'Total return is the amount of value an investor earns from a security over a specific period, typically one year, when all distributions are reinvested. Total return is expressed as a percentage of the amount invested. For example, a total return of 20% means the security increased by 20% of its original value due to a price increase, distribution of dividends (if a stock), coupons (if a bond) or capital gains (if a fund). Total return is a strong measure of an investmentâ€™s overall performance.'

Which means for our asset as example:- The total return, or performance over 5 years of XTrackers MSCI South Korea Hedged Equity ETF is 19.9%, which is smaller, thus worse compared to the benchmark SPY (78.4%) in the same period.
- Looking at total return in of 21.4% in the period of the last 3 years, we see it is relatively smaller, thus worse in comparison to SPY (44.1%).

'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:- The annual performance (CAGR) over 5 years of XTrackers MSCI South Korea Hedged Equity ETF is 3.7%, which is lower, thus worse compared to the benchmark SPY (12.3%) in the same period.
- Looking at annual performance (CAGR) in of 6.7% in the period of the last 3 years, we see it is relatively smaller, thus worse in comparison to SPY (12.9%).

'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:- Looking at the volatility of 14.3% in the last 5 years of XTrackers MSCI South Korea Hedged Equity ETF, we see it is relatively lower, thus better in comparison to the benchmark SPY (19.9%)
- Compared with SPY (23.1%) in the period of the last 3 years, the 30 days standard deviation of 13.7% is lower, thus better.

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

Using this definition on our asset we see for example:- The downside deviation over 5 years of XTrackers MSCI South Korea Hedged Equity ETF is 10.3%, which is smaller, thus better compared to the benchmark SPY (14.6%) in the same period.
- Looking at downside risk in of 9.9% in the period of the last 3 years, we see it is relatively lower, thus better in comparison to SPY (16.9%).

'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.'

Applying this definition to our asset in some examples:- The risk / return profile (Sharpe) over 5 years of XTrackers MSCI South Korea Hedged Equity ETF is 0.08, which is smaller, thus worse compared to the benchmark SPY (0.49) in the same period.
- Looking at risk / return profile (Sharpe) in of 0.31 in the period of the last 3 years, we see it is relatively smaller, thus worse in comparison to SPY (0.45).

'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.'

Applying this definition to our asset in some examples:- The downside risk / excess return profile over 5 years of XTrackers MSCI South Korea Hedged Equity ETF is 0.12, which is smaller, thus worse compared to the benchmark SPY (0.67) in the same period.
- Compared with SPY (0.62) in the period of the last 3 years, the downside risk / excess return profile of 0.42 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:- The Downside risk index over 5 years of XTrackers MSCI South Korea Hedged Equity ETF is 11 , which is higher, thus worse compared to the benchmark SPY (6.16 ) in the same period.
- Compared with SPY (6.87 ) in the period of the last 3 years, the Downside risk index of 11 is larger, thus worse.

'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:- Compared with the benchmark SPY (-33.7 days) in the period of the last 5 years, the maximum reduction from previous high of -23.6 days of XTrackers MSCI South Korea Hedged Equity ETF is higher, thus better.
- Compared with SPY (-33.7 days) in the period of the last 3 years, the maximum DrawDown of -23.6 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) in days.'

Using this definition on our asset we see for example:- Looking at the maximum days under water of 451 days in the last 5 years of XTrackers MSCI South Korea Hedged Equity ETF, we see it is relatively higher, thus worse in comparison to the benchmark SPY (139 days)
- Compared with SPY (119 days) in the period of the last 3 years, the maximum days under water of 451 days is greater, thus worse.

'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:- Compared with the benchmark SPY (35 days) in the period of the last 5 years, the average days below previous high of 173 days of XTrackers MSCI South Korea Hedged Equity ETF is larger, thus worse.
- During the last 3 years, the average days below previous high is 155 days, which is greater, thus worse than the value of 27 days from the benchmark.
