'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:- The total return over 5 years of iShares Genomics Immunology and Healthcare ETF is %, which is lower, thus worse compared to the benchmark SPY (97%) in the same period.
- During the last 3 years, the total return, or increase in value is -45.2%, which is lower, thus worse than the value of 39.3% 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 compounded annual growth rate (CAGR) of % in the last 5 years of iShares Genomics Immunology and Healthcare ETF, we see it is relatively smaller, thus worse in comparison to the benchmark SPY (14.6%)
- Compared with SPY (11.7%) in the period of the last 3 years, the compounded annual growth rate (CAGR) of -18.2% 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:- Looking at the 30 days standard deviation of % in the last 5 years of iShares Genomics Immunology and Healthcare ETF, we see it is relatively smaller, thus better in comparison to the benchmark SPY (20.9%)
- Looking at volatility in of 31.8% in the period of the last 3 years, we see it is relatively greater, thus worse in comparison to SPY (17.5%).

'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 volatility of % in the last 5 years of iShares Genomics Immunology and Healthcare ETF, we see it is relatively lower, thus better in comparison to the benchmark SPY (15%)
- Compared with SPY (12.1%) in the period of the last 3 years, the downside volatility of 22.8% is greater, thus worse.

'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.'

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 Sharpe Ratio of of iShares Genomics Immunology and Healthcare ETF is lower, thus worse.
- Compared with SPY (0.53) in the period of the last 3 years, the risk / return profile (Sharpe) of -0.65 is smaller, thus worse.

'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.'

Applying this definition to our asset in some examples:- Compared with the benchmark SPY (0.8) in the period of the last 5 years, the downside risk / excess return profile of of iShares Genomics Immunology and Healthcare ETF is lower, thus worse.
- Looking at downside risk / excess return profile in of -0.91 in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (0.76).

'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:- Looking at the Downside risk index of in the last 5 years of iShares Genomics Immunology and Healthcare ETF, we see it is relatively lower, thus better in comparison to the benchmark SPY (9.33 )
- During the last 3 years, the Ulcer Ratio is 45 , 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:- Looking at the maximum DrawDown of days in the last 5 years of iShares Genomics Immunology and Healthcare ETF, we see it is relatively smaller, thus worse in comparison to the benchmark SPY (-33.7 days)
- During the last 3 years, the maximum DrawDown is -68.3 days, which is smaller, thus worse than the value of -24.5 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). Many assume Max DD Duration is the length of time between new highs during which the Max DD (magnitude) occurred. But that isn’t always the case. The Max DD duration is the longest time between peaks, period. So it could be the time when the program also had its biggest peak to valley loss (and usually is, because the program needs a long time to recover from the largest loss), but it doesn’t have to be'

Which means for our asset as example:- The maximum days below previous high over 5 years of iShares Genomics Immunology and Healthcare ETF is days, which is smaller, thus better compared to the benchmark SPY (488 days) in the same period.
- Compared with SPY (488 days) in the period of the last 3 years, the maximum time in days below previous high water mark of 623 days is larger, 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.'

Which means for our asset as example:- The average days below previous high over 5 years of iShares Genomics Immunology and Healthcare ETF is days, which is lower, thus better compared to the benchmark SPY (123 days) in the same period.
- During the last 3 years, the average days under water is 265 days, which is greater, thus worse than the value of 181 days from the benchmark.
