'Total return, when measuring performance, is the actual rate of return of an investment or a pool of investments over a given evaluation period. Total return includes interest, capital gains, dividends and distributions realized over a given period of time. Total return accounts for two categories of return: income including interest paid by fixed-income investments, distributions or dividends and capital appreciation, representing the change in the market price of an asset.'

Applying this definition to our asset in some examples:- Looking at the total return, or performance of 34.5% in the last 5 years of Exelon, we see it is relatively lower, thus worse in comparison to the benchmark SPY (57.4%)
- Looking at total return, or increase in value in of 18% in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (32.9%).

'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 (9.5%) in the period of the last 5 years, the annual return (CAGR) of 6.1% of Exelon is lower, thus worse.
- Looking at compounded annual growth rate (CAGR) in of 5.7% in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (10%).

'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.'

Applying this definition to our asset in some examples:- The 30 days standard deviation over 5 years of Exelon is 26.8%, which is larger, thus worse compared to the benchmark SPY (18.7%) in the same period.
- During the last 3 years, the historical 30 days volatility is 29.4%, which is greater, thus worse than the value of 21.5% from the benchmark.

'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 18.8% in the last 5 years of Exelon, we see it is relatively higher, thus worse in comparison to the benchmark SPY (13.6%)
- Looking at downside volatility in of 20.4% in the period of the last 3 years, we see it is relatively larger, thus worse in comparison to SPY (15.7%).

'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.'

Using this definition on our asset we see for example:- Compared with the benchmark SPY (0.37) in the period of the last 5 years, the Sharpe Ratio of 0.13 of Exelon is lower, thus worse.
- Looking at ratio of return and volatility (Sharpe) in of 0.11 in the period of the last 3 years, we see it is relatively smaller, thus worse in comparison to SPY (0.35).

'The Sortino ratio measures the risk-adjusted return of an investment asset, portfolio, or strategy. It is a modification of the Sharpe ratio but penalizes only those returns falling below a user-specified target or required rate of return, while the Sharpe ratio penalizes both upside and downside volatility equally. Though both ratios measure an investment's risk-adjusted return, they do so in significantly different ways that will frequently lead to differing conclusions as to the true nature of the investment's return-generating efficiency. The Sortino ratio is used as a way to compare the risk-adjusted performance of programs with differing risk and return profiles. In general, risk-adjusted returns seek to normalize the risk across programs and then see which has the higher return unit per risk.'

Using this definition on our asset we see for example:- The excess return divided by the downside deviation over 5 years of Exelon is 0.19, which is lower, thus worse compared to the benchmark SPY (0.52) in the same period.
- Looking at ratio of annual return and downside deviation in of 0.16 in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (0.48).

'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 Exelon is 9.27 , which is higher, thus worse compared to the benchmark SPY (5.8 ) in the same period.
- During the last 3 years, the Ulcer Ratio is 9.32 , which is larger, thus worse than the value of 6.84 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.'

Which means for our asset as example:- Looking at the maximum drop from peak to valley of -40 days in the last 5 years of Exelon, we see it is relatively lower, thus worse in comparison to the benchmark SPY (-33.7 days)
- During the last 3 years, the maximum reduction from previous high is -40 days, which is lower, thus worse 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.'

Applying this definition to our asset in some examples:- Looking at the maximum days below previous high of 169 days in the last 5 years of Exelon, we see it is relatively smaller, thus better in comparison to the benchmark SPY (187 days)
- Compared with SPY (139 days) in the period of the last 3 years, the maximum days under water of 169 days is higher, thus worse.

'The Average Drawdown Duration is an extension of the Maximum Drawdown. However, this metric does not explain the drawdown in dollars or percentages, rather in days, weeks, or months. 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.'

Applying this definition to our asset in some examples:- The average days below previous high over 5 years of Exelon is 49 days, which is higher, thus worse compared to the benchmark SPY (43 days) in the same period.
- Looking at average days below previous high in of 45 days in the period of the last 3 years, we see it is relatively higher, thus worse in comparison to SPY (38 days).
