Western Digital (WDC)

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 performance of 20.2% in the last 5 years of Western Digital, we see it is relatively lower, thus worse in comparison to the benchmark SPY (94.2%)
• During the last 3 years, the total return is 4.3%, which is lower, thus worse than the value of 27.9% from the benchmark.

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 compounded annual growth rate (CAGR) of 3.8% in the last 5 years of Western Digital, we see it is relatively lower, thus worse in comparison to the benchmark SPY (14.2%)
• Looking at compounded annual growth rate (CAGR) in of 1.4% in the period of the last 3 years, we see it is relatively smaller, thus worse in comparison to SPY (8.6%).

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.'

• Compared with the benchmark SPY (20.9%) in the period of the last 5 years, the 30 days standard deviation of 48.8% of Western Digital is greater, thus worse.
• Looking at historical 30 days volatility in of 41.6% in the period of the last 3 years, we see it is relatively larger, thus worse in comparison to SPY (17.3%).

DownVol:

'The downside volatility is similar to the volatility, or standard deviation, but only takes losing/negative periods into account.'

• Compared with the benchmark SPY (15%) in the period of the last 5 years, the downside risk of 34.4% of Western Digital is higher, thus worse.
• Looking at downside deviation in of 28% in the period of the last 3 years, we see it is relatively greater, thus worse in comparison to SPY (12.1%).

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.'

• The ratio of return and volatility (Sharpe) over 5 years of Western Digital is 0.03, which is lower, thus worse compared to the benchmark SPY (0.56) in the same period.
• During the last 3 years, the risk / return profile (Sharpe) is -0.03, which is lower, thus worse than the value of 0.35 from the benchmark.

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 ratio of annual return and downside deviation over 5 years of Western Digital is 0.04, which is smaller, thus worse compared to the benchmark SPY (0.78) in the same period.
• Looking at downside risk / excess return profile in of -0.04 in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (0.5).

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.'

• The Downside risk index over 5 years of Western Digital is 34 , which is greater, thus worse compared to the benchmark SPY (9.32 ) in the same period.
• Compared with SPY (10 ) in the period of the last 3 years, the Ulcer Ratio of 32 is higher, thus worse.

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.'

• The maximum reduction from previous high over 5 years of Western Digital is -60.9 days, which is smaller, thus worse compared to the benchmark SPY (-33.7 days) in the same period.
• During the last 3 years, the maximum DrawDown is -56.1 days, which is smaller, thus worse than the value of -24.5 days from the benchmark.

MaxDuration:

'The Maximum 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. It is the length of time the account was in the Max Drawdown. A Max Drawdown measures a retrenchment from when an equity curve reaches a new high. It’s the maximum an account lost during that retrenchment. This method is applied because a valley can’t be measured until a new high occurs. Once the new high is reached, the percentage change from the old high to the bottom of the largest trough is recorded.'

• Looking at the maximum days below previous high of 749 days in the last 5 years of Western Digital, we see it is relatively higher, thus worse in comparison to the benchmark SPY (488 days)
• Compared with SPY (488 days) in the period of the last 3 years, the maximum time in days below previous high water mark of 664 days is higher, thus worse.

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 262 days in the last 5 years of Western Digital, we see it is relatively higher, thus worse in comparison to the benchmark SPY (123 days)
• Looking at average time in days below previous high water mark in of 300 days in the period of the last 3 years, we see it is relatively higher, thus worse in comparison to SPY (180 days).
