Fin - Breakout - US


The financial glossary from Yahoo! Finance is your A to Z guide to understanding business and investing. Whether you're new to the stock market, an intermediate investor or an advanced trader, you'll find the terms here you'll need to better understand the world of finance.

What types of information are contained here? You can start with the basics -- learn about stocks, bonds and buybacks. If you're already familiar with the building blocks, you can begin to learn about short selling and rate of return. From there, you'll find information about present value, the Treynor index and the capital asset pricing model, just to name a few.

In other words, if you want finance terms, this is the place to go. We've got all the definitions to help make you a more confident investor.


Bonds can seem deceptively simple. All you have to do is buy a bond, wait for the interest to come in at regular intervals, and eventually you get repaid your purchase price, too. Easy, right? Well, not exactly.

While that very simple example can in fact essentially describe any number of bonds, there's plenty of complexity, as well. But don't be alarmed. If you're looking for information on fixed-income securities, we've got you covered with our bonds glossary.

From principal and yields to indentures and munis, you'll find it here. For even more information on bonds, be sure to visit our bonds center. Bonds expertise is just a few short clicks away.


Whether you're looking for information on puts and calls or delta and condors, you'll find what you're looking for in our options dictionary.

These terms can get a little tricky, especially if you're taking your first steps into the world of options and other derivatives. Even for the more advanced traders, our list of options terms is a quick and easy reference on those days something has just slipped your mind or you need to confirm what you already know.

Regardless of your current comfort level, our glossary, combined with our options center, will have you well on the way to successfully and skillfully navigating the options arena.
