'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:- The total return, or performance over 5 years of iShares Currency Hedged MSCI Canada ETF is %, which is lower, thus worse compared to the benchmark SPY (65.6%) in the same period.
- Compared with SPY (48.8%) in the period of the last 3 years, the total return, or increase in value of 26.5% 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.'

Applying this definition to our asset in some examples:- Looking at the annual performance (CAGR) of % in the last 5 years of iShares Currency Hedged MSCI Canada ETF, we see it is relatively smaller, thus worse in comparison to the benchmark SPY (10.6%)
- During the last 3 years, the compounded annual growth rate (CAGR) is 10.9%, which is lower, thus worse than the value of 14.2% from the benchmark.

'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 (13.6%) in the period of the last 5 years, the historical 30 days volatility of % of iShares Currency Hedged MSCI Canada ETF is smaller, thus better.
- Looking at 30 days standard deviation in of 11.1% in the period of the last 3 years, we see it is relatively lower, thus better in comparison to SPY (12.8%).

'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.'

Applying this definition to our asset in some examples:- Looking at the downside risk of % in the last 5 years of iShares Currency Hedged MSCI Canada ETF, we see it is relatively smaller, thus better in comparison to the benchmark SPY (15%)
- Compared with SPY (14.6%) in the period of the last 3 years, the downside volatility of 12% 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.'

Using this definition on our asset we see for example:- Compared with the benchmark SPY (0.6) in the period of the last 5 years, the risk / return profile (Sharpe) of of iShares Currency Hedged MSCI Canada ETF is lower, thus worse.
- Compared with SPY (0.91) in the period of the last 3 years, the ratio of return and volatility (Sharpe) of 0.76 is smaller, thus worse.

'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.'

Which means for our asset as example:- Looking at the ratio of annual return and downside deviation of in the last 5 years of iShares Currency Hedged MSCI Canada ETF, we see it is relatively lower, thus worse in comparison to the benchmark SPY (0.54)
- Looking at downside risk / excess return profile in of 0.7 in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (0.8).

'Ulcer Index is a method for measuring investment risk that addresses the real concerns of investors, unlike the widely used standard deviation of return. UI is a measure of the depth and duration of drawdowns in prices from earlier highs. Using Ulcer Index instead of standard deviation can lead to very different conclusions about investment risk and risk-adjusted return, especially when evaluating strategies that seek to avoid major declines in portfolio value (market timing, dynamic asset allocation, hedge funds, etc.). The Ulcer Index was originally developed in 1987. Since then, it has been widely recognized and adopted by the investment community. According to Nelson Freeburg, editor of Formula Research, Ulcer Index is “perhaps the most fully realized statistical portrait of risk there is.'

Applying this definition to our asset in some examples:- Compared with the benchmark SPY (4.03 ) in the period of the last 5 years, the Ulcer Ratio of of iShares Currency Hedged MSCI Canada ETF is smaller, thus better.
- Looking at Ulcer Ratio in of 4.28 in the period of the last 3 years, we see it is relatively larger, thus worse in comparison to SPY (4.1 ).

'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.'

Using this definition on our asset we see for example:- Looking at the maximum drop from peak to valley of days in the last 5 years of iShares Currency Hedged MSCI Canada ETF, we see it is relatively higher, thus better in comparison to the benchmark SPY (-19.3 days)
- Compared with SPY (-19.3 days) in the period of the last 3 years, the maximum DrawDown of -16.7 days is greater, 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'

Applying this definition to our asset in some examples:- The maximum days under water over 5 years of iShares Currency Hedged MSCI Canada ETF is days, which is lower, thus better compared to the benchmark SPY (187 days) in the same period.
- Compared with SPY (139 days) in the period of the last 3 years, the maximum days under water of 149 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:- Looking at the average days under water of days in the last 5 years of iShares Currency Hedged MSCI Canada ETF, we see it is relatively lower, thus better in comparison to the benchmark SPY (41 days)
- During the last 3 years, the average days below previous high is 48 days, which is larger, thus worse than the value of 35 days from the benchmark.
