Statistics of iShares Global Healthcare 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.'

Which means for our asset as example:
  • Compared with the benchmark SPY (66.7%) in the period of the last 5 years, the total return, or performance of 42.3% of iShares Global Healthcare ETF is lower, thus worse.
  • Compared with SPY (46%) in the period of the last 3 years, the total return of 23.6% is lower, thus worse.

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.'

Using this definition on our asset we see for example:
  • Looking at the compounded annual growth rate (CAGR) of 7.3% in the last 5 years of iShares Global Healthcare ETF, we see it is relatively lower, thus worse in comparison to the benchmark SPY (10.8%)
  • Compared with SPY (13.5%) in the period of the last 3 years, the compounded annual growth rate (CAGR) of 7.3% is smaller, thus worse.

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.'

Applying this definition to our asset in some examples:
  • Looking at the 30 days standard deviation of 13.9% in the last 5 years of iShares Global Healthcare ETF, we see it is relatively higher, thus worse in comparison to the benchmark SPY (13.4%)
  • During the last 3 years, the 30 days standard deviation is 12.5%, which is higher, thus worse than the value of 12.3% from the benchmark.

DownVol:

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

Which means for our asset as example:
  • Looking at the downside volatility of 15% in the last 5 years of iShares Global Healthcare ETF, we see it is relatively larger, thus worse in comparison to the benchmark SPY (14.6%)
  • During the last 3 years, the downside deviation is 13.9%, which is larger, thus worse than the value of 13.9% from the benchmark.

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.'

Applying this definition to our asset in some examples:
  • Compared with the benchmark SPY (0.62) in the period of the last 5 years, the Sharpe Ratio of 0.35 of iShares Global Healthcare ETF is lower, thus worse.
  • Compared with SPY (0.89) in the period of the last 3 years, the Sharpe Ratio of 0.39 is lower, thus worse.

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.'

Applying this definition to our asset in some examples:
  • Compared with the benchmark SPY (0.57) in the period of the last 5 years, the excess return divided by the downside deviation of 0.32 of iShares Global Healthcare ETF is lower, thus worse.
  • Looking at ratio of annual return and downside deviation in of 0.35 in the period of the last 3 years, we see it is relatively smaller, thus worse in comparison to SPY (0.79).

Ulcer:

'The Ulcer Index is a technical indicator that measures downside risk, in terms of both the depth and duration of price declines. The index increases in value as the price moves farther away from a recent high and falls as the price rises to new highs. The indicator is usually calculated over a 14-day period, with the Ulcer Index showing the percentage drawdown a trader can expect from the high over that period. The greater the value of the Ulcer Index, the longer it takes for a stock to get back to the former high.'

Which means for our asset as example:
  • The Downside risk index over 5 years of iShares Global Healthcare ETF is 7.09 , which is higher, thus worse compared to the benchmark SPY (3.99 ) in the same period.
  • Compared with SPY (4.04 ) in the period of the last 3 years, the Ulcer Index of 5.38 is larger, 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.'

Using this definition on our asset we see for example:
  • The maximum reduction from previous high over 5 years of iShares Global Healthcare ETF is -18.8 days, which is larger, thus better 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 DrawDown of -14.4 days is greater, thus better.

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.'

Applying this definition to our asset in some examples:
  • Compared with the benchmark SPY (187 days) in the period of the last 5 years, the maximum time in days below previous high water mark of 470 days of iShares Global Healthcare ETF is greater, thus worse.
  • During the last 3 years, the maximum days below previous high is 188 days, which is larger, 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:
  • The average days below previous high over 5 years of iShares Global Healthcare ETF is 123 days, which is larger, thus worse compared to the benchmark SPY (41 days) in the same period.
  • During the last 3 years, the average time in days below previous high water mark is 69 days, which is higher, thus worse than the value of 36 days from the benchmark.
