETF is lower, thus worse.
- Compared with SPY (-33.7 days) in the period of the last 3 years, the maximum drop from peak to valley of -39.1 days is smaller, thus worse.

'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 below previous high over 5 years of iShares 20+ Year Treasury Bond ETF is 542 days, which is larger, thus worse compared to the benchmark SPY (185 days) in the same period.
- Compared with SPY (185 days) in the period of the last 3 years, the maximum days under water of 542 days is greater, thus worse.

'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.'

Applying this definition to our asset in some examples:- Compared with the benchmark SPY (46 days) in the period of the last 5 years, the average time in days below previous high water mark of 173 days of iShares 20+ Year Treasury Bond ETF is greater, thus worse.
- During the last 3 years, the average time in days below previous high water mark is 208 days, which is greater, thus worse than the value of 44 days from the benchmark.
