Most general-purpose financial news sites give short shrift to the bond market. Sure, you can find the latest Treasury market yield curve (rates graphed for different maturities), but beyond that it’s generally stocks, stocks, economic indicators, and then more stocks.
Since the bond market has many types of securities, and many times more individual securities available than the stock market (there are 50,000 municipal issuers alone), it behooves those considering individual debt securities to educate themselves on their options. Thankfully, there are a number of Web sites of primary interest to bond investors and advisors interested in the bond market.
Investinginbonds.com is run by The Bond Market Association, with basic educational information such as: taxable equivalents; an excellent glossary with 400 bond-related terms; guides to various types of bonds (munis, corporates, mortgages, CMOs, etc.); and links to numerous pricing sites, as well as Spanish language info.
Bondmarkets.com, the main site for The Bond Market Association, has more in the way of pricing, current news and regulatory issues, and also links to research reports (for a more sophisticated audience than Investinginbonds.com), with news particularly heavy on bond issuance.
Bondsonline.com has a well-laid-out site with links to all kinds of bond information, questions answered, news, and commentary (albeit a lot of their most interesting and centrally located story links are for paid newsletters).
