'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.'

Which means for our asset as example:- The total return, or increase in value over 5 years of VanEck Vectors Natural Resources ETF is 58.9%, which is smaller, thus worse compared to the benchmark SPY (80%) in the same period.
- Compared with SPY (31.8%) in the period of the last 3 years, the total return, or increase in value of 41.3% is greater, thus better.

'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:- Compared with the benchmark SPY (12.5%) in the period of the last 5 years, the compounded annual growth rate (CAGR) of 9.7% of VanEck Vectors Natural Resources ETF is lower, thus worse.
- Compared with SPY (9.7%) in the period of the last 3 years, the compounded annual growth rate (CAGR) of 12.2% is greater, thus better.

'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.'

Using this definition on our asset we see for example:- Compared with the benchmark SPY (21.3%) in the period of the last 5 years, the historical 30 days volatility of 23.7% of VanEck Vectors Natural Resources ETF is higher, thus worse.
- Compared with SPY (17.6%) in the period of the last 3 years, the 30 days standard deviation of 19.9% is larger, 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.'

Using this definition on our asset we see for example:- The downside risk over 5 years of VanEck Vectors Natural Resources ETF is 17.4%, which is greater, thus worse compared to the benchmark SPY (15.3%) in the same period.
- During the last 3 years, the downside volatility is 14.1%, which is greater, thus worse than the value of 12.3% from the benchmark.

'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 Sharpe Ratio of 0.31 in the last 5 years of VanEck Vectors Natural Resources ETF, we see it is relatively lower, thus worse in comparison to the benchmark SPY (0.47)
- During the last 3 years, the ratio of return and volatility (Sharpe) is 0.49, which is higher, thus better than the value of 0.41 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.'

Applying this definition to our asset in some examples:- The downside risk / excess return profile over 5 years of VanEck Vectors Natural Resources ETF is 0.41, which is lower, thus worse compared to the benchmark SPY (0.66) in the same period.
- Looking at downside risk / excess return profile in of 0.69 in the period of the last 3 years, we see it is relatively higher, thus better in comparison to SPY (0.58).

'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.'

Which means for our asset as example:- Looking at the Ulcer Index of 11 in the last 5 years of VanEck Vectors Natural Resources ETF, we see it is relatively higher, thus worse in comparison to the benchmark SPY (9.43 )
- Compared with SPY (10 ) in the period of the last 3 years, the Ulcer Index of 10 is larger, thus worse.

'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:- The maximum reduction from previous high over 5 years of VanEck Vectors Natural Resources ETF is -43.9 days, which is lower, thus worse compared to the benchmark SPY (-33.7 days) in the same period.
- During the last 3 years, the maximum drop from peak to valley is -25.7 days, which is smaller, thus worse than the value of -24.5 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.'

Applying this definition to our asset in some examples:- Compared with the benchmark SPY (480 days) in the period of the last 5 years, the maximum time in days below previous high water mark of 406 days of VanEck Vectors Natural Resources ETF is smaller, thus better.
- During the last 3 years, the maximum days below previous high is 406 days, which is smaller, thus better than the value of 480 days from the benchmark.

'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.'

Which means for our asset as example:- Compared with the benchmark SPY (119 days) in the period of the last 5 years, the average days below previous high of 112 days of VanEck Vectors Natural Resources ETF is lower, thus better.
- Compared with SPY (174 days) in the period of the last 3 years, the average days below previous high of 139 days is lower, thus better.
