What do these metrics mean? [Read More] [Hide]

TotalReturn:

'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.'

Using this definition on our asset we see for example:
  • Looking at the total return of 47.2% in the last 5 years of Pfizer, we see it is relatively smaller, thus worse in comparison to the benchmark SPY (68.6%)
  • Looking at total return in of 31.2% in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (51%).

CAGR:

'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:
  • Looking at the annual performance (CAGR) of 8% in the last 5 years of Pfizer, we see it is relatively smaller, thus worse in comparison to the benchmark SPY (11%)
  • During the last 3 years, the annual return (CAGR) is 9.5%, which is lower, thus worse than the value of 14.8% from the benchmark.

Volatility:

'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.'

Using this definition on our asset we see for example:
  • Compared with the benchmark SPY (13.5%) in the period of the last 5 years, the historical 30 days volatility of 18.1% of Pfizer is greater, thus worse.
  • Looking at historical 30 days volatility in of 17.1% in the period of the last 3 years, we see it is relatively larger, thus worse in comparison to SPY (12.8%).

DownVol:

'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.'

Which means for our asset as example:
  • The downside volatility over 5 years of Pfizer is 18.5%, which is higher, thus worse compared to the benchmark SPY (14.9%) in the same period.
  • Looking at downside volatility in of 19% in the period of the last 3 years, we see it is relatively greater, thus worse in comparison to SPY (14.7%).

Sharpe:

'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:
  • The risk / return profile (Sharpe) over 5 years of Pfizer is 0.31, which is lower, thus worse compared to the benchmark SPY (0.63) in the same period.
  • During the last 3 years, the ratio of return and volatility (Sharpe) is 0.41, which is lower, thus worse than the value of 0.96 from the benchmark.

Sortino:

'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.'

Using this definition on our asset we see for example:
  • Compared with the benchmark SPY (0.57) in the period of the last 5 years, the ratio of annual return and downside deviation of 0.3 of Pfizer is lower, thus worse.
  • Compared with SPY (0.83) in the period of the last 3 years, the excess return divided by the downside deviation of 0.37 is lower, thus worse.

Ulcer:

'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:
  • Compared with the benchmark SPY (3.99 ) in the period of the last 5 years, the Downside risk index of 8.56 of Pfizer is greater, thus worse.
  • Compared with SPY (4.1 ) in the period of the last 3 years, the Ulcer Index of 7.95 is higher, thus worse.

MaxDD:

'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.'

Which means for our asset as example:
  • The maximum drop from peak to valley over 5 years of Pfizer is -23.9 days, which is lower, thus worse compared to the benchmark SPY (-19.3 days) in the same period.
  • During the last 3 years, the maximum DrawDown is -23.9 days, which is smaller, thus worse than the value of -19.3 days from the benchmark.

MaxDuration:

'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:
  • The maximum days under water over 5 years of Pfizer is 282 days, which is larger, thus worse compared to the benchmark SPY (187 days) in the same period.
  • Compared with SPY (139 days) in the period of the last 3 years, the maximum time in days below previous high water mark of 242 days is higher, thus worse.

AveDuration:

'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:
  • Looking at the average days below previous high of 88 days in the last 5 years of Pfizer, we see it is relatively larger, thus worse in comparison to the benchmark SPY (42 days)
  • Looking at average days under water in of 68 days in the period of the last 3 years, we see it is relatively larger, thus worse in comparison to SPY (36 days).
