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.'

Which means for our asset as example:
  • Looking at the total return, or increase in value of 65.1% in the last 5 years of Pfizer, we see it is relatively smaller, thus worse in comparison to the benchmark SPY (66.1%)
  • During the last 3 years, the total return is 29.6%, which is smaller, thus worse than the value of 46.2% from the benchmark.

CAGR:

'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 return (CAGR) of 10.6% in the last 5 years of Pfizer, we see it is relatively lower, thus worse in comparison to the benchmark SPY (10.7%)
  • During the last 3 years, the annual performance (CAGR) is 9.1%, which is lower, thus worse than the value of 13.5% 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 (13.4%) in the period of the last 5 years, the volatility of 17.6% of Pfizer is higher, thus worse.
  • Compared with SPY (12.3%) in the period of the last 3 years, the 30 days standard deviation of 17% is higher, thus worse.

DownVol:

'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:
  • Compared with the benchmark SPY (14.6%) in the period of the last 5 years, the downside deviation of 17.7% of Pfizer is greater, thus worse.
  • Compared with SPY (13.9%) in the period of the last 3 years, the downside volatility of 17.8% is greater, thus worse.

Sharpe:

'The Sharpe ratio is the measure of risk-adjusted return of a financial portfolio. Sharpe ratio is a measure of excess portfolio return over the risk-free rate relative to its standard deviation. Normally, the 90-day Treasury bill rate is taken as the proxy for risk-free rate. A portfolio with a higher Sharpe ratio is considered superior relative to its peers. The measure was named after William F Sharpe, a Nobel laureate and professor of finance, emeritus at Stanford University.'

Applying this definition to our asset in some examples:
  • Compared with the benchmark SPY (0.61) in the period of the last 5 years, the Sharpe Ratio of 0.46 of Pfizer is lower, thus worse.
  • During the last 3 years, the risk / return profile (Sharpe) is 0.39, which is lower, thus worse than the value of 0.9 from the benchmark.

Sortino:

'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.'

Applying this definition to our asset in some examples:
  • Looking at the ratio of annual return and downside deviation of 0.46 in the last 5 years of Pfizer, we see it is relatively lower, thus worse in comparison to the benchmark SPY (0.56)
  • During the last 3 years, the downside risk / excess return profile is 0.37, which is lower, thus worse than the value of 0.8 from the benchmark.

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.'

Applying this definition to our asset in some examples:
  • Looking at the Ulcer Ratio of 7.18 in the last 5 years of Pfizer, we see it is relatively greater, thus worse in comparison to the benchmark SPY (3.99 )
  • Looking at Downside risk index in of 7.27 in the period of the last 3 years, we see it is relatively greater, thus worse in comparison to SPY (4.04 ).

MaxDD:

'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.'

Which means for our asset as example:
  • Looking at the maximum reduction from previous high of -19.2 days in the last 5 years of Pfizer, we see it is relatively higher, thus better in comparison to the benchmark SPY (-19.3 days)
  • During the last 3 years, the maximum reduction from previous high is -19.2 days, which is larger, thus better than the value of -19.3 days from the benchmark.

MaxDuration:

'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.'

Applying this definition to our asset in some examples:
  • Looking at the maximum days under water of 282 days in the last 5 years of Pfizer, we see it is relatively higher, thus worse 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 282 days is higher, thus worse.

AveDuration:

'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.'

Using this definition on our asset we see for example:
  • Looking at the average days under water of 77 days in the last 5 years of Pfizer, we see it is relatively higher, thus worse in comparison to the benchmark SPY (41 days)
  • Looking at average time in days below previous high water mark in of 87 days in the period of the last 3 years, we see it is relatively higher, thus worse in comparison to SPY (36 days).
