Yield Curve Spread Trades: Opportunities & Applications

Two primary yield curve spread strategies are the flattener and the steepener. The risk measure for yield curve spread trades is DV01 (dollar value of a basis point). As the back leg DV01 is greater than the front leg DV01, one must calculate a hedge ratio to result in a DV01 neutral position.


the steepness of the S-Curve, and therefore, the confidence level. Higher correlation among the sub-elements tend to increase the portfolio standard deviation, and therefore a wide spread of slope. Counter intuitive: Higher correlation increases point estimate confidence level. It also increases budget required

The upward slope of the supply curve reflects rising marginal costs; if marginal costs do not rise, the supply curve would be horizontal. You will sometimes see flat supply curves to simplify the graphs in the discussion of monopoly in microeconomics, and to illustrate the possibility of expanding national output (GDP) at low

How do we choose which measures of center and spread to use

A Density Curve is a curve that Is always on or above the horizontal axis, and Has area exactly 1 underneath it. The area under the curve, between any range of values, is the proportion of all observations that fall in that range. The median of a density curve is the equal-areas point, the point that divides the area under the curve in half.

What Do Slope Fields Show You? The solution curves are hiding in the slope field. Given one point of the particular solution curve, you can sketch the graph from that point, in both directions, to see the graph of the solution. The initial value problem 342 dy x dx with y = 1 when x = 0 is shown. Notice how the graph flows

Physics Experiments in Mechanics

In plotting linear relationships, you frequently will be asked to find the slope of the line you have fitted to the data (this slope usually has a physical meaning). To calculate an accurate slope, read a point on the line near each end of the line. Do not. use data points unless they are on the fitted line!!!! That is, choose widely separated

You should express the field in V/cm. (HINT: The field is the local slope (derivative) of the potential. Also, if you choose to use a ruler realize that the above reproduction of this group s results is not the same size as the original, where the grid size was 1 cm).

How to create graphs with a best fit line in Excel

As you can see (and this will be similar to your lab results), not all points will lie on the line. As it says in your Lab Manual: when you calculate your slope, do not use your data points unless they actually fall on the best fit line You can visually see that they could give you the wrong slope.
