Statistics (YTD)

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

TotalReturn:

'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.'

Using this definition on our asset we see for example:
  • Compared with the benchmark SPY (121.2%) in the period of the last 5 years, the total return, or performance of 36% of Express Scripts is smaller, thus worse.
  • Compared with SPY (67.5%) in the period of the last 3 years, the total return of 7.8% is smaller, thus worse.

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:
  • Compared with the benchmark SPY (17.2%) in the period of the last 5 years, the annual performance (CAGR) of 6.3% of Express Scripts is smaller, thus worse.
  • During the last 3 years, the annual return (CAGR) is 2.5%, which is lower, thus worse than the value of 18.7% 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.'

Which means for our asset as example:
  • Looking at the historical 30 days volatility of 22.9% in the last 5 years of Express Scripts, we see it is relatively larger, thus worse in comparison to the benchmark SPY (18.7%)
  • Looking at historical 30 days volatility in of 24.8% in the period of the last 3 years, we see it is relatively higher, thus worse in comparison to SPY (22.5%).

DownVol:

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

Applying this definition to our asset in some examples:
  • The downside deviation over 5 years of Express Scripts is 16.4%, which is greater, thus worse compared to the benchmark SPY (13.6%) in the same period.
  • Compared with SPY (16.3%) in the period of the last 3 years, the downside deviation of 17.9% 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.'

Using this definition on our asset we see for example:
  • Compared with the benchmark SPY (0.79) in the period of the last 5 years, the risk / return profile (Sharpe) of 0.17 of Express Scripts is lower, thus worse.
  • Compared with SPY (0.72) in the period of the last 3 years, the Sharpe Ratio of 0 is lower, thus worse.

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.'

Applying this definition to our asset in some examples:
  • Compared with the benchmark SPY (1.08) in the period of the last 5 years, the downside risk / excess return profile of 0.23 of Express Scripts is smaller, thus worse.
  • During the last 3 years, the ratio of annual return and downside deviation is 0, which is lower, thus worse than the value of 1 from the benchmark.

Ulcer:

'Ulcer Index is a method for measuring investment risk that addresses the real concerns of investors, unlike the widely used standard deviation of return. UI is a measure of the depth and duration of drawdowns in prices from earlier highs. Using Ulcer Index instead of standard deviation can lead to very different conclusions about investment risk and risk-adjusted return, especially when evaluating strategies that seek to avoid major declines in portfolio value (market timing, dynamic asset allocation, hedge funds, etc.). The Ulcer Index was originally developed in 1987. Since then, it has been widely recognized and adopted by the investment community. According to Nelson Freeburg, editor of Formula Research, Ulcer Index is “perhaps the most fully realized statistical portrait of risk there is.'

Applying this definition to our asset in some examples:
  • Looking at the Ulcer Index of 19 in the last 5 years of Express Scripts, we see it is relatively greater, thus worse in comparison to the benchmark SPY (5.59 )
  • Looking at Ulcer Ratio in of 20 in the period of the last 3 years, we see it is relatively larger, thus worse in comparison to SPY (6.83 ).

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 reduction from previous high over 5 years of Express Scripts is -39.6 days, which is lower, thus worse compared to the benchmark SPY (-33.7 days) in the same period.
  • Looking at maximum reduction from previous high in of -35.6 days in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (-33.7 days).

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:
  • Compared with the benchmark SPY (139 days) in the period of the last 5 years, the maximum time in days below previous high water mark of 794 days of Express Scripts is higher, thus worse.
  • During the last 3 years, the maximum days below previous high is 673 days, which is greater, 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.'

Applying this definition to our asset in some examples:
  • The average days under water over 5 years of Express Scripts is 279 days, which is larger, thus worse compared to the benchmark SPY (33 days) in the same period.
  • Compared with SPY (35 days) in the period of the last 3 years, the average days below previous high of 310 days is larger, thus worse.
