Statistics of iShares Global Tech ETF (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:
  • The total return over 5 years of iShares Global Tech ETF is 123.3%, which is larger, thus better compared to the benchmark SPY (66.9%) in the same period.
  • During the last 3 years, the total return is 89.7%, which is greater, thus better than the value of 50.6% 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.'

Using this definition on our asset we see for example:
  • Compared with the benchmark SPY (10.8%) in the period of the last 5 years, the compounded annual growth rate (CAGR) of 17.5% of iShares Global Tech ETF is greater, thus better.
  • Looking at annual return (CAGR) in of 23.9% in the period of the last 3 years, we see it is relatively greater, thus better in comparison to SPY (14.7%).

Volatility:

'Volatility is a statistical measure of the dispersion of returns for a given security or market index. Volatility can either be measured by using the standard deviation or variance between returns from that same security or market index. Commonly, the higher the volatility, the riskier the security. In the securities markets, volatility is often associated with big swings in either direction. For example, when the stock market rises and falls more than one percent over a sustained period of time, it is called a 'volatile' market.'

Which means for our asset as example:
  • Compared with the benchmark SPY (13.5%) in the period of the last 5 years, the historical 30 days volatility of 17.6% of iShares Global Tech ETF is greater, thus worse.
  • Looking at 30 days standard deviation in of 18.2% in the period of the last 3 years, we see it is relatively higher, thus worse in comparison to SPY (12.8%).

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:
  • Looking at the downside risk of 20.1% in the last 5 years of iShares Global Tech ETF, we see it is relatively higher, thus worse in comparison to the benchmark SPY (14.8%)
  • Looking at downside volatility in of 21.4% in the period of the last 3 years, we see it is relatively higher, thus worse in comparison to SPY (14.7%).

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 iShares Global Tech ETF is 0.85, which is larger, thus better compared to the benchmark SPY (0.61) in the same period.
  • Compared with SPY (0.95) in the period of the last 3 years, the ratio of return and volatility (Sharpe) of 1.18 is higher, thus better.

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 iShares Global Tech ETF is 0.74, which is larger, thus better compared to the benchmark SPY (0.56) in the same period.
  • Compared with SPY (0.83) in the period of the last 3 years, the ratio of annual return and downside deviation of 1 is larger, 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.'

Using this definition on our asset we see for example:
  • Looking at the Ulcer Index of 5.25 in the last 5 years of iShares Global Tech ETF, we see it is relatively larger, thus worse in comparison to the benchmark SPY (3.99 )
  • Looking at Ulcer Index in of 5.47 in the period of the last 3 years, we see it is relatively greater, thus worse in comparison to SPY (4.1 ).

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:
  • Compared with the benchmark SPY (-19.3 days) in the period of the last 5 years, the maximum drop from peak to valley of -23.6 days of iShares Global Tech ETF is smaller, thus worse.
  • During the last 3 years, the maximum reduction from previous high is -23.6 days, which is smaller, thus worse than the value of -19.3 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.'

Which means for our asset as example:
  • Compared with the benchmark SPY (187 days) in the period of the last 5 years, the maximum days below previous high of 154 days of iShares Global Tech ETF is smaller, thus better.
  • Compared with SPY (139 days) in the period of the last 3 years, the maximum days under water of 154 days is larger, 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.'

Using this definition on our asset we see for example:
  • The average days under water over 5 years of iShares Global Tech ETF is 36 days, which is lower, thus better compared to the benchmark SPY (42 days) in the same period.
  • During the last 3 years, the average days under water is 31 days, which is lower, thus better than the value of 36 days from the benchmark.
