'The total return on a portfolio of investments takes into account not only the capital appreciation on the portfolio, but also the income received on the portfolio. The income typically consists of interest, dividends, and securities lending fees. This contrasts with the price return, which takes into account only the capital gain on an investment.'

Applying this definition to our asset in some examples:- Compared with the benchmark SPY (78.4%) in the period of the last 5 years, the total return, or increase in value of 78.3% of First Trust Indxx Global Natural Resources is smaller, thus worse.
- During the last 3 years, the total return, or performance is 51.6%, which is larger, thus better than the value of 44.1% from the benchmark.

'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.'

Applying this definition to our asset in some examples:- Looking at the compounded annual growth rate (CAGR) of 12.8% in the last 5 years of First Trust Indxx Global Natural Resources, we see it is relatively higher, thus better in comparison to the benchmark SPY (12.3%)
- Looking at compounded annual growth rate (CAGR) in of 15% in the period of the last 3 years, we see it is relatively larger, thus better 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:- Compared with the benchmark SPY (19.9%) in the period of the last 5 years, the historical 30 days volatility of 24.3% of First Trust Indxx Global Natural Resources is higher, thus worse.
- Compared with SPY (23.1%) in the period of the last 3 years, the historical 30 days volatility of 28.9% is greater, thus worse.

'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.'

Applying this definition to our asset in some examples:- Compared with the benchmark SPY (14.6%) in the period of the last 5 years, the downside volatility of 17.7% of First Trust Indxx Global Natural Resources is higher, thus worse.
- Compared with SPY (16.9%) in the period of the last 3 years, the downside deviation of 21.1% is higher, thus worse.

'The Sharpe ratio was developed by Nobel laureate William F. Sharpe, and is used to help investors understand the return of an investment compared to its risk. The ratio is the average return earned in excess of the risk-free rate per unit of volatility or total risk. Subtracting the risk-free rate from the mean return allows an investor to better isolate the profits associated with risk-taking activities. One intuition of this calculation is that a portfolio engaging in 'zero risk' investments, such as the purchase of U.S. Treasury bills (for which the expected return is the risk-free rate), has a Sharpe ratio of exactly zero. Generally, the greater the value of the Sharpe ratio, the more attractive the risk-adjusted return.'

Using this definition on our asset we see for example:- Looking at the risk / return profile (Sharpe) of 0.42 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 (0.49)
- During the last 3 years, the ratio of return and volatility (Sharpe) is 0.43, which is lower, thus worse than the value of 0.45 from the benchmark.

'The Sortino ratio improves upon the Sharpe ratio by isolating downside volatility from total volatility by dividing excess return by the downside deviation. The Sortino ratio is a variation of the Sharpe ratio that differentiates harmful volatility from total overall volatility by using the asset's standard deviation of negative asset returns, called downside deviation. The Sortino ratio takes the asset's return and subtracts the risk-free rate, and then divides that amount by the asset's downside deviation. The ratio was named after Frank A. Sortino.'

Which means for our asset as example:- The downside risk / excess return profile over 5 years of First Trust Indxx Global Natural Resources is 0.58, 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 excess return divided by the downside deviation of 0.59 is lower, thus worse.

'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:- 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 (6.16 ) in the same period.
- Looking at Downside risk index in of 14 in the period of the last 3 years, we see it is relatively higher, thus worse in comparison to SPY (6.87 ).

'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 -43.9 days of First Trust Indxx Global Natural Resources is lower, thus worse.
- Looking at maximum DrawDown in of -43.9 days in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (-33.7 days).

'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.'

Which means for our asset as example:- The maximum days below previous high over 5 years of First Trust Indxx Global Natural Resources is 238 days, which is higher, thus worse compared to the benchmark SPY (139 days) in the same period.
- Compared with SPY (119 days) in the period of the last 3 years, the maximum days below previous high of 238 days is larger, 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.'

Which means for our asset as example:- Looking at the average days under water of 74 days 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 (35 days)
- Looking at average days under water in of 74 days in the period of the last 3 years, we see it is relatively larger, thus worse in comparison to SPY (27 days).
