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.'

• Looking at the total return, or increase in value of 188.1% in the last 5 years of Costco, we see it is relatively greater, thus better in comparison to the benchmark SPY (90.1%)
• Looking at total return, or performance in of 102.3% in the period of the last 3 years, we see it is relatively greater, thus better in comparison to SPY (76.5%).

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.'

• Compared with the benchmark SPY (13.8%) in the period of the last 5 years, the annual return (CAGR) of 23.7% of Costco is greater, thus better.
• Compared with SPY (21%) in the period of the last 3 years, the annual return (CAGR) of 26.7% is greater, thus better.

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 (17%) in the period of the last 5 years, the historical 30 days volatility of 22.6% of Costco is larger, thus worse.
• Compared with SPY (15.2%) in the period of the last 3 years, the volatility of 19.6% is larger, thus worse.

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.'

• The downside risk over 5 years of Costco is 15.9%, which is higher, thus worse compared to the benchmark SPY (11.7%) in the same period.
• Compared with SPY (10.2%) in the period of the last 3 years, the downside volatility of 13.5% is larger, thus worse.

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 Sharpe Ratio of 0.94 in the last 5 years of Costco, we see it is relatively greater, thus better in comparison to the benchmark SPY (0.66)
• Looking at ratio of return and volatility (Sharpe) in of 1.23 in the period of the last 3 years, we see it is relatively larger, thus better in comparison to SPY (1.22).

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.'

• The downside risk / excess return profile over 5 years of Costco is 1.33, which is higher, thus better compared to the benchmark SPY (0.96) in the same period.
• Looking at excess return divided by the downside deviation in of 1.79 in the period of the last 3 years, we see it is relatively smaller, thus worse in comparison to SPY (1.82).

Ulcer:

'The ulcer index is a stock market risk measure or technical analysis indicator devised by Peter Martin in 1987, and published by him and Byron McCann in their 1989 book The Investors Guide to Fidelity Funds. It's designed as a measure of volatility, but only volatility in the downward direction, i.e. the amount of drawdown or retracement occurring over a period. Other volatility measures like standard deviation treat up and down movement equally, but a trader doesn't mind upward movement, it's the downside that causes stress and stomach ulcers that the index's name suggests.'

• Looking at the Downside risk index of 11 in the last 5 years of Costco, we see it is relatively higher, thus worse in comparison to the benchmark SPY (8.42 )
• During the last 3 years, the Ulcer Ratio is 7.45 , which is greater, thus worse than the value of 3.48 from the benchmark.

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.'

• Looking at the maximum drop from peak to valley of -31.4 days in the last 5 years of Costco, we see it is relatively smaller, thus worse in comparison to the benchmark SPY (-24.5 days)
• During the last 3 years, the maximum reduction from previous high is -20.7 days, which is smaller, thus worse than the value of -18.8 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.'

• The maximum days under water over 5 years of Costco is 416 days, which is lower, thus better compared to the benchmark SPY (488 days) in the same period.
• During the last 3 years, the maximum days under water is 248 days, which is higher, 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 under water of 112 days in the last 5 years of Costco, we see it is relatively lower, thus better in comparison to the benchmark SPY (119 days)
• Looking at average days under water in of 57 days in the period of the last 3 years, we see it is relatively larger, thus worse in comparison to SPY (19 days).
