'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:- Compared with the benchmark SPY (62.7%) in the period of the last 5 years, the total return, or performance of -22.9% of WisdomTree Middle East Dividend Fund is lower, thus worse.
- Compared with SPY (34.7%) in the period of the last 3 years, the total return, or performance of -6.7% is lower, thus worse.

'The compound annual growth rate isn't a true return rate, but rather a representational figure. It is essentially a number that describes the rate at which an investment would have grown if it had grown the same rate every year and the profits were reinvested at the end of each year. In reality, this sort of performance is unlikely. However, CAGR can be used to smooth returns so that they may be more easily understood when compared to alternative investments.'

Using this definition on our asset we see for example:- Looking at the annual performance (CAGR) of -5.1% in the last 5 years of WisdomTree Middle East Dividend Fund, we see it is relatively lower, thus worse in comparison to the benchmark SPY (10.2%)
- During the last 3 years, the annual performance (CAGR) is -2.3%, which is lower, thus worse than the value of 10.5% 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.'

Which means for our asset as example:- The volatility over 5 years of WisdomTree Middle East Dividend Fund is 21.3%, which is larger, thus worse compared to the benchmark SPY (20.9%) in the same period.
- Looking at 30 days standard deviation in of 23.8% in the period of the last 3 years, we see it is relatively lower, thus better in comparison to SPY (24.1%).

'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.'

Using this definition on our asset we see for example:- Looking at the downside risk of 16.5% in the last 5 years of WisdomTree Middle East Dividend Fund, we see it is relatively greater, thus worse in comparison to the benchmark SPY (15.3%)
- Compared with SPY (17.6%) in the period of the last 3 years, the downside risk of 18.7% is higher, thus worse.

'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.'

Which means for our asset as example:- Looking at the risk / return profile (Sharpe) of -0.36 in the last 5 years of WisdomTree Middle East Dividend Fund, we see it is relatively lower, thus worse in comparison to the benchmark SPY (0.37)
- During the last 3 years, the risk / return profile (Sharpe) is -0.2, which is smaller, thus worse than the value of 0.33 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:- Compared with the benchmark SPY (0.51) in the period of the last 5 years, the ratio of annual return and downside deviation of -0.46 of WisdomTree Middle East Dividend Fund is smaller, thus worse.
- During the last 3 years, the ratio of annual return and downside deviation is -0.26, which is lower, thus worse than the value of 0.45 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.'

Applying this definition to our asset in some examples:- Compared with the benchmark SPY (7.71 ) in the period of the last 5 years, the Downside risk index of 16 of WisdomTree Middle East Dividend Fund is larger, thus worse.
- During the last 3 years, the Ulcer Index is 9.55 , which is greater, thus worse than the value of 9.08 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.'

Applying this definition to our asset in some examples:- Compared with the benchmark SPY (-33.7 days) in the period of the last 5 years, the maximum DrawDown of -40.3 days of WisdomTree Middle East Dividend Fund is lower, thus worse.
- During the last 3 years, the maximum drop from peak to valley is -40.3 days, which is lower, thus worse than the value of -33.7 days from the benchmark.

'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.'

Which means for our asset as example:- Compared with the benchmark SPY (189 days) in the period of the last 5 years, the maximum days below previous high of 982 days of WisdomTree Middle East Dividend Fund is greater, thus worse.
- During the last 3 years, the maximum days below previous high is 269 days, which is greater, thus worse than the value of 189 days from the benchmark.

'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.'

Which means for our asset as example:- Looking at the average days below previous high of 413 days in the last 5 years of WisdomTree Middle East Dividend Fund, we see it is relatively higher, thus worse in comparison to the benchmark SPY (46 days)
- Compared with SPY (45 days) in the period of the last 3 years, the average time in days below previous high water mark of 70 days is larger, thus worse.
