'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.'

Using this definition on our asset we see for example:- The total return, or performance over 5 years of iShares Currency Hedged MSCI Australia ETF is 32.4%, which is lower, thus worse compared to the benchmark SPY (81.9%) in the same period.
- Compared with SPY (46.1%) in the period of the last 3 years, the total return, or performance of 19.7% is lower, thus worse.

'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.'

Using this definition on our asset we see for example:- Looking at the annual return (CAGR) of 11.3% in the last 5 years of iShares Currency Hedged MSCI Australia ETF, we see it is relatively smaller, thus worse in comparison to the benchmark SPY (12.7%)
- Compared with SPY (13.5%) in the period of the last 3 years, the annual return (CAGR) of 9% is lower, thus worse.

'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:- Compared with the benchmark SPY (19.8%) in the period of the last 5 years, the historical 30 days volatility of 28.6% of iShares Currency Hedged MSCI Australia ETF is greater, thus worse.
- Looking at volatility in of 27.2% in the period of the last 3 years, we see it is relatively larger, thus worse in comparison to SPY (23%).

'The downside volatility is similar to the volatility, or standard deviation, but only takes losing/negative periods into account.'

Applying this definition to our asset in some examples:- Looking at the downside risk of 20.7% in the last 5 years of iShares Currency Hedged MSCI Australia ETF, we see it is relatively larger, thus worse in comparison to the benchmark SPY (14.5%)
- Looking at downside deviation in of 19.9% in the period of the last 3 years, we see it is relatively larger, thus worse in comparison to SPY (16.8%).

'The Sharpe ratio is the measure of risk-adjusted return of a financial portfolio. Sharpe ratio is a measure of excess portfolio return over the risk-free rate relative to its standard deviation. Normally, the 90-day Treasury bill rate is taken as the proxy for risk-free rate. A portfolio with a higher Sharpe ratio is considered superior relative to its peers. The measure was named after William F Sharpe, a Nobel laureate and professor of finance, emeritus at Stanford University.'

Using this definition on our asset we see for example:- Compared with the benchmark SPY (0.52) in the period of the last 5 years, the risk / return profile (Sharpe) of 0.31 of iShares Currency Hedged MSCI Australia ETF is smaller, thus worse.
- During the last 3 years, the ratio of return and volatility (Sharpe) is 0.24, which is lower, thus worse than the value of 0.48 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.'

Using this definition on our asset we see for example:- Compared with the benchmark SPY (0.7) in the period of the last 5 years, the ratio of annual return and downside deviation of 0.42 of iShares Currency Hedged MSCI Australia ETF is smaller, thus worse.
- Compared with SPY (0.65) in the period of the last 3 years, the excess return divided by the downside deviation of 0.33 is lower, thus worse.

'The ulcer index is a stock market risk measure or technical analysis indicator devised by Peter Martin in 1987, and published by him and Byron McCann in their 1989 book The Investors Guide to Fidelity Funds. It's designed as a measure of volatility, but only volatility in the downward direction, i.e. the amount of drawdown or retracement occurring over a period. Other volatility measures like standard deviation treat up and down movement equally, but a trader doesn't mind upward movement, it's the downside that causes stress and stomach ulcers that the index's name suggests.'

Using this definition on our asset we see for example:- Compared with the benchmark SPY (6.08 ) in the period of the last 5 years, the Ulcer Index of 9.4 of iShares Currency Hedged MSCI Australia ETF is higher, thus worse.
- Compared with SPY (6.77 ) in the period of the last 3 years, the Downside risk index of 10 is higher, thus worse.

'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:- Looking at the maximum DrawDown of -32.5 days in the last 5 years of iShares Currency Hedged MSCI Australia ETF, we see it is relatively higher, thus better in comparison to the benchmark SPY (-33.7 days)
- During the last 3 years, the maximum reduction from previous high is -32.5 days, which is higher, thus better than the value of -33.7 days from the benchmark.

'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.'

Applying this definition to our asset in some examples:- Looking at the maximum days under water of 127 days in the last 5 years of iShares Currency Hedged MSCI Australia ETF, we see it is relatively smaller, thus better in comparison to the benchmark SPY (139 days)
- Looking at maximum days below previous high in of 127 days in the period of the last 3 years, we see it is relatively larger, thus worse in comparison to SPY (119 days).

'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.'

Using this definition on our asset we see for example:- Looking at the average days under water of 28 days in the last 5 years of iShares Currency Hedged MSCI Australia ETF, we see it is relatively smaller, thus better in comparison to the benchmark SPY (35 days)
- During the last 3 years, the average time in days below previous high water mark is 31 days, which is higher, thus worse than the value of 27 days from the benchmark.
