'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 investment’s overall performance.'

Applying this definition to our asset in some examples:- Looking at the total return, or increase in value of % in the last 5 years of WisdomTree United Kingdom Hedged Equity Fund, we see it is relatively smaller, thus worse in comparison to the benchmark SPY (106.8%)
- Compared with SPY (71.9%) in the period of the last 3 years, the total return of 17.1% is smaller, 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.'

Applying this definition to our asset in some examples:- Compared with the benchmark SPY (15.7%) in the period of the last 5 years, the annual return (CAGR) of % of WisdomTree United Kingdom Hedged Equity Fund is lower, thus worse.
- Looking at compounded annual growth rate (CAGR) in of 5.4% in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (19.8%).

'In finance, volatility (symbol σ) is the degree of variation of a trading price series over time as measured by the standard deviation of logarithmic returns. Historic volatility measures a time series of past market prices. Implied volatility looks forward in time, being derived from the market price of a market-traded derivative (in particular, an option). Commonly, the higher the volatility, the riskier the security.'

Applying this definition to our asset in some examples:- Looking at the 30 days standard deviation of % in the last 5 years of WisdomTree United Kingdom Hedged Equity Fund, we see it is relatively lower, thus better in comparison to the benchmark SPY (18.9%)
- Looking at volatility in of 15.7% in the period of the last 3 years, we see it is relatively lower, thus better in comparison to SPY (21.9%).

'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:- The downside risk over 5 years of WisdomTree United Kingdom Hedged Equity Fund is %, which is lower, thus better compared to the benchmark SPY (13.8%) in the same period.
- Looking at downside volatility in of 11.2% in the period of the last 3 years, we see it is relatively lower, thus better in comparison to SPY (15.9%).

'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:- Looking at the Sharpe Ratio of in the last 5 years of WisdomTree United Kingdom Hedged Equity Fund, we see it is relatively smaller, thus worse in comparison to the benchmark SPY (0.69)
- During the last 3 years, the risk / return profile (Sharpe) is 0.18, which is lower, thus worse than the value of 0.79 from the benchmark.

'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.'

Using this definition on our asset we see for example:- The ratio of annual return and downside deviation over 5 years of WisdomTree United Kingdom Hedged Equity Fund is , which is smaller, thus worse compared to the benchmark SPY (0.95) in the same period.
- Looking at excess return divided by the downside deviation in of 0.26 in the period of the last 3 years, we see it is relatively smaller, thus worse in comparison to SPY (1.09).

'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.'

Applying this definition to our asset in some examples:- Compared with the benchmark SPY (5.61 ) in the period of the last 5 years, the Downside risk index of of WisdomTree United Kingdom Hedged Equity Fund is lower, thus better.
- During the last 3 years, the Downside risk index is 6.93 , which is greater, thus worse than the value of 6.08 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:- Compared with the benchmark SPY (-33.7 days) in the period of the last 5 years, the maximum reduction from previous high of days of WisdomTree United Kingdom Hedged Equity Fund is greater, thus better.
- Compared with SPY (-33.7 days) in the period of the last 3 years, the maximum reduction from previous high of -19.5 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.'

Applying this definition to our asset in some examples:- Looking at the maximum days under water of days in the last 5 years of WisdomTree United Kingdom Hedged Equity Fund, we see it is relatively lower, thus better in comparison to the benchmark SPY (139 days)
- Looking at maximum days below previous high in of 306 days in the period of the last 3 years, we see it is relatively higher, thus worse in comparison to SPY (119 days).

'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 time in days below previous high water mark over 5 years of WisdomTree United Kingdom Hedged Equity Fund is days, which is lower, thus better compared to the benchmark SPY (32 days) in the same period.
- Looking at average time in days below previous high water mark in of 81 days in the period of the last 3 years, we see it is relatively greater, thus worse in comparison to SPY (22 days).
