'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 (63%) in the period of the last 5 years, the total return of 214.6% of O'Reilly Automotive is higher, thus better.
- Compared with SPY (33.5%) in the period of the last 3 years, the total return, or performance of 95.7% is larger, thus better.

'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.'

Which means for our asset as example:- Looking at the annual performance (CAGR) of 25.8% in the last 5 years of O'Reilly Automotive, we see it is relatively higher, thus better in comparison to the benchmark SPY (10.3%)
- Looking at compounded annual growth rate (CAGR) in of 25% in the period of the last 3 years, we see it is relatively larger, thus better in comparison to SPY (10.1%).

'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 (21.6%) in the period of the last 5 years, the volatility of 29.3% of O'Reilly Automotive is higher, thus worse.
- Looking at historical 30 days volatility in of 31.9% in the period of the last 3 years, we see it is relatively higher, thus worse in comparison to SPY (25.1%).

'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.'

Applying this definition to our asset in some examples:- The downside risk over 5 years of O'Reilly Automotive is 20.5%, which is higher, thus worse compared to the benchmark SPY (15.6%) in the same period.
- During the last 3 years, the downside deviation is 23%, which is larger, thus worse than the value of 18.1% from the benchmark.

'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.'

Which means for our asset as example:- The risk / return profile (Sharpe) over 5 years of O'Reilly Automotive is 0.8, which is greater, thus better compared to the benchmark SPY (0.36) in the same period.
- Looking at Sharpe Ratio in of 0.71 in the period of the last 3 years, we see it is relatively higher, thus better in comparison to SPY (0.3).

'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 O'Reilly Automotive is 1.13, which is larger, thus better compared to the benchmark SPY (0.5) in the same period.
- Compared with SPY (0.42) in the period of the last 3 years, the excess return divided by the downside deviation of 0.98 is larger, thus better.

'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.'

Using this definition on our asset we see for example:- Looking at the Downside risk index of 7.69 in the last 5 years of O'Reilly Automotive, we see it is relatively lower, thus better in comparison to the benchmark SPY (8.88 )
- During the last 3 years, the Ulcer Index is 7.96 , which is lower, thus better than the value of 11 from the benchmark.

'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.'

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 drop from peak to valley of -42 days of O'Reilly Automotive is lower, thus worse.
- Compared with SPY (-33.7 days) in the period of the last 3 years, the maximum DrawDown of -37.8 days is lower, thus worse.

'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 168 days in the last 5 years of O'Reilly Automotive, we see it is relatively lower, thus better in comparison to the benchmark SPY (273 days)
- Looking at maximum time in days below previous high water mark in of 127 days in the period of the last 3 years, we see it is relatively lower, thus better in comparison to SPY (273 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:- Looking at the average days under water of 41 days in the last 5 years of O'Reilly Automotive, we see it is relatively lower, thus better in comparison to the benchmark SPY (57 days)
- During the last 3 years, the average time in days below previous high water mark is 33 days, which is smaller, thus better than the value of 73 days from the benchmark.
