SanDisk (SNDK)

TotalReturn:

'The total return on a portfolio of investments takes into account not only the capital appreciation on the portfolio, but also the income received on the portfolio. The income typically consists of interest, dividends, and securities lending fees. This contrasts with the price return, which takes into account only the capital gain on an investment.'

• Looking at the total return of 60.5% in the last 5 years of SanDisk, we see it is relatively smaller, thus worse in comparison to the benchmark SPY (81.9%)
• During the last 3 years, the total return, or performance is 33.1%, which is lower, thus worse than the value of 46.1% 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.'

• Looking at the compounded annual growth rate (CAGR) of 9.9% in the last 5 years of SanDisk, we see it is relatively smaller, thus worse in comparison to the benchmark SPY (12.7%)
• During the last 3 years, the annual return (CAGR) is 10%, which is lower, thus worse than the value of 13.5% 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.'

• Looking at the historical 30 days volatility of 36.9% in the last 5 years of SanDisk, we see it is relatively larger, thus worse in comparison to the benchmark SPY (19.8%)
• Compared with SPY (23%) in the period of the last 3 years, the volatility of 35% is greater, thus worse.

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 (14.5%) in the period of the last 5 years, the downside deviation of 25.8% of SanDisk is larger, thus worse.
• Looking at downside deviation in of 24.4% in the period of the last 3 years, we see it is relatively greater, thus worse in comparison to SPY (16.8%).

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.'

• Compared with the benchmark SPY (0.52) in the period of the last 5 years, the ratio of return and volatility (Sharpe) of 0.2 of SanDisk is lower, thus worse.
• Looking at ratio of return and volatility (Sharpe) in of 0.21 in the period of the last 3 years, we see it is relatively smaller, thus worse in comparison to SPY (0.48).

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.'

• Compared with the benchmark SPY (0.7) in the period of the last 5 years, the excess return divided by the downside deviation of 0.29 of SanDisk is lower, thus worse.
• Compared with SPY (0.65) in the period of the last 3 years, the excess return divided by the downside deviation of 0.31 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 SanDisk is 22 , which is higher, thus worse compared to the benchmark SPY (6.08 ) in the same period.
• Compared with SPY (6.77 ) in the period of the last 3 years, the Ulcer Ratio of 25 is greater, 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.'

• Looking at the maximum drop from peak to valley of -57.2 days in the last 5 years of SanDisk, we see it is relatively lower, thus worse in comparison to the benchmark SPY (-33.7 days)
• Compared with SPY (-33.7 days) in the period of the last 3 years, the maximum DrawDown of -57.2 days is smaller, thus worse.

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.'

• Compared with the benchmark SPY (139 days) in the period of the last 5 years, the maximum days under water of 459 days of SanDisk is larger, thus worse.
• Looking at maximum time in days below previous high water mark in of 459 days in the period of the last 3 years, we see it is relatively higher, thus worse in comparison to SPY (119 days).

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.'

• Compared with the benchmark SPY (35 days) in the period of the last 5 years, the average days under water of 146 days of SanDisk is greater, thus worse.
• Looking at average time in days below previous high water mark in of 157 days in the period of the last 3 years, we see it is relatively larger, thus worse in comparison to SPY (27 days).
