'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.'

Applying this definition to our asset in some examples:- The total return, or performance over 5 years of iShares Currency Hedged MSCI United Kingdom ETF is %, which is lower, thus worse compared to the benchmark SPY (66.6%) in the same period.
- Looking at total return in of -3.6% in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (36.1%).

'Compound annual growth rate (CAGR) is a business and investing specific term for the geometric progression ratio that provides a constant rate of return over the time period. CAGR is not an accounting term, but it is often used to describe some element of the business, for example revenue, units delivered, registered users, etc. CAGR dampens the effect of volatility of periodic returns that can render arithmetic means irrelevant. It is particularly useful to compare growth rates from various data sets of common domain such as revenue growth of companies in the same industry.'

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 United Kingdom ETF, we see it is relatively lower, thus worse in comparison to the benchmark SPY (10.8%)
- Looking at annual return (CAGR) in of -1.3% in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (10.8%).

'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.'

Using this definition on our asset we see for example:- Looking at the 30 days standard deviation of % in the last 5 years of iShares Currency Hedged MSCI United Kingdom ETF, we see it is relatively lower, thus better in comparison to the benchmark SPY (19%)
- Looking at historical 30 days volatility in of 20.3% in the period of the last 3 years, we see it is relatively smaller, thus better in comparison to SPY (22%).

'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 % in the last 5 years of iShares Currency Hedged MSCI United Kingdom ETF, we see it is relatively lower, thus better in comparison to the benchmark SPY (13.9%)
- Looking at downside deviation in of 15.6% in the period of the last 3 years, we see it is relatively lower, thus better in comparison to SPY (16.2%).

'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:- The Sharpe Ratio over 5 years of iShares Currency Hedged MSCI United Kingdom ETF is , which is smaller, thus worse compared to the benchmark SPY (0.43) in the same period.
- Looking at Sharpe Ratio in of -0.18 in the period of the last 3 years, we see it is relatively smaller, thus worse in comparison to SPY (0.38).

'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:- Compared with the benchmark SPY (0.59) in the period of the last 5 years, the downside risk / excess return profile of of iShares Currency Hedged MSCI United Kingdom ETF is smaller, thus worse.
- During the last 3 years, the excess return divided by the downside deviation is -0.24, which is lower, thus worse than the value of 0.52 from the benchmark.

'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:- The Downside risk index over 5 years of iShares Currency Hedged MSCI United Kingdom ETF is , which is lower, thus better compared to the benchmark SPY (5.9 ) in the same period.
- During the last 3 years, the Downside risk index is 8.8 , which is greater, thus worse than the value of 6.98 from the benchmark.

'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 DrawDown of days in the last 5 years of iShares Currency Hedged MSCI United Kingdom ETF, we see it is relatively greater, 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 -33.1 days is larger, thus better.

'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 Currency Hedged MSCI United Kingdom ETF is days, which is smaller, 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 222 days is higher, 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 United Kingdom ETF, we see it is relatively smaller, thus better in comparison to the benchmark SPY (44 days)
- Compared with SPY (41 days) in the period of the last 3 years, the average time in days below previous high water mark of 60 days is higher, thus worse.
