'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 (78.4%) in the period of the last 5 years, the total return of 131.6% of VanEck Vectors Rare Earth Strategic Metals ETF is higher, thus better.
- Looking at total return in of 141.8% in the period of the last 3 years, we see it is relatively higher, thus better in comparison to SPY (44.1%).

'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 return (CAGR) of 18.3% in the last 5 years of VanEck Vectors Rare Earth Strategic Metals ETF, we see it is relatively higher, thus better in comparison to the benchmark SPY (12.3%)
- Compared with SPY (12.9%) in the period of the last 3 years, the compounded annual growth rate (CAGR) of 34.1% is larger, 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.'

Applying this definition to our asset in some examples:- The volatility over 5 years of VanEck Vectors Rare Earth Strategic Metals ETF is 37%, which is greater, thus worse compared to the benchmark SPY (19.9%) in the same period.
- Looking at 30 days standard deviation in of 42.6% in the period of the last 3 years, we see it is relatively greater, thus worse in comparison to SPY (23.1%).

'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:- The downside risk over 5 years of VanEck Vectors Rare Earth Strategic Metals ETF is 25.6%, which is higher, thus worse compared to the benchmark SPY (14.6%) in the same period.
- During the last 3 years, the downside volatility is 29.2%, which is greater, thus worse than the value of 16.9% from the benchmark.

'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 0.43 in the last 5 years of VanEck Vectors Rare Earth Strategic Metals ETF, we see it is relatively lower, thus worse in comparison to the benchmark SPY (0.49)
- During the last 3 years, the Sharpe Ratio is 0.74, which is larger, thus better than the value of 0.45 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 VanEck Vectors Rare Earth Strategic Metals ETF is 0.62, which is smaller, thus worse compared to the benchmark SPY (0.67) in the same period.
- During the last 3 years, the excess return divided by the downside deviation is 1.08, which is greater, thus better than the value of 0.62 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 (6.16 ) in the period of the last 5 years, the Ulcer Index of 37 of VanEck Vectors Rare Earth Strategic Metals ETF is greater, thus worse.
- Compared with SPY (6.87 ) in the period of the last 3 years, the Downside risk index of 16 is larger, thus worse.

'Maximum drawdown is defined as the peak-to-trough decline of an investment during a specific period. It is usually quoted as a percentage of the peak value. The maximum drawdown can be calculated based on absolute returns, in order to identify strategies that suffer less during market downturns, such as low-volatility strategies. However, the maximum drawdown can also be calculated based on returns relative to a benchmark index, for identifying strategies that show steady outperformance over time.'

Using this definition on our asset we see for example:- The maximum DrawDown over 5 years of VanEck Vectors Rare Earth Strategic Metals ETF is -71.9 days, which is lower, thus worse compared to the benchmark SPY (-33.7 days) in the same period.
- Compared with SPY (-33.7 days) in the period of the last 3 years, the maximum drop from peak to valley of -46.9 days is lower, 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). Many assume Max DD Duration is the length of time between new highs during which the Max DD (magnitude) occurred. But that isn’t always the case. The Max DD duration is the longest time between peaks, period. So it could be the time when the program also had its biggest peak to valley loss (and usually is, because the program needs a long time to recover from the largest loss), but it doesn’t have to be'

Which means for our asset as example:- Looking at the maximum days under water of 776 days in the last 5 years of VanEck Vectors Rare Earth Strategic Metals ETF, we see it is relatively higher, thus worse in comparison to the benchmark SPY (139 days)
- Compared with SPY (119 days) in the period of the last 3 years, the maximum time in days below previous high water mark of 340 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 time in days below previous high water mark of 263 days in the last 5 years of VanEck Vectors Rare Earth Strategic Metals ETF, we see it is relatively larger, thus worse in comparison to the benchmark SPY (35 days)
- During the last 3 years, the average days below previous high is 97 days, which is larger, thus worse than the value of 27 days from the benchmark.
