Price‐Rate Func:on Example: Security with Positive Convexity Price Linear approximation of price function Approximation error Interest Rate (in decimal) Convexity 2 Debt Instruments and Markets Professor Carpenter Correc:ng the Dura:on Error • The price‐rate function is nonlinear. • Duration and dollar duration use a linear approximation to the price rate function to measure the change in price given a change in rates. • The error in the approximation can be substantially reduced by making a convexity correction. Taylor Series • The Taylor Theorem from calculus says that the value of a function can be approximated near a given point using its “Taylor series” around that point...

...In evaluating the schedule for the project of house flipping for a profit it is determined that the resources necessary for competition are to outsource utilizing local contractors who have been chosen through a competitive bid process. Quotes were sent to area contractors who specialized in the task needed to complete the various aspects of the project. Once the quotes were submitted, the contractors were selected based upon the lowest responsible bid. This process gives all area contractors the opportunity to bid on work and also benefits the home owner by ensuring that they are receiving the best possible price. After the winning contractors were selected, they were then notified as to the outcome and presented with a contractual agreement outlining the specific job and the expectations. After the contractors have been awarded the jobs, the schedule is then set up. The tasks are entered into Microsoft Project and then broke out into the subtasks such as siding, painting, and removing shingles. The tasks are assigned resources which include the specific contractors that will be performing the work. When evaluating the schedule, it is determined that because each contractor is responsible for various areas of the project, there will be an issues with allocation. What this means is that while the contractors who were hired to complete the exterior work can tackle the jobs such as siding and roofing, the contractors who were hired to complete the interior...

...factor affecting asset and liability values is interest rate changes. If interest rates increase, the value of both loans (assets) and deposits and debt (liabilities) fall. If assets and liabilities are held until maturity, it does not affect the book valuation of the FI. However, if deposits or loans have to be refinanced, then market value accounting presents a better picture of the condition of the FI. The process by which changes in the economic value of assets and liabilities are accounted is called marking to market. The changes can be beneficial as well as detrimental to the total economic health of the FI. 6. Consider three Treasury bonds each of which has a 10 percent semiannual coupon and trades at par. a.

...Bond Portfolios 1. Duration can be thought of as a weighted average of the ‘maturities’ of the cash flows paid to holders of the perpetuity, where the weight for each cash flow is equal to the present value of that cash flow divided by the total present value of all cash flows. For cash flows in the distant future, present value approaches zero (i.e., the weight becomes very small) so that these distant cash flows have little impact, and eventually, virtually no impact on the weighted average. 2. A low coupon, long maturity bond will have the highest duration and will, therefore, produce the largest price change when interest rates change. 3. An intermarket spread swap should work. The trade would be to long the corporate bonds and short the treasuries. A relative gain will be realized when the rate spreads return to normal. 4. Change in Price = – (Modified Duration Change in YTM) Price = -Macaulay's Duration1+ YTM Change in YTM Price Given the current bond price is $1,050, yield to maturity is 6%, and the increase in YTM and new price, we can calculate D: $1,025 – $1,050 = – Macaulay's Duration1+ 0.06 0.0025 $1,050 D = 10.0952 5. d. None of the above. 6. The increase will be larger than the decrease in price. 7. While it is true that short-term rates are more volatile than long-term rates, the longer duration of the longer-term bonds makes their rates of return more volatile. The higher duration magnifies the sensitivity...

...Investment Advisory Commission Duration Basics Introduction Duration is a term used by fixed-income investors, financial advisors, and investment advisors. It is an important measure for investors to consider, as bonds with higher durations (given equal credit, inflation and reinvestment risk) may have greater price volatility than bonds with lower durations. It is an important tool in structuring and managing a fixed-income portfolio based on selected investment objectives. Investment theory tells us that the value of a fixed-income investment is the sum of all of its cash flows discounted at an interest rate that reflects the inherent investment risk. In addition, due to the time value of money, it assumes that cash flows returned earlier are worth more than cash flows returned later. In its most basic form, duration measures the weighted average of the present value of the cash flows of a fixed-income investment. All of the components of a bond—price, coupon, maturity, and interest rates—are used in the calculation of its duration. Although a bond’s price is dependent on many variables apart from duration, duration can be used to determine how the bond’s price may react to changes in interest rates. This issue brief will provide the following information: < A basic overview of bond math and the components of a bond that will affect its volatility. < The different types of duration and how they are calculated. < Why duration is an important measure when comparing...

...1. Duration and elasticities (a) (b) Interest rate sensitivity = Typically, the negative sign is ignored. Thus, when Ct remains constant, the interest rate sensitivity of a bond increases as its time to maturity (T) increases. Therefore, the interest rate sensitivity of a bond and its time to maturity are positive correlated. (c) To a zero-coupon bond Typically, the negative sign is ignored. This expression implicates that the elasticity of a zero-coupon bond is equal to its time to maturity (t). 2. Duration and elasticities (a) The higher the coupon payments, the ‘heavier’ the left hand side. To get the ‘system on balance’, we have to move the fulcrum to the left. This would lead to a shorter distance and hence a lower duration. And vice versa, the lower the coupon payments, the ‘heavier’ the right hand side. Now, to get the ‘system on balance’, we have to move the fulcrum to the right. This would lead to a longer distance from the origin and hence a higher duration. (b) Based on the preceding formula, the sigh of duration is positive. Modified duration is considered as a direct measure of price sensitivity to interest rate changes. Thus, the relationship of bond prices to interest rates is negative correlation. (C) -108*2.2*0.25%$-0.594 3. Duration calculations (a) What is the price of the bond?
