This monologue podcast is a finance lecture focusing on bond valuation. The speaker begins by discussing the importance of breaks and then proceeds to cover fundamental bond valuation concepts, including calculating bond prices using Excel and financial calculators, understanding yield to maturity, and differentiating between clean and dirty prices. The lecture then delves into more advanced topics such as bond price trajectories, zero-coupon bonds, and various yield measures (current yield, yield to worst, etc.). Finally, the speaker explains linear interpolation (matrix pricing) as a method for estimating bond prices and concludes with a case study on Walt Disney bonds and an overview of a bond trading simulation. A key takeaway is the strong recommendation to utilize Excel for bond calculations rather than manual formulas or even financial calculators, reflecting real-world industry practices.
