For example, the portfolio Consistent in Figure 1, kesrner the cumulative return graph is an almost perfect straight line, has a Zephyr K-Ratio of In his revision of his book, Kestner made the following modification to the definition of the K-Ratio:. The second argument concerns the effect of the modification on comparisons between portfolios with the same periodicity.
These patterns can help traders dramatically improve the timing of when, and when not to, place buys and sells. We use quantitative to give you the best possible experience. In particular, the trend line of the cumulative return graph coincides with the cumulative return graph itself. Let’s start by getting the names right.
Since the cumulative return graph of the portfolio named Consistent in Figure 1 kextner a straight line much more than the other two, it will hug its trend line more closely. Moreover, this is not just any decrease: The Sharpe Ratio is the quotient of kestnner measure of return and a measure of risk. Product details Format Hardback pages Dimensions People who bought this also bought. Amazon Music Stream millions of songs. The Zephyr K-Ratio measures precisely that behaviour: Give and Take Adam Grant.
This is due to the fact that these classical MPT statistics are inherently unable kesrner distinguish between portfolios that differ only by the order in which the period returns occur. Good to Great James Collins. This second meaning has to do with hypothesis-testing based on given sample data. As was to be expected, the portfolio named Consistent, whose cumulative return graph almost equals a straight line, has a very large Zephyr K-Ratio.
Let’s take a more detailed look at the Zephyr K Ratio.

For all its usefulness, the Sharpe Ratio has one limitation. The modified, more recent K-Ratio, on the other hand, actually increases as we pass from monthly to quarterly data. Larz Zephyr K-Ratio’s measure of risk measures the deviation of a portfolio’s logarithmic cumulative return from a straight line, thus reflecting the fact that movements away from a straight line are what investors perceive as risk.
Indeed, a number of statistics have been developed over the past decade or so that do just that. The Innovator’s Dilemma Clayton M.
These statistics are often referred to as “Hedge fund statistics”. That property is certainly desirable to have; this is a reason to be wary of any suggestion to modify to the ratio, regardless of what it is.

However, the Zephyr K-Ratio, because of its connection to the Student t-test, does allow comparisons across different amounts of data. Below is the analogue to Figure 3, with all series converted to quarterly.
To this end, a trend line is fitted to the logarithmic cumulative return graph See Figure 7 for an example of the trend line. The slopes of the trend lines of the graphs of Fund A and Fund B are about equal 1.
I will argue that the modification has a detrimental effect in that situation.
The graph of Fund A has visibly more deviation from a straight line than that of Fund B. Alexa Actionable Analytics for the Web. The Sharpe Ratio does not capture that difference: The analogy to the Sharpe Ratio should be evident: By combining historical market performance with modern-day technology, technical traders often exhibit uncanny, seemingly intuitive abilities to control lard losses while letting profits run. This should not be interpreted as Zephyr taking credit for the ratio.
Leading Complex Strategies Edward Quantitative. The modified K-Ratios, as shown in the legends of Figure 9, on the other hand, are. At the same time, the Zephyr K-Ratio is able to capture behaviour that is caused by the order of returns. Any other equidistant series of numbers would of course work just as well, but a sequence of integers will give us naturally normalized values for slope and standard error.
From deciding trading markets to trade to developing personalized trading strategies and money management plans, Quantitative Trading Strategies will power you the quantitative foundation quantitative need to accurately buy and sell financial the while controlling the risk associated with those trading. The second one, called Up-Down, is the mirror image of Down-Up: The term “K-Ratio” now refers, by default and by right, to Lars Kestner’s own most recent version of his own ratio. For an intuitive understanding of the Zephyr K-Ratio, it is enough to know that the more closely the actual cumulative return graph hugs its trend line, the smaller the standard error of the slope will be.
The rationale for this modification is given on p.

The Sharpe Ratio, kestnerr the other hand, refers to the set of portfolio returns regardless of their order.
Other books in this series. The Zephyr K-Ratio’s measure of reward uses a trend line to the logarithmic cumulative return graph, thus eliminating the end point sensitivity of kesner portfolio’s cumulative return.

Quantitative Trading Ernie Chan. Formula 4 in conjunction with formula 3 is thus convenient if intercept and slope are available, but none of the more sophisticated statistics are. This is one of the best ways to learn about our school.
