'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.'

Using this definition on our asset we see for example:- Compared with the benchmark SPY (68.1%) in the period of the last 5 years, the total return of 24.3% of VanEck Vectors Uranium & Nuclear Energy ETF is lower, thus worse.
- During the last 3 years, the total return, or increase in value is 24.1%, which is smaller, thus worse than the value of 47.1% 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:- The annual performance (CAGR) over 5 years of VanEck Vectors Uranium & Nuclear Energy ETF is 4.4%, which is smaller, thus worse compared to the benchmark SPY (11%) in the same period.
- During the last 3 years, the annual return (CAGR) is 7.5%, which is lower, thus worse than the value of 13.8% from the benchmark.

'Volatility is a rate at which the price of a security increases or decreases for a given set of returns. Volatility is measured by calculating the standard deviation of the annualized returns over a given period of time. It shows the range to which the price of a security may increase or decrease. Volatility measures the risk of a security. It is used in option pricing formula to gauge the fluctuations in the returns of the underlying assets. Volatility indicates the pricing behavior of the security and helps estimate the fluctuations that may happen in a short period of time.'

Applying this definition to our asset in some examples:- The 30 days standard deviation over 5 years of VanEck Vectors Uranium & Nuclear Energy ETF is 12.8%, which is smaller, thus better compared to the benchmark SPY (13.2%) in the same period.
- During the last 3 years, the historical 30 days volatility is 11.6%, which is lower, thus better than the value of 12.4% from the benchmark.

'Downside risk is the financial risk associated with losses. That is, it is the risk of the actual return being below the expected return, or the uncertainty about the magnitude of that difference. 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:- The downside deviation over 5 years of VanEck Vectors Uranium & Nuclear Energy ETF is 14.1%, which is smaller, thus better compared to the benchmark SPY (14.6%) in the same period.
- During the last 3 years, the downside risk is 12.8%, which is lower, thus better than the value of 14% 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:- Compared with the benchmark SPY (0.64) in the period of the last 5 years, the ratio of return and volatility (Sharpe) of 0.15 of VanEck Vectors Uranium & Nuclear Energy ETF is lower, thus worse.
- Compared with SPY (0.91) in the period of the last 3 years, the ratio of return and volatility (Sharpe) of 0.43 is lower, thus worse.

'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.'

Using this definition on our asset we see for example:- The ratio of annual return and downside deviation over 5 years of VanEck Vectors Uranium & Nuclear Energy ETF is 0.14, which is smaller, thus worse compared to the benchmark SPY (0.58) in the same period.
- Compared with SPY (0.8) in the period of the last 3 years, the excess return divided by the downside deviation of 0.39 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:- Looking at the Downside risk index of 5.71 in the last 5 years of VanEck Vectors Uranium & Nuclear Energy ETF, we see it is relatively larger, thus better in comparison to the benchmark SPY (3.95 )
- Compared with SPY (4 ) in the period of the last 3 years, the Ulcer Index of 3.54 is smaller, 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:- Compared with the benchmark SPY (-19.3 days) in the period of the last 5 years, the maximum DrawDown of -16.4 days of VanEck Vectors Uranium & Nuclear Energy ETF is higher, thus better.
- Compared with SPY (-19.3 days) in the period of the last 3 years, the maximum drop from peak to valley of -11.4 days is higher, thus better.

'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:- Compared with the benchmark SPY (187 days) in the period of the last 5 years, the maximum days under water of 561 days of VanEck Vectors Uranium & Nuclear Energy ETF is higher, thus worse.
- Looking at maximum time in days below previous high water mark in of 162 days in the period of the last 3 years, we see it is relatively larger, thus worse in comparison to SPY (131 days).

'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.'

Using this definition on our asset we see for example:- The average days under water over 5 years of VanEck Vectors Uranium & Nuclear Energy ETF is 152 days, which is greater, thus worse compared to the benchmark SPY (39 days) in the same period.
- Looking at average days below previous high in of 44 days in the period of the last 3 years, we see it is relatively higher, thus worse in comparison to SPY (33 days).
