Statistics of Seagate Technology (YTD)

What do these metrics mean? [Read More] [Hide]

TotalReturn:

'Total return, when measuring performance, is the actual rate of return of an investment or a pool of investments over a given evaluation period. Total return includes interest, capital gains, dividends and distributions realized over a given period of time. Total return accounts for two categories of return: income including interest paid by fixed-income investments, distributions or dividends and capital appreciation, representing the change in the market price of an asset.'

Applying this definition to our asset in some examples:
  • Compared with the benchmark SPY (64.1%) in the period of the last 5 years, the total return, or performance of 19% of Seagate Technology is lower, thus worse.
  • Looking at total return, or increase in value in of 70.7% in the period of the last 3 years, we see it is relatively greater, thus better in comparison to SPY (48.1%).

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.'

Which means for our asset as example:
  • Compared with the benchmark SPY (10.4%) in the period of the last 5 years, the annual return (CAGR) of 3.5% of Seagate Technology is lower, thus worse.
  • Looking at annual performance (CAGR) in of 19.5% in the period of the last 3 years, we see it is relatively greater, thus better in comparison to SPY (14%).

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.'

Which means for our asset as example:
  • The historical 30 days volatility over 5 years of Seagate Technology is 40.8%, which is larger, thus worse compared to the benchmark SPY (13.6%) in the same period.
  • Compared with SPY (12.8%) in the period of the last 3 years, the 30 days standard deviation of 36.6% is higher, thus worse.

DownVol:

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

Using this definition on our asset we see for example:
  • The downside deviation over 5 years of Seagate Technology is 45.4%, which is larger, thus worse compared to the benchmark SPY (14.9%) in the same period.
  • Compared with SPY (14.5%) in the period of the last 3 years, the downside volatility of 41.3% is larger, thus worse.

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.'

Which means for our asset as example:
  • The ratio of return and volatility (Sharpe) over 5 years of Seagate Technology is 0.03, which is smaller, thus worse compared to the benchmark SPY (0.58) in the same period.
  • During the last 3 years, the ratio of return and volatility (Sharpe) is 0.46, which is lower, thus worse than the value of 0.9 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.'

Using this definition on our asset we see for example:
  • The excess return divided by the downside deviation over 5 years of Seagate Technology is 0.02, which is lower, thus worse compared to the benchmark SPY (0.53) in the same period.
  • Looking at ratio of annual return and downside deviation in of 0.41 in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (0.79).

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.'

Which means for our asset as example:
  • Compared with the benchmark SPY (4.02 ) in the period of the last 5 years, the Downside risk index of 32 of Seagate Technology is higher, thus worse.
  • During the last 3 years, the Downside risk index is 19 , which is higher, thus worse than the value of 4.09 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.'

Which means for our asset as example:
  • The maximum DrawDown over 5 years of Seagate Technology is -70.1 days, which is lower, thus worse compared to the benchmark SPY (-19.3 days) in the same period.
  • Compared with SPY (-19.3 days) in the period of the last 3 years, the maximum reduction from previous high of -39.4 days is lower, 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.'

Applying this definition to our asset in some examples:
  • The maximum days under water over 5 years of Seagate Technology is 804 days, which is greater, thus worse compared to the benchmark SPY (187 days) in the same period.
  • During the last 3 years, the maximum time in days below previous high water mark is 359 days, which is higher, thus worse than the value of 139 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.'

Which means for our asset as example:
  • Looking at the average days under water of 315 days in the last 5 years of Seagate Technology, we see it is relatively greater, thus worse in comparison to the benchmark SPY (41 days)
  • During the last 3 years, the average days below previous high is 117 days, which is larger, thus worse than the value of 35 days from the benchmark.
