Express Scripts (ESRX)

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.'

• Looking at the total return, or performance of 33.9% in the last 5 years of Express Scripts, we see it is relatively lower, thus worse in comparison to the benchmark SPY (99.7%)
• Looking at total return, or performance in of 7.8% in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (74.8%).

CAGR:

'The compound annual growth rate (CAGR) is a useful measure of growth over multiple time periods. It can be thought of as the growth rate that gets you from the initial investment value to the ending investment value if you assume that the investment has been compounding over the time period.'

• Looking at the annual return (CAGR) of 6% in the last 5 years of Express Scripts, we see it is relatively lower, thus worse in comparison to the benchmark SPY (14.9%)
• Looking at annual return (CAGR) in of 2.5% in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (20.6%).

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.'

• Looking at the volatility of 22.9% in the last 5 years of Express Scripts, we see it is relatively higher, thus worse in comparison to the benchmark SPY (17.1%)
• During the last 3 years, the historical 30 days volatility is 24.8%, which is larger, thus worse than the value of 15.7% from the benchmark.

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.'

• The downside deviation over 5 years of Express Scripts is 16.4%, which is greater, thus worse compared to the benchmark SPY (11.8%) in the same period.
• During the last 3 years, the downside risk is 17.9%, which is greater, thus worse than the value of 10.5% from the benchmark.

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.'

• Looking at the ratio of return and volatility (Sharpe) of 0.15 in the last 5 years of Express Scripts, we see it is relatively lower, thus worse in comparison to the benchmark SPY (0.72)
• During the last 3 years, the risk / return profile (Sharpe) is 0, which is lower, thus worse than the value of 1.15 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.'

• Compared with the benchmark SPY (1.05) in the period of the last 5 years, the excess return divided by the downside deviation of 0.21 of Express Scripts is smaller, thus worse.
• Compared with SPY (1.73) in the period of the last 3 years, the excess return divided by the downside deviation of 0 is smaller, thus worse.

Ulcer:

'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.'

• Compared with the benchmark SPY (8.42 ) in the period of the last 5 years, the Ulcer Ratio of 19 of Express Scripts is greater, thus worse.
• Looking at Downside risk index in of 20 in the period of the last 3 years, we see it is relatively higher, thus worse in comparison to SPY (3.63 ).

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.'

• Compared with the benchmark SPY (-24.5 days) in the period of the last 5 years, the maximum reduction from previous high of -39.6 days of Express Scripts is smaller, thus worse.
• Looking at maximum drop from peak to valley in of -35.6 days in the period of the last 3 years, we see it is relatively smaller, thus worse in comparison to SPY (-18.8 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.'

• Looking at the maximum time in days below previous high water mark of 794 days in the last 5 years of Express Scripts, we see it is relatively greater, thus worse in comparison to the benchmark SPY (488 days)
• During the last 3 years, the maximum days under water is 673 days, which is larger, thus worse than the value of 87 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.'

• Looking at the average days below previous high of 279 days in the last 5 years of Express Scripts, we see it is relatively higher, thus worse in comparison to the benchmark SPY (120 days)
• Compared with SPY (21 days) in the period of the last 3 years, the average days below previous high of 310 days is larger, thus worse.
