'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.'

Which means for our asset as example:- Looking at the total return of 8.7% in the last 5 years of iShares 1-3 Year Treasury Bond ETF, we see it is relatively smaller, thus worse in comparison to the benchmark SPY (72.5%)
- Compared with SPY (34.1%) in the period of the last 3 years, the total return, or increase in value of 7.7% is lower, thus worse.

'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 annual performance (CAGR) of 1.7% in the last 5 years of iShares 1-3 Year Treasury Bond ETF, we see it is relatively smaller, thus worse in comparison to the benchmark SPY (11.5%)
- Looking at compounded annual growth rate (CAGR) in of 2.5% in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (10.3%).

'Volatility is a rate at which the price of a security increases or decreases for a given set of returns. Volatility is measured by calculating the standard deviation of the annualized returns over a given period of time. It shows the range to which the price of a security may increase or decrease. Volatility measures the risk of a security. It is used in option pricing formula to gauge the fluctuations in the returns of the underlying assets. Volatility indicates the pricing behavior of the security and helps estimate the fluctuations that may happen in a short period of time.'

Which means for our asset as example:- Looking at the historical 30 days volatility of 1% in the last 5 years of iShares 1-3 Year Treasury Bond ETF, we see it is relatively lower, thus better in comparison to the benchmark SPY (18.9%)
- Compared with SPY (22.6%) in the period of the last 3 years, the 30 days standard deviation of 1.1% is lower, thus better.

'Downside risk is the financial risk associated with losses. That is, it is the risk of the actual return being below the expected return, or the uncertainty about the magnitude of that difference. 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 (13.8%) in the period of the last 5 years, the downside volatility of 0.6% of iShares 1-3 Year Treasury Bond ETF is smaller, thus better.
- Compared with SPY (16.7%) in the period of the last 3 years, the downside risk of 0.6% is smaller, 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 (0.48) in the period of the last 5 years, the ratio of return and volatility (Sharpe) of -0.78 of iShares 1-3 Year Treasury Bond ETF is lower, thus worse.
- Looking at ratio of return and volatility (Sharpe) in of 0.01 in the period of the last 3 years, we see it is relatively smaller, thus worse in comparison to SPY (0.34).

'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.'

Using this definition on our asset we see for example:- Looking at the downside risk / excess return profile of -1.29 in the last 5 years of iShares 1-3 Year Treasury Bond ETF, we see it is relatively lower, thus worse in comparison to the benchmark SPY (0.65)
- Looking at excess return divided by the downside deviation in of 0.02 in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (0.47).

'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 Downside risk index over 5 years of iShares 1-3 Year Treasury Bond ETF is 0.41 , which is smaller, thus better compared to the benchmark SPY (5.83 ) in the same period.
- Looking at Ulcer Ratio in of 0.27 in the period of the last 3 years, we see it is relatively lower, thus better in comparison to SPY (7.13 ).

'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 -1.1 days of iShares 1-3 Year Treasury Bond ETF is higher, thus better.
- During the last 3 years, the maximum drop from peak to valley is -0.7 days, which is greater, thus better than the value of -33.7 days from the benchmark.

'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:- Compared with the benchmark SPY (139 days) in the period of the last 5 years, the maximum time in days below previous high water mark of 308 days of iShares 1-3 Year Treasury Bond ETF is greater, thus worse.
- During the last 3 years, the maximum days below previous high is 210 days, which is larger, thus worse than the value of 139 days from the benchmark.

'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.'

Applying this definition to our asset in some examples:- The average days under water over 5 years of iShares 1-3 Year Treasury Bond ETF is 85 days, which is higher, thus worse compared to the benchmark SPY (37 days) in the same period.
- Looking at average days below previous high in of 46 days in the period of the last 3 years, we see it is relatively greater, thus worse in comparison to SPY (45 days).
