Vanguard Intermediate Term Treasury Fund Investor Shares

'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.'

Applying this definition to our asset in some examples:- Looking at the total return of 16.3% in the last 5 years of Vanguard Intermediate Term Treasury Fund, we see it is relatively lower, thus worse in comparison to the benchmark SPY (46.1%)
- Compared with SPY (23.5%) in the period of the last 3 years, the total return, or performance of 14.6% is lower, thus worse.

'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:- The annual performance (CAGR) over 5 years of Vanguard Intermediate Term Treasury Fund is 3.1%, which is smaller, thus worse compared to the benchmark SPY (7.9%) in the same period.
- Looking at compounded annual growth rate (CAGR) in of 4.7% in the period of the last 3 years, we see it is relatively lower, thus worse in comparison to SPY (7.3%).

'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.'

Applying this definition to our asset in some examples:- Looking at the historical 30 days volatility of 3.7% in the last 5 years of Vanguard Intermediate Term Treasury Fund, we see it is relatively lower, thus better in comparison to the benchmark SPY (18.3%)
- During the last 3 years, the 30 days standard deviation is 3.7%, which is smaller, thus better than the value of 20.8% from the benchmark.

'Downside risk is the financial risk associated with losses. That is, it is the risk of the actual return being below the expected return, or the uncertainty about the magnitude of that difference. Risk measures typically quantify the downside risk, whereas the standard deviation (an example of a deviation risk measure) measures both the upside and downside risk. Specifically, downside risk in our definition is the semi-deviation, that is the standard deviation of all negative returns.'

Using this definition on our asset we see for example:- Looking at the downside risk of 2.5% in the last 5 years of Vanguard Intermediate Term Treasury Fund, we see it is relatively smaller, thus better in comparison to the benchmark SPY (13.4%)
- Compared with SPY (15.4%) in the period of the last 3 years, the downside deviation of 2.3% is smaller, thus better.

'The Sharpe ratio (also known as the Sharpe index, the Sharpe measure, and the reward-to-variability ratio) is a way to examine the performance of an investment by adjusting for its risk. The ratio measures the excess return (or risk premium) per unit of deviation in an investment asset or a trading strategy, typically referred to as risk, named after William F. Sharpe.'

Which means for our asset as example:- Compared with the benchmark SPY (0.29) in the period of the last 5 years, the risk / return profile (Sharpe) of 0.15 of Vanguard Intermediate Term Treasury Fund is lower, thus worse.
- Looking at risk / return profile (Sharpe) in of 0.59 in the period of the last 3 years, we see it is relatively higher, thus better in comparison to SPY (0.23).

'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.'

Which means for our asset as example:- Looking at the excess return divided by the downside deviation of 0.23 in the last 5 years of Vanguard Intermediate Term Treasury Fund, we see it is relatively smaller, thus worse in comparison to the benchmark SPY (0.4)
- Compared with SPY (0.31) in the period of the last 3 years, the ratio of annual return and downside deviation of 0.92 is larger, thus better.

'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:- Looking at the Ulcer Ratio of 2.56 in the last 5 years of Vanguard Intermediate Term Treasury Fund, we see it is relatively lower, thus better in comparison to the benchmark SPY (5.27 )
- During the last 3 years, the Downside risk index is 2.12 , which is lower, thus better than the value of 6.08 from the benchmark.

'Maximum drawdown measures the loss in any losing period during a fund’s investment record. It is defined as the percent retrenchment from a fund’s peak value to the fund’s valley value. The drawdown is in effect from the time the fund’s retrenchment begins until a new fund high is reached. The maximum drawdown encompasses both the period from the fund’s peak to the fund’s valley (length), and the time from the fund’s valley to a new fund high (recovery). It measures the largest percentage drawdown that has occurred in any fund’s data record.'

Using this definition on our asset we see for example:- Looking at the maximum reduction from previous high of -5.5 days in the last 5 years of Vanguard Intermediate Term Treasury Fund, we see it is relatively higher, thus better in comparison to the benchmark SPY (-33.7 days)
- During the last 3 years, the maximum DrawDown is -4.7 days, which is greater, thus better than the value of -33.7 days from the benchmark.

'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.'

Which means for our asset as example:- Looking at the maximum days under water of 681 days in the last 5 years of Vanguard Intermediate Term Treasury Fund, we see it is relatively higher, thus worse in comparison to the benchmark SPY (187 days)
- Looking at maximum days below previous high in of 377 days in the period of the last 3 years, we see it is relatively higher, thus worse in comparison to SPY (139 days).

'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:- Compared with the benchmark SPY (42 days) in the period of the last 5 years, the average time in days below previous high water mark of 209 days of Vanguard Intermediate Term Treasury Fund is higher, thus worse.
- During the last 3 years, the average time in days below previous high water mark is 114 days, which is larger, thus worse than the value of 36 days from the benchmark.
