'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.'

Using this definition on our asset we see for example:- Compared with the benchmark SPY (72.5%) in the period of the last 5 years, the total return of 18.3% of Vanguard Intermediate Term Treasury Fund is lower, thus worse.
- During the last 3 years, the total return, or increase in value is 15.6%, which is lower, thus worse than the value of 34.1% from the benchmark.

'Compound annual growth rate (CAGR) is a business and investing specific term for the geometric progression ratio that provides a constant rate of return over the time period. CAGR is not an accounting term, but it is often used to describe some element of the business, for example revenue, units delivered, registered users, etc. CAGR dampens the effect of volatility of periodic returns that can render arithmetic means irrelevant. It is particularly useful to compare growth rates from various data sets of common domain such as revenue growth of companies in the same industry.'

Applying this definition to our asset in some examples:- Compared with the benchmark SPY (11.5%) in the period of the last 5 years, the annual return (CAGR) of 3.4% of Vanguard Intermediate Term Treasury Fund is lower, thus worse.
- During the last 3 years, the annual return (CAGR) is 4.9%, which is lower, thus worse than the value of 10.3% from the benchmark.

'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.'

Using this definition on our asset we see for example:- Compared with the benchmark SPY (18.9%) in the period of the last 5 years, the 30 days standard deviation of 3.5% of Vanguard Intermediate Term Treasury Fund is lower, thus better.
- Compared with SPY (22.6%) in the period of the last 3 years, the volatility of 3.6% is lower, thus better.

'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:- Compared with the benchmark SPY (13.8%) in the period of the last 5 years, the downside deviation of 2.3% of Vanguard Intermediate Term Treasury Fund is smaller, thus better.
- Looking at downside volatility in of 2.3% in the period of the last 3 years, we see it is relatively lower, thus better in comparison to SPY (16.7%).

'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.'

Using this definition on our asset we see for example:- Compared with the benchmark SPY (0.48) in the period of the last 5 years, the Sharpe Ratio of 0.26 of Vanguard Intermediate Term Treasury Fund is lower, thus worse.
- Compared with SPY (0.34) in the period of the last 3 years, the Sharpe Ratio of 0.68 is greater, thus better.

'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.'

Applying this definition to our asset in some examples:- Compared with the benchmark SPY (0.65) in the period of the last 5 years, the ratio of annual return and downside deviation of 0.4 of Vanguard Intermediate Term Treasury Fund is lower, thus worse.
- Compared with SPY (0.47) in the period of the last 3 years, the excess return divided by the downside deviation of 1.07 is greater, 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 2.51 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 (5.83 )
- Compared with SPY (7.13 ) in the period of the last 3 years, the Ulcer Ratio of 1.4 is lower, thus better.

'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.'

Which means for our asset as example:- Compared with the benchmark SPY (-33.7 days) in the period of the last 5 years, the maximum drop from peak to valley of -5.5 days of Vanguard Intermediate Term Treasury Fund is larger, thus better.
- During the last 3 years, the maximum reduction from previous high is -3.4 days, which is higher, 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:- Compared with the benchmark SPY (139 days) in the period of the last 5 years, the maximum days under water of 681 days of Vanguard Intermediate Term Treasury Fund is higher, thus worse.
- Looking at maximum time in days below previous high water mark in of 285 days in the period of the last 3 years, we see it is relatively greater, 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.'

Using this definition on our asset we see for example:- Looking at the average time in days below previous high water mark of 212 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 (37 days)
- Looking at average time in days below previous high water mark in of 76 days in the period of the last 3 years, we see it is relatively greater, thus worse in comparison to SPY (45 days).
