摘要

确定有四个以上票息期的票息债券的到期收益率分为两步。第一步使用近似公式来获得真实产量的近似。第二步使用一种算法，使第一步的近似值更接近债券的真实收益率。牛顿法是微软Excel“YIELD”函数等应用程序中使用的算法。本文评估了一些常用的近似公式，然后展示了一种通常优于牛顿法的求解算法。

Superseding Newton with a Superior Yield Algorithm

Determining the yield to maturity of a coupon bond with more than four coupon periods is a two-step process. The first step uses an approximation formula to obtain a first approximation of the true yield. The second step uses an algorithm to advance the first approximation closer to the bond's true yield. Newton's Method is the algorithm used in applications such as Microsoft's Excel "YIELD" function. This paper evaluates some commonly used approximation formulae before demonstrating a solution algorithm that generally outperforms Newton's Method.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
