'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 (80.1%) in the period of the last 5 years, the total return of 63.6% of Global X Lithium & Battery Tech ETF is lower, thus worse.
- During the last 3 years, the total return is -7.9%, which is lower, thus worse than the value of 30.8% 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.'

Using this definition on our asset we see for example:- Looking at the annual performance (CAGR) of 10.4% in the last 5 years of Global X Lithium & Battery Tech ETF, we see it is relatively lower, thus worse in comparison to the benchmark SPY (12.5%)
- Looking at annual return (CAGR) in of -2.7% in the period of the last 3 years, we see it is relatively smaller, thus worse in comparison to SPY (9.4%).

'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 (21.3%) in the period of the last 5 years, the volatility of 34.1% of Global X Lithium & Battery Tech ETF is higher, thus worse.
- Looking at volatility in of 33% in the period of the last 3 years, we see it is relatively higher, thus worse in comparison to SPY (17.6%).

'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:- Compared with the benchmark SPY (15.3%) in the period of the last 5 years, the downside deviation of 23.7% of Global X Lithium & Battery Tech ETF is larger, thus worse.
- During the last 3 years, the downside volatility is 22.9%, which is larger, 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.'

Applying this definition to our asset in some examples:- Looking at the Sharpe Ratio of 0.23 in the last 5 years of Global X Lithium & Battery Tech ETF, we see it is relatively lower, thus worse in comparison to the benchmark SPY (0.47)
- Compared with SPY (0.39) in the period of the last 3 years, the Sharpe Ratio of -0.16 is lower, thus worse.

'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:- Compared with the benchmark SPY (0.66) in the period of the last 5 years, the ratio of annual return and downside deviation of 0.33 of Global X Lithium & Battery Tech ETF is smaller, thus worse.
- Compared with SPY (0.56) in the period of the last 3 years, the ratio of annual return and downside deviation of -0.23 is lower, thus worse.

'The ulcer index is a stock market risk measure or technical analysis indicator devised by Peter Martin in 1987, and published by him and Byron McCann in their 1989 book The Investors Guide to Fidelity Funds. It's designed as a measure of volatility, but only volatility in the downward direction, i.e. the amount of drawdown or retracement occurring over a period. Other volatility measures like standard deviation treat up and down movement equally, but a trader doesn't mind upward movement, it's the downside that causes stress and stomach ulcers that the index's name suggests.'

Applying this definition to our asset in some examples:- Looking at the Downside risk index of 22 in the last 5 years of Global X Lithium & Battery Tech ETF, we see it is relatively greater, thus worse in comparison to the benchmark SPY (9.43 )
- During the last 3 years, the Downside risk index is 26 , which is higher, thus worse than the value of 10 from the benchmark.

'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.'

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 drop from peak to valley of -50.2 days of Global X Lithium & Battery Tech ETF is smaller, thus worse.
- Compared with SPY (-24.5 days) in the period of the last 3 years, the maximum reduction from previous high of -50.2 days is lower, thus worse.

'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 Global X Lithium & Battery Tech ETF is 516 days, which is higher, thus worse compared to the benchmark SPY (478 days) in the same period.
- During the last 3 years, the maximum days below previous high is 516 days, which is larger, thus worse than the value of 478 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.'

Applying this definition to our asset in some examples:- Compared with the benchmark SPY (118 days) in the period of the last 5 years, the average days under water of 158 days of Global X Lithium & Battery Tech ETF is greater, thus worse.
- Compared with SPY (173 days) in the period of the last 3 years, the average days below previous high of 194 days is higher, thus worse.
