'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 (63%) in the period of the last 5 years, the total return of 28.3% of VanEck Vectors Rare Earth Strategic Metals ETF is lower, thus worse.
- Compared with SPY (33.5%) in the period of the last 3 years, the total return, or performance of 184.8% is higher, thus better.

'The compound annual growth rate (CAGR) is a useful measure of growth over multiple time periods. It can be thought of as the growth rate that gets you from the initial investment value to the ending investment value if you assume that the investment has been compounding over the time period.'

Using this definition on our asset we see for example:- Looking at the annual return (CAGR) of 5.1% 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 (10.3%)
- During the last 3 years, the annual performance (CAGR) is 41.7%, which is larger, thus better than the value of 10.1% from the benchmark.

'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:- Looking at the historical 30 days volatility of 39.5% 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 (21.6%)
- Looking at volatility in of 46% in the period of the last 3 years, we see it is relatively higher, thus worse in comparison to SPY (25.1%).

'The downside volatility is similar to the volatility, or standard deviation, but only takes losing/negative periods into account.'

Which means for our asset as example:- The downside volatility over 5 years of VanEck Vectors Rare Earth Strategic Metals ETF is 27.4%, which is higher, thus worse compared to the benchmark SPY (15.6%) in the same period.
- Compared with SPY (18.1%) in the period of the last 3 years, the downside deviation of 31.3% is larger, thus worse.

'The Sharpe ratio is the measure of risk-adjusted return of a financial portfolio. Sharpe ratio is a measure of excess portfolio return over the risk-free rate relative to its standard deviation. Normally, the 90-day Treasury bill rate is taken as the proxy for risk-free rate. A portfolio with a higher Sharpe ratio is considered superior relative to its peers. The measure was named after William F Sharpe, a Nobel laureate and professor of finance, emeritus at Stanford University.'

Using this definition on our asset we see for example:- Looking at the Sharpe Ratio of 0.07 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 (0.36)
- Compared with SPY (0.3) in the period of the last 3 years, the Sharpe Ratio of 0.85 is higher, thus better.

'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.'

Applying this definition to our asset in some examples:- Looking at the downside risk / excess return profile of 0.1 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 (0.5)
- Compared with SPY (0.42) in the period of the last 3 years, the ratio of annual return and downside deviation of 1.25 is higher, thus better.

'Ulcer Index is a method for measuring investment risk that addresses the real concerns of investors, unlike the widely used standard deviation of return. UI is a measure of the depth and duration of drawdowns in prices from earlier highs. Using Ulcer Index instead of standard deviation can lead to very different conclusions about investment risk and risk-adjusted return, especially when evaluating strategies that seek to avoid major declines in portfolio value (market timing, dynamic asset allocation, hedge funds, etc.). The Ulcer Index was originally developed in 1987. Since then, it has been widely recognized and adopted by the investment community. According to Nelson Freeburg, editor of Formula Research, Ulcer Index is “perhaps the most fully realized statistical portrait of risk there is.'

Which means for our asset as example:- The Ulcer Index over 5 years of VanEck Vectors Rare Earth Strategic Metals ETF is 37 , which is greater, thus worse compared to the benchmark SPY (8.88 ) in the same period.
- Compared with SPY (11 ) in the period of the last 3 years, the Downside risk index of 19 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 -70.4 days, which is lower, thus worse compared to the benchmark SPY (-33.7 days) in the same period.
- Looking at maximum DrawDown in of -41.2 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 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.'

Using this definition on our asset we see for example:- Looking at the maximum days below previous high of 730 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 (273 days)
- Compared with SPY (273 days) in the period of the last 3 years, the maximum days under water of 210 days is smaller, thus better.

'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:- Looking at the average time in days below previous high water mark of 243 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 (57 days)
- During the last 3 years, the average time in days below previous high water mark is 57 days, which is lower, thus better than the value of 73 days from the benchmark.
