'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:- Compared with the benchmark SPY (116.9%) in the period of the last 5 years, the total return, or increase in value of 58.8% of First Trust Indxx Global Natural Resources is lower, thus worse.
- Compared with SPY (63.4%) in the period of the last 3 years, the total return of 25.9% 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 compounded annual growth rate (CAGR) of 10.6% in the last 5 years of First Trust Indxx Global Natural Resources, we see it is relatively lower, thus worse in comparison to the benchmark SPY (16.8%)
- During the last 3 years, the compounded annual growth rate (CAGR) is 8.7%, which is smaller, thus worse than the value of 17.8% 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.'

Using this definition on our asset we see for example:- Looking at the historical 30 days volatility of 24.3% in the last 5 years of First Trust Indxx Global Natural Resources, we see it is relatively greater, thus worse in comparison to the benchmark SPY (18.7%)
- Looking at volatility in of 28% in the period of the last 3 years, we see it is relatively higher, thus worse in comparison to SPY (22.5%).

'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:- Compared with the benchmark SPY (13.6%) in the period of the last 5 years, the downside deviation of 17.7% of First Trust Indxx Global Natural Resources is larger, thus worse.
- Looking at downside deviation in of 20.5% in the period of the last 3 years, we see it is relatively greater, thus worse in comparison to SPY (16.3%).

'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:- Looking at the ratio of return and volatility (Sharpe) of 0.33 in the last 5 years of First Trust Indxx Global Natural Resources, we see it is relatively lower, thus worse in comparison to the benchmark SPY (0.76)
- Looking at Sharpe Ratio in of 0.22 in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (0.68).

'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:- The ratio of annual return and downside deviation over 5 years of First Trust Indxx Global Natural Resources is 0.46, which is lower, thus worse compared to the benchmark SPY (1.05) in the same period.
- Looking at excess return divided by the downside deviation in of 0.31 in the period of the last 3 years, we see it is relatively smaller, thus worse in comparison to SPY (0.94).

'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 First Trust Indxx Global Natural Resources is 11 , which is greater, thus worse compared to the benchmark SPY (5.58 ) in the same period.
- Looking at Downside risk index in of 13 in the period of the last 3 years, we see it is relatively higher, thus worse in comparison to SPY (6.83 ).

'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.'

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 -43.9 days of First Trust Indxx Global Natural Resources is lower, thus worse.
- Compared with SPY (-33.7 days) in the period of the last 3 years, the maximum reduction from previous high of -43.9 days is smaller, thus worse.

'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 (139 days) in the period of the last 5 years, the maximum days under water of 223 days of First Trust Indxx Global Natural Resources is larger, thus worse.
- Compared with SPY (139 days) in the period of the last 3 years, the maximum days under water of 223 days is greater, 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 below previous high of 68 days in the last 5 years of First Trust Indxx Global Natural Resources, we see it is relatively higher, thus worse in comparison to the benchmark SPY (33 days)
- Looking at average days under water in of 87 days in the period of the last 3 years, we see it is relatively larger, thus worse in comparison to SPY (35 days).
