Costco (COST)

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 (81.9%) in the period of the last 5 years, the total return, or performance of 210.6% of Costco is greater, thus better.
• Compared with SPY (46.1%) in the period of the last 3 years, the total return, or increase in value of 110% is greater, thus better.

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 25.5% in the last 5 years of Costco, we see it is relatively larger, thus better in comparison to the benchmark SPY (12.7%)
• Looking at annual performance (CAGR) in of 28.1% in the period of the last 3 years, we see it is relatively greater, thus better in comparison to SPY (13.5%).

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 (19.8%) in the period of the last 5 years, the historical 30 days volatility of 22.5% of Costco is larger, thus worse.
• During the last 3 years, the 30 days standard deviation is 23.4%, which is larger, thus worse than the value of 23% 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 risk over 5 years of Costco is 15.4%, which is greater, thus worse compared to the benchmark SPY (14.5%) in the same period.
• During the last 3 years, the downside volatility is 15.3%, which is lower, thus better than the value of 16.8% from the benchmark.

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.'

• Compared with the benchmark SPY (0.52) in the period of the last 5 years, the risk / return profile (Sharpe) of 1.02 of Costco is greater, thus better.
• During the last 3 years, the ratio of return and volatility (Sharpe) is 1.09, which is greater, thus better than the value of 0.48 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 (0.7) in the period of the last 5 years, the excess return divided by the downside deviation of 1.49 of Costco is greater, thus better.
• Compared with SPY (0.65) in the period of the last 3 years, the excess return divided by the downside deviation of 1.67 is greater, thus better.

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 Ulcer Ratio over 5 years of Costco is 6.73 , which is larger, thus worse compared to the benchmark SPY (6.08 ) in the same period.
• During the last 3 years, the Downside risk index is 5.59 , which is lower, thus better than the value of 6.77 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 -22 days in the last 5 years of Costco, we see it is relatively greater, thus better in comparison to the benchmark SPY (-33.7 days)
• During the last 3 years, the maximum reduction from previous high is -19.9 days, which is larger, thus better than the value of -33.7 days from the benchmark.

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 137 days in the last 5 years of Costco, we see it is relatively smaller, thus better in comparison to the benchmark SPY (139 days)
• During the last 3 years, the maximum days under water is 121 days, which is larger, thus worse than the value of 119 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.'

• Looking at the average time in days below previous high water mark of 36 days in the last 5 years of Costco, we see it is relatively higher, thus worse in comparison to the benchmark SPY (35 days)
• Looking at average days under water in of 28 days in the period of the last 3 years, we see it is relatively higher, thus worse in comparison to SPY (27 days).
