'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.'

Using this definition on our asset we see for example:- The total return over 5 years of Pfizer is 56.6%, which is smaller, thus worse compared to the benchmark SPY (62.7%) in the same period.
- Looking at total return in of 46% in the period of the last 3 years, we see it is relatively higher, thus better in comparison to SPY (34.7%).

'Compound annual growth rate (CAGR) is a business and investing specific term for the geometric progression ratio that provides a constant rate of return over the time period. CAGR is not an accounting term, but it is often used to describe some element of the business, for example revenue, units delivered, registered users, etc. CAGR dampens the effect of volatility of periodic returns that can render arithmetic means irrelevant. It is particularly useful to compare growth rates from various data sets of common domain such as revenue growth of companies in the same industry.'

Which means for our asset as example:- The compounded annual growth rate (CAGR) over 5 years of Pfizer is 9.4%, which is lower, thus worse compared to the benchmark SPY (10.2%) in the same period.
- During the last 3 years, the annual return (CAGR) is 13.5%, which is greater, thus better than the value of 10.5% 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.'

Applying this definition to our asset in some examples:- Looking at the historical 30 days volatility of 25.7% in the last 5 years of Pfizer, we see it is relatively higher, thus worse in comparison to the benchmark SPY (20.9%)
- Compared with SPY (24.1%) in the period of the last 3 years, the historical 30 days volatility of 29.3% is larger, thus worse.

'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:- Looking at the downside deviation of 17.5% in the last 5 years of Pfizer, we see it is relatively larger, thus worse in comparison to the benchmark SPY (15.3%)
- During the last 3 years, the downside risk is 19.2%, which is larger, thus worse than the value of 17.6% 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 ratio of return and volatility (Sharpe) over 5 years of Pfizer is 0.27, which is lower, thus worse compared to the benchmark SPY (0.37) in the same period.
- Looking at ratio of return and volatility (Sharpe) in of 0.37 in the period of the last 3 years, we see it is relatively larger, thus better in comparison to SPY (0.33).

'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:- Compared with the benchmark SPY (0.51) in the period of the last 5 years, the excess return divided by the downside deviation of 0.4 of Pfizer is lower, thus worse.
- During the last 3 years, the excess return divided by the downside deviation is 0.57, which is larger, thus better than the value of 0.45 from the benchmark.

'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 Ulcer Index of 13 in the last 5 years of Pfizer, we see it is relatively larger, thus worse in comparison to the benchmark SPY (7.71 )
- Looking at Ulcer Index in of 12 in the period of the last 3 years, we see it is relatively greater, thus worse in comparison to SPY (9.08 ).

'Maximum drawdown is defined as the peak-to-trough decline of an investment during a specific period. It is usually quoted as a percentage of the peak value. The maximum drawdown can be calculated based on absolute returns, in order to identify strategies that suffer less during market downturns, such as low-volatility strategies. However, the maximum drawdown can also be calculated based on returns relative to a benchmark index, for identifying strategies that show steady outperformance over time.'

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 DrawDown of -35.4 days of Pfizer is lower, thus worse.
- Looking at maximum drop from peak to valley in of -29.3 days in the period of the last 3 years, we see it is relatively greater, thus better in comparison to SPY (-33.7 days).

'The Maximum 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. It is the length of time the account was in the Max Drawdown. A Max Drawdown measures a retrenchment from when an equity curve reaches a new high. It’s the maximum an account lost during that retrenchment. This method is applied because a valley can’t be measured until a new high occurs. Once the new high is reached, the percentage change from the old high to the bottom of the largest trough is recorded.'

Which means for our asset as example:- Compared with the benchmark SPY (189 days) in the period of the last 5 years, the maximum days under water of 503 days of Pfizer is greater, thus worse.
- Compared with SPY (189 days) in the period of the last 3 years, the maximum time in days below previous high water mark of 201 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.'

Which means for our asset as example:- The average days below previous high over 5 years of Pfizer is 142 days, which is greater, thus worse compared to the benchmark SPY (46 days) in the same period.
- Looking at average days under water in of 77 days in the period of the last 3 years, we see it is relatively higher, thus worse in comparison to SPY (45 days).

- Note that yearly returns do not equal the sum of monthly returns due to compounding.
- Performance results of Pfizer 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.
