'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.'

Which means for our asset as example:- Compared with the benchmark SPY (128%) in the period of the last 5 years, the total return, or increase in value of 351.7% of Global X Lithium & Battery Tech ETF is higher, thus better.
- Looking at total return in of 97% in the period of the last 3 years, we see it is relatively larger, thus better in comparison to SPY (44.9%).

'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:- Compared with the benchmark SPY (17.9%) in the period of the last 5 years, the annual return (CAGR) of 35.2% of Global X Lithium & Battery Tech ETF is greater, thus better.
- Compared with SPY (13.2%) in the period of the last 3 years, the annual performance (CAGR) of 25.3% is greater, thus better.

'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.'

Which means for our asset as example:- Looking at the volatility of 28.2% 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 (18.7%)
- Looking at volatility in of 32.6% in the period of the last 3 years, we see it is relatively greater, thus worse in comparison to SPY (22.9%).

'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 deviation over 5 years of Global X Lithium & Battery Tech ETF is 19.2%, which is greater, thus worse compared to the benchmark SPY (13.6%) in the same period.
- Looking at downside volatility in of 22.4% in the period of the last 3 years, we see it is relatively greater, thus worse in comparison to SPY (16.7%).

'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 ratio of return and volatility (Sharpe) of 1.16 in the last 5 years of Global X Lithium & Battery Tech ETF, we see it is relatively larger, thus better in comparison to the benchmark SPY (0.82)
- During the last 3 years, the Sharpe Ratio is 0.7, which is larger, thus better than the value of 0.47 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.'

Using this definition on our asset we see for example:- Looking at the excess return divided by the downside deviation of 1.7 in the last 5 years of Global X Lithium & Battery Tech ETF, we see it is relatively higher, thus better in comparison to the benchmark SPY (1.14)
- Looking at downside risk / excess return profile in of 1.02 in the period of the last 3 years, we see it is relatively higher, thus better in comparison to SPY (0.64).

'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.'

Using this definition on our asset we see for example:- Looking at the Ulcer Ratio of 21 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 (5.59 )
- Compared with SPY (7.15 ) in the period of the last 3 years, the Downside risk index of 23 is higher, 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:- Compared with the benchmark SPY (-33.7 days) in the period of the last 5 years, the maximum drop from peak to valley of -53.9 days of Global X Lithium & Battery Tech ETF is lower, thus worse.
- During the last 3 years, the maximum drop from peak to valley is -51 days, which is lower, thus worse than the value of -33.7 days from the benchmark.

'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.'

Using this definition on our asset we see for example:- Compared with the benchmark SPY (139 days) in the period of the last 5 years, the maximum days under water of 664 days of Global X Lithium & Battery Tech ETF is greater, thus worse.
- Compared with SPY (139 days) in the period of the last 3 years, the maximum time in days below previous high water mark of 618 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.'

Using this definition on our asset we see for example:- The average days below previous high over 5 years of Global X Lithium & Battery Tech ETF is 205 days, which is larger, thus worse compared to the benchmark SPY (33 days) in the same period.
- Looking at average days below previous high in of 269 days in the period of the last 3 years, we see it is relatively greater, thus worse in comparison to SPY (45 days).
