Gilead Sciences (GILD)

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 (65.8%) in the period of the last 5 years, the total return, or performance of -28.6% of Gilead Sciences is lower, thus worse.
• During the last 3 years, the total return, or increase in value is -7.7%, which is lower, thus worse than the value of 48.8% from the benchmark.

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.'

• Compared with the benchmark SPY (10.6%) in the period of the last 5 years, the compounded annual growth rate (CAGR) of -6.5% of Gilead Sciences is lower, thus worse.
• During the last 3 years, the annual return (CAGR) is -2.6%, which is lower, thus worse than the value of 14.2% 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.'

• The 30 days standard deviation over 5 years of Gilead Sciences is 26.6%, which is higher, thus worse compared to the benchmark SPY (13.6%) in the same period.
• During the last 3 years, the 30 days standard deviation is 23.6%, which is greater, thus worse than the value of 12.8% 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.'

• Compared with the benchmark SPY (15%) in the period of the last 5 years, the downside risk of 28.5% of Gilead Sciences is higher, thus worse.
• During the last 3 years, the downside deviation is 24.2%, which is greater, thus worse than the value of 14.6% 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.'

• The Sharpe Ratio over 5 years of Gilead Sciences is -0.34, which is lower, thus worse compared to the benchmark SPY (0.6) in the same period.
• Looking at ratio of return and volatility (Sharpe) in of -0.22 in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (0.91).

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.'

• Looking at the downside risk / excess return profile of -0.32 in the last 5 years of Gilead Sciences, we see it is relatively lower, thus worse in comparison to the benchmark SPY (0.54)
• Compared with SPY (0.8) in the period of the last 3 years, the ratio of annual return and downside deviation of -0.21 is lower, thus worse.

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.'

• The Downside risk index over 5 years of Gilead Sciences is 32 , which is greater, thus worse compared to the benchmark SPY (4.03 ) in the same period.
• During the last 3 years, the Ulcer Ratio is 17 , which is greater, thus worse than the value of 4.1 from the benchmark.

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.'

• Looking at the maximum DrawDown of -45.7 days in the last 5 years of Gilead Sciences, we see it is relatively lower, thus worse in comparison to the benchmark SPY (-19.3 days)
• Looking at maximum reduction from previous high in of -29.7 days in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (-19.3 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 days under water of 1066 days in the last 5 years of Gilead Sciences, we see it is relatively larger, thus worse in comparison to the benchmark SPY (187 days)
• During the last 3 years, the maximum time in days below previous high water mark is 411 days, which is larger, thus worse than the value of 139 days from the benchmark.

AveDuration:

'The Average 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. 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.'

• Compared with the benchmark SPY (41 days) in the period of the last 5 years, the average time in days below previous high water mark of 466 days of Gilead Sciences is higher, thus worse.
• Compared with SPY (35 days) in the period of the last 3 years, the average days under water of 158 days is higher, thus worse.
