'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.'

Which means for our asset as example:- The total return, or performance over 5 years of Exelon is 85.2%, which is larger, thus better compared to the benchmark SPY (58.9%) in the same period.
- During the last 3 years, the total return, or increase in value is 38.1%, which is larger, thus better than the value of 33.9% from the benchmark.

'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.'

Applying this definition to our asset in some examples:- Compared with the benchmark SPY (9.7%) in the period of the last 5 years, the annual performance (CAGR) of 13.1% of Exelon is larger, thus better.
- During the last 3 years, the annual performance (CAGR) is 11.3%, which is higher, thus better than the value of 10.2% from the benchmark.

'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.'

Which means for our asset as example:- Compared with the benchmark SPY (21.6%) in the period of the last 5 years, the historical 30 days volatility of 28% of Exelon is higher, thus worse.
- Looking at volatility in of 33.7% in the period of the last 3 years, we see it is relatively greater, thus worse in comparison to SPY (25%).

'The downside volatility is similar to the volatility, or standard deviation, but only takes losing/negative periods into account.'

Using this definition on our asset we see for example:- Compared with the benchmark SPY (15.7%) in the period of the last 5 years, the downside volatility of 19.4% of Exelon is larger, thus worse.
- Compared with SPY (18.1%) in the period of the last 3 years, the downside volatility of 23.2% is larger, thus worse.

'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 (0.33) in the period of the last 5 years, the ratio of return and volatility (Sharpe) of 0.38 of Exelon is greater, thus better.
- Looking at risk / return profile (Sharpe) in of 0.26 in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (0.31).

'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.'

Which means for our asset as example:- Compared with the benchmark SPY (0.46) in the period of the last 5 years, the ratio of annual return and downside deviation of 0.55 of Exelon is greater, thus better.
- Looking at downside risk / excess return profile in of 0.38 in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (0.43).

'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.'

Using this definition on our asset we see for example:- The Ulcer Ratio over 5 years of Exelon is 12 , which is higher, thus worse compared to the benchmark SPY (8.91 ) in the same period.
- Compared with SPY (11 ) in the period of the last 3 years, the Downside risk index of 15 is larger, thus worse.

'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:- The maximum reduction from previous high over 5 years of Exelon is -40 days, which is smaller, thus worse compared to the benchmark SPY (-33.7 days) in the same period.
- Looking at maximum drop from peak to valley in of -40 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:- Compared with the benchmark SPY (271 days) in the period of the last 5 years, the maximum days below previous high of 369 days of Exelon is higher, thus worse.
- Looking at maximum time in days below previous high water mark in of 369 days in the period of the last 3 years, we see it is relatively greater, thus worse in comparison to SPY (271 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.'

Applying this definition to our asset in some examples:- Compared with the benchmark SPY (60 days) in the period of the last 5 years, the average days below previous high of 93 days of Exelon is greater, thus worse.
- Looking at average 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 larger, thus worse in comparison to SPY (72 days).

- Note that yearly returns do not equal the sum of monthly returns due to compounding.
- Performance results of Exelon are hypothetical, do not account for slippage, fees or taxes, and are based on backtesting, which has many inherent limitations, some of which are described in our Terms of Use.
