Express Scripts (ESRX)

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.'

• Compared with the benchmark SPY (109.3%) in the period of the last 5 years, the total return, or performance of 33.9% of Express Scripts is smaller, thus worse.
• Looking at total return in of 7.8% in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (34.3%).

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.'

• 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 (16%)
• During the last 3 years, the annual return (CAGR) is 2.5%, which is smaller, thus worse than the value of 10.4% from the benchmark.

Volatility:

'In finance, volatility (symbol σ) is the degree of variation of a trading price series over time as measured by the standard deviation of logarithmic returns. Historic volatility measures a time series of past market prices. Implied volatility looks forward in time, being derived from the market price of a market-traded derivative (in particular, an option). Commonly, the higher the volatility, the riskier the security.'

• Compared with the benchmark SPY (18%) in the period of the last 5 years, the historical 30 days volatility of 22.9% of Express Scripts is greater, thus worse.
• During the last 3 years, the volatility is 24.8%, which is higher, thus worse than the value of 18.8% from the benchmark.

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.'

• Looking at the downside risk of 16.4% in the last 5 years of Express Scripts, we see it is relatively higher, thus worse in comparison to the benchmark SPY (12.5%)
• Looking at downside risk in of 17.9% in the period of the last 3 years, we see it is relatively larger, thus worse in comparison to SPY (13%).

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.'

• Compared with the benchmark SPY (0.75) in the period of the last 5 years, the Sharpe Ratio of 0.15 of Express Scripts is lower, thus worse.
• Looking at ratio of return and volatility (Sharpe) in of 0 in the period of the last 3 years, we see it is relatively smaller, thus worse in comparison to SPY (0.42).

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.'

• The downside risk / excess return profile over 5 years of Express Scripts is 0.21, which is smaller, thus worse compared to the benchmark SPY (1.07) in the same period.
• Compared with SPY (0.6) in the period of the last 3 years, the excess return divided by the downside deviation of 0 is lower, 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.'

• Looking at the Downside risk 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 (8.45 )
• During the last 3 years, the Ulcer Index is 20 , which is larger, thus worse than the value of 5.75 from the benchmark.

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.'

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

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). Many assume Max DD Duration is the length of time between new highs during which the Max DD (magnitude) occurred. But that isn’t always the case. The Max DD duration is the longest time between peaks, period. So it could be the time when the program also had its biggest peak to valley loss (and usually is, because the program needs a long time to recover from the largest loss), but it doesn’t have to be'

• The maximum time in days below previous high water mark over 5 years of Express Scripts is 794 days, which is higher, thus worse compared to the benchmark SPY (488 days) in the same period.
• During the last 3 years, the maximum days below previous high is 673 days, which is greater, thus worse than the value of 199 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 larger, thus worse in comparison to the benchmark SPY (118 days)
• During the last 3 years, the average time in days below previous high water mark is 310 days, which is greater, thus worse than the value of 45 days from the benchmark.
