'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.'

Which means for our asset as example:- Compared with the benchmark SPY (98.3%) in the period of the last 5 years, the total return of % of BlackRock Future Climate and Sustainable Economy ETF is lower, thus worse.
- During the last 3 years, the total return is -17.2%, which is lower, thus worse than the value of 27.2% from the benchmark.

'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:- Compared with the benchmark SPY (14.7%) in the period of the last 5 years, the annual return (CAGR) of % of BlackRock Future Climate and Sustainable Economy ETF is lower, thus worse.
- Looking at annual return (CAGR) in of -6.1% in the period of the last 3 years, we see it is relatively smaller, thus worse in comparison to SPY (8.4%).

'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:- Compared with the benchmark SPY (20.9%) in the period of the last 5 years, the historical 30 days volatility of % of BlackRock Future Climate and Sustainable Economy ETF is lower, thus better.
- Looking at 30 days standard deviation in of 17.7% in the period of the last 3 years, we see it is relatively higher, thus worse in comparison to SPY (17.7%).

'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.'

Which means for our asset as example:- Looking at the downside risk of % in the last 5 years of BlackRock Future Climate and Sustainable Economy ETF, we see it is relatively lower, thus better in comparison to the benchmark SPY (14.9%)
- Looking at downside volatility in of 12.6% in the period of the last 3 years, we see it is relatively higher, thus worse in comparison to SPY (12.4%).

'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.'

Which means for our asset as example:- Compared with the benchmark SPY (0.58) in the period of the last 5 years, the ratio of return and volatility (Sharpe) of of BlackRock Future Climate and Sustainable Economy ETF is lower, thus worse.
- Looking at Sharpe Ratio in of -0.49 in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (0.33).

'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.'

Which means for our asset as example:- Compared with the benchmark SPY (0.82) in the period of the last 5 years, the excess return divided by the downside deviation of of BlackRock Future Climate and Sustainable Economy ETF is smaller, thus worse.
- Looking at ratio of annual return and downside deviation in of -0.68 in the period of the last 3 years, we see it is relatively smaller, thus worse in comparison to SPY (0.47).

'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.'

Which means for our asset as example:- Looking at the Ulcer Index of in the last 5 years of BlackRock Future Climate and Sustainable Economy ETF, we see it is relatively smaller, thus better in comparison to the benchmark SPY (9.32 )
- During the last 3 years, the Ulcer Index is 19 , which is higher, thus worse than the value of 10 from the benchmark.

'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.'

Applying this definition to our asset in some examples:- Compared with the benchmark SPY (-33.7 days) in the period of the last 5 years, the maximum reduction from previous high of days of BlackRock Future Climate and Sustainable Economy ETF is smaller, thus worse.
- Looking at maximum DrawDown in of -32.3 days in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (-24.5 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:- The maximum days under water over 5 years of BlackRock Future Climate and Sustainable Economy ETF is days, which is lower, thus better compared to the benchmark SPY (488 days) in the same period.
- During the last 3 years, the maximum days under water is 700 days, which is larger, thus worse than the value of 488 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.'

Which means for our asset as example:- Looking at the average days below previous high of days in the last 5 years of BlackRock Future Climate and Sustainable Economy ETF, we see it is relatively lower, thus better in comparison to the benchmark SPY (123 days)
- Looking at average days under water in of 330 days in the period of the last 3 years, we see it is relatively larger, thus worse in comparison to SPY (177 days).
