'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:- Looking at the total return, or performance of 53.7% in the last 5 years of iShares Global Healthcare ETF, we see it is relatively smaller, thus worse in comparison to the benchmark SPY (88%)
- Looking at total return in of 32.4% in the period of the last 3 years, we see it is relatively smaller, thus worse in comparison to SPY (39.5%).

'Compound annual growth rate (CAGR) is a business and investing specific term for the geometric progression ratio that provides a constant rate of return over the time period. CAGR is not an accounting term, but it is often used to describe some element of the business, for example revenue, units delivered, registered users, etc. CAGR dampens the effect of volatility of periodic returns that can render arithmetic means irrelevant. It is particularly useful to compare growth rates from various data sets of common domain such as revenue growth of companies in the same industry.'

Applying this definition to our asset in some examples:- Looking at the annual performance (CAGR) of 9% in the last 5 years of iShares Global Healthcare ETF, we see it is relatively smaller, thus worse in comparison to the benchmark SPY (13.5%)
- Compared with SPY (11.7%) in the period of the last 3 years, the compounded annual growth rate (CAGR) of 9.8% is lower, thus worse.

'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.'

Which means for our asset as example:- Compared with the benchmark SPY (18.8%) in the period of the last 5 years, the volatility of 17.4% of iShares Global Healthcare ETF is lower, thus better.
- Looking at historical 30 days volatility in of 19.7% in the period of the last 3 years, we see it is relatively lower, thus better in comparison to SPY (22.3%).

'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.'

Using this definition on our asset we see for example:- Looking at the downside risk of 12.4% in the last 5 years of iShares Global Healthcare ETF, we see it is relatively smaller, thus better in comparison to the benchmark SPY (13.7%)
- Looking at downside volatility in of 14.2% in the period of the last 3 years, we see it is relatively lower, thus better in comparison to SPY (16.5%).

'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:- Compared with the benchmark SPY (0.58) in the period of the last 5 years, the risk / return profile (Sharpe) of 0.37 of iShares Global Healthcare ETF is smaller, thus worse.
- Compared with SPY (0.41) in the period of the last 3 years, the Sharpe Ratio of 0.37 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 (0.8) in the period of the last 5 years, the ratio of annual return and downside deviation of 0.52 of iShares Global Healthcare 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 0.51 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:- Compared with the benchmark SPY (5.79 ) in the period of the last 5 years, the Downside risk index of 5.46 of iShares Global Healthcare ETF is lower, thus better.
- Looking at Downside risk index in of 5.52 in the period of the last 3 years, we see it is relatively smaller, thus better in comparison to SPY (7.08 ).

'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.'

Which means for our asset as example:- The maximum drop from peak to valley over 5 years of iShares Global Healthcare ETF is -27.4 days, which is greater, thus better compared to the benchmark SPY (-33.7 days) in the same period.
- During the last 3 years, the maximum drop from peak to valley is -27.4 days, which is greater, thus better than the value of -33.7 days from the benchmark.

'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.'

Which means for our asset as example:- Compared with the benchmark SPY (139 days) in the period of the last 5 years, the maximum days below previous high of 188 days of iShares Global Healthcare ETF is greater, thus worse.
- During the last 3 years, the maximum days below previous high is 187 days, which is higher, thus worse than the value of 139 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.'

Using this definition on our asset we see for example:- Compared with the benchmark SPY (37 days) in the period of the last 5 years, the average days under water of 58 days of iShares Global Healthcare ETF is higher, thus worse.
- Looking at average time in days below previous high water mark in of 55 days in the period of the last 3 years, we see it is relatively larger, thus worse in comparison to SPY (45 days).
