'Total return is the amount of value an investor earns from a security over a specific period, typically one year, when all distributions are reinvested. Total return is expressed as a percentage of the amount invested. For example, a total return of 20% means the security increased by 20% of its original value due to a price increase, distribution of dividends (if a stock), coupons (if a bond) or capital gains (if a fund). Total return is a strong measure of an investment’s overall performance.'

Applying this definition to our asset in some examples:- Compared with the benchmark SPY (68.1%) in the period of the last 5 years, the total return, or increase in value of 20.3% of Global X Robotics & Artificial Intelligence ETF is smaller, thus worse.
- During the last 3 years, the total return is 19.5%, which is smaller, thus worse than the value of 47% 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:- Compared with the benchmark SPY (11%) in the period of the last 5 years, the compounded annual growth rate (CAGR) of 3.8% of Global X Robotics & Artificial Intelligence ETF is lower, thus worse.
- Compared with SPY (13.7%) in the period of the last 3 years, the compounded annual growth rate (CAGR) of 6.1% is smaller, thus worse.

'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.'

Which means for our asset as example:- The 30 days standard deviation over 5 years of Global X Robotics & Artificial Intelligence ETF is 29.2%, which is larger, thus worse compared to the benchmark SPY (21.4%) in the same period.
- Compared with SPY (18.7%) in the period of the last 3 years, the historical 30 days volatility of 27.4% is greater, thus worse.

'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:- Looking at the downside risk of 20.8% in the last 5 years of Global X Robotics & Artificial Intelligence ETF, we see it is relatively greater, thus worse in comparison to the benchmark SPY (15.4%)
- Looking at downside volatility in of 19.3% in the period of the last 3 years, we see it is relatively larger, thus worse in comparison to SPY (13.3%).

'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:- The ratio of return and volatility (Sharpe) over 5 years of Global X Robotics & Artificial Intelligence ETF is 0.04, which is lower, thus worse compared to the benchmark SPY (0.4) in the same period.
- Compared with SPY (0.6) in the period of the last 3 years, the ratio of return and volatility (Sharpe) of 0.13 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.'

Applying this definition to our asset in some examples:- The downside risk / excess return profile over 5 years of Global X Robotics & Artificial Intelligence ETF is 0.06, which is lower, thus worse compared to the benchmark SPY (0.55) in the same period.
- Looking at downside risk / excess return profile in of 0.19 in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (0.84).

'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 Ulcer Index of 24 in the last 5 years of Global X Robotics & Artificial Intelligence ETF, we see it is relatively greater, thus worse in comparison to the benchmark SPY (9.45 )
- During the last 3 years, the Downside risk index is 28 , which is greater, thus worse than the value of 10 from the benchmark.

'A maximum drawdown is the maximum loss from a peak to a trough of a portfolio, before a new peak is attained. Maximum Drawdown is an indicator of downside risk over a specified time period. It can be used both as a stand-alone measure or as an input into other metrics such as 'Return over Maximum Drawdown' and the Calmar Ratio. Maximum Drawdown is expressed in percentage terms.'

Using this definition on our asset we see for example:- The maximum DrawDown over 5 years of Global X Robotics & Artificial Intelligence ETF is -55.5 days, which is lower, thus worse compared to the benchmark SPY (-33.7 days) in the same period.
- During the last 3 years, the maximum DrawDown is -55.5 days, which is lower, thus worse than the value of -24.5 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.'

Which means for our asset as example:- The maximum days below previous high over 5 years of Global X Robotics & Artificial Intelligence ETF is 493 days, which is larger, thus worse compared to the benchmark SPY (351 days) in the same period.
- Looking at maximum days under water in of 389 days in the period of the last 3 years, we see it is relatively larger, thus worse in comparison to SPY (351 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.'

Which means for our asset as example:- Looking at the average time in days below previous high water mark of 175 days in the last 5 years of Global X Robotics & Artificial Intelligence ETF, we see it is relatively larger, thus worse in comparison to the benchmark SPY (78 days)
- Looking at average time in days below previous high water mark in of 124 days in the period of the last 3 years, we see it is relatively greater, thus worse in comparison to SPY (101 days).
