Invest Skeptically

The FINRA (Financial Industry Regulatory Authority) Market Data site has great summary data on U.S. stock and bond markets. The site includes equity index levels, investment grade and high yield bond index levels, market diaries, U.S. yield curve, news, and economic indicator calendar. It also has links to the TRACE (Trade Reporting and Compliance Engine) bond market data which affords retail investors a new level of price transparency that was not available pre-TRACE.
