Statistics (YTD)

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

TotalReturn:

'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.'

Applying this definition to our asset in some examples:
  • Compared with the benchmark SPY (59.9%) in the period of the last 5 years, the total return, or performance of 59.9% of SPDR S&P 500 is higher, thus better.
  • During the last 3 years, the total return is 34.2%, which is higher, thus better than the value of 34.2% 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.'

Applying this definition to our asset in some examples:
  • The annual performance (CAGR) over 5 years of SPDR S&P 500 is 9.8%, which is greater, thus better compared to the benchmark SPY (9.8%) in the same period.
  • Looking at annual return (CAGR) in of 10.3% in the period of the last 3 years, we see it is relatively larger, thus better in comparison to SPY (10.3%).

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.'

Which means for our asset as example:
  • The volatility over 5 years of SPDR S&P 500 is 18.7%, which is larger, thus worse compared to the benchmark SPY (18.7%) in the same period.
  • Compared with SPY (21.5%) in the period of the last 3 years, the volatility of 21.5% is higher, thus worse.

DownVol:

'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.'

Using this definition on our asset we see for example:
  • The downside deviation over 5 years of SPDR S&P 500 is 13.6%, which is higher, thus worse compared to the benchmark SPY (13.6%) in the same period.
  • Looking at downside deviation in of 15.7% in the period of the last 3 years, we see it is relatively larger, thus worse in comparison to SPY (15.7%).

Sharpe:

'The Sharpe ratio was developed by Nobel laureate William F. Sharpe, and is used to help investors understand the return of an investment compared to its risk. The ratio is the average return earned in excess of the risk-free rate per unit of volatility or total risk. Subtracting the risk-free rate from the mean return allows an investor to better isolate the profits associated with risk-taking activities. One intuition of this calculation is that a portfolio engaging in 'zero risk' investments, such as the purchase of U.S. Treasury bills (for which the expected return is the risk-free rate), has a Sharpe ratio of exactly zero. Generally, the greater the value of the Sharpe ratio, the more attractive the risk-adjusted return.'

Which means for our asset as example:
  • Looking at the Sharpe Ratio of 0.39 in the last 5 years of SPDR S&P 500, we see it is relatively greater, thus better in comparison to the benchmark SPY (0.39)
  • Compared with SPY (0.36) in the period of the last 3 years, the ratio of return and volatility (Sharpe) of 0.36 is larger, thus better.

Sortino:

'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.'

Using this definition on our asset we see for example:
  • Compared with the benchmark SPY (0.54) in the period of the last 5 years, the downside risk / excess return profile of 0.54 of SPDR S&P 500 is higher, thus better.
  • Compared with SPY (0.5) in the period of the last 3 years, the ratio of annual return and downside deviation of 0.5 is larger, thus better.

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:
  • The Downside risk index over 5 years of SPDR S&P 500 is 5.81 , which is larger, thus worse compared to the benchmark SPY (5.81 ) in the same period.
  • Compared with SPY (6.86 ) in the period of the last 3 years, the Downside risk index of 6.86 is larger, thus worse.

MaxDD:

'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 -33.7 days in the last 5 years of SPDR S&P 500, we see it is relatively higher, thus better in comparison to the benchmark SPY (-33.7 days)
  • During the last 3 years, the maximum reduction from previous high is -33.7 days, which is higher, thus better than the value of -33.7 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.'

Using this definition on our asset we see for example:
  • The maximum days below previous high over 5 years of SPDR S&P 500 is 187 days, which is greater, thus worse compared to the benchmark SPY (187 days) in the same period.
  • During the last 3 years, the maximum days below previous high is 139 days, which is larger, thus worse than the value of 139 days from the benchmark.

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:
  • The average days under water over 5 years of SPDR S&P 500 is 43 days, which is larger, thus worse compared to the benchmark SPY (43 days) in the same period.
  • During the last 3 years, the average days below previous high is 39 days, which is higher, thus worse than the value of 39 days from the benchmark.
