  • Valuing Risky Bonds

    In this context, a risky bond is one for which there is a nonzero probability of default.  Conceptually, valuing such a bond is child’s play: you calculate the (present) value of the bond assuming no default (which the curriculum abbreviates VND: Value, No Default), then subtract the (present) value of the expected credit losses (i.e.,…

  • Yield Curve Strategies – Dynamic Yield Curve

    Making Money with Bonds In the article on yield curve strategies in general, I mentioned the two broad ways to make money with bonds: Coupons (more generally, to incorporate synthetic strategies using, for example, swaps: interest payments) Price changes The curriculum breaks down the expected return on a bond in this manner: \begin{align}E\left(R\right) &≈ Coupon\…

  • Dividend Discount Models

    A time-honored method to determine the value of an investment is to discount to the present all of the investment’s (expected) future cash flows, and tot up those present values.  It’s a method we use commonly when valuing bonds, and when valuing projects in which a company is considering investing (e.g., whether or not to…

  • Equity Valuation Models

    The CFA curriculum discusses a variety of methods for estimating the value of a company’s equity.  The approaches, or models, fall broadly into these categories (covered in separate articles; follow the links): Present value models (also known as discounted cash flow models) Dividend discount models (DDMs) Free cash flow to equity (FCFE) models Free cash…

  • Yield Curve Strategies – General

    In 2019, CFA Institute revised all of their Level III Fixed Income readings, and, in particular, came up with a 10-page blue box example that was absurdly complex, which I simplified here. That example’s gone.  Fortunately.  (In point of fact, I’m sorry that the idea is gone from the curriculum, because it was interesting and…
