'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:- Looking at the total return, or performance of -7.7% in the last 5 years of BioMarin Pharmaceutical, we see it is relatively lower, thus worse in comparison to the benchmark SPY (61.3%)
- Compared with SPY (31.6%) in the period of the last 3 years, the total return of 25.7% is smaller, thus worse.

'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.'

Which means for our asset as example:- Compared with the benchmark SPY (10%) in the period of the last 5 years, the annual return (CAGR) of -1.6% of BioMarin Pharmaceutical is lower, thus worse.
- Compared with SPY (9.6%) in the period of the last 3 years, the annual performance (CAGR) of 7.9% 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.'

Using this definition on our asset we see for example:- The volatility over 5 years of BioMarin Pharmaceutical is 38.1%, which is greater, thus worse compared to the benchmark SPY (20.8%) in the same period.
- Compared with SPY (24%) in the period of the last 3 years, the volatility of 41.4% is larger, 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:- The downside volatility over 5 years of BioMarin Pharmaceutical is 28.4%, which is larger, thus worse compared to the benchmark SPY (15.3%) in the same period.
- Looking at downside deviation in of 31.7% in the period of the last 3 years, we see it is relatively greater, thus worse in comparison to SPY (17.6%).

'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:- The risk / return profile (Sharpe) over 5 years of BioMarin Pharmaceutical is -0.11, which is lower, thus worse compared to the benchmark SPY (0.36) in the same period.
- During the last 3 years, the Sharpe Ratio is 0.13, which is smaller, thus worse than the value of 0.3 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.'

Applying this definition to our asset in some examples:- Looking at the downside risk / excess return profile of -0.14 in the last 5 years of BioMarin Pharmaceutical, we see it is relatively smaller, thus worse in comparison to the benchmark SPY (0.49)
- Looking at ratio of annual return and downside deviation in of 0.17 in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (0.4).

'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:- The Ulcer Ratio over 5 years of BioMarin Pharmaceutical is 28 , which is greater, thus worse compared to the benchmark SPY (7.61 ) in the same period.
- Looking at Downside risk index in of 32 in the period of the last 3 years, we see it is relatively higher, thus worse in comparison to SPY (8.93 ).

'Maximum drawdown measures the loss in any losing period during a fund’s investment record. It is defined as the percent retrenchment from a fund’s peak value to the fund’s valley value. The drawdown is in effect from the time the fund’s retrenchment begins until a new fund high is reached. The maximum drawdown encompasses both the period from the fund’s peak to the fund’s valley (length), and the time from the fund’s valley to a new fund high (recovery). It measures the largest percentage drawdown that has occurred in any fund’s data record.'

Which means for our asset as example:- The maximum DrawDown over 5 years of BioMarin Pharmaceutical is -45.4 days, which is lower, thus worse compared to the benchmark SPY (-33.7 days) in the same period.
- Looking at maximum reduction from previous high in of -45.4 days in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (-33.7 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:- Looking at the maximum days below previous high of 553 days in the last 5 years of BioMarin Pharmaceutical, we see it is relatively greater, thus worse in comparison to the benchmark SPY (185 days)
- Looking at maximum days under water in of 553 days in the period of the last 3 years, we see it is relatively greater, thus worse in comparison to SPY (185 days).

'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:- Compared with the benchmark SPY (46 days) in the period of the last 5 years, the average days under water of 204 days of BioMarin Pharmaceutical is greater, thus worse.
- During the last 3 years, the average days below previous high is 217 days, which is higher, thus worse than the value of 44 days from the benchmark.
