Although there are several good sources on the Internet for financial and economic information, if I had to pick my favorite it would be John Mauldin’s newsletter. The newsletter is free and is sent out twice a week, with John usually writing the Friday edition.
The most recent newsletter is titled Is it a Bull, Bear or Cowardly Lion Market? It has some beautiful charts that dissect returns over different time periods. Guest author Vitaliy Katsenelson then extrapolates patterns and characteristics. Prior to reading this article I was under the impression after reading Ed Easterling’s book Unexpected Returns: Understanding Secular Stock Market Cycles that a secular bear market was range bound. Vitaliy digs deeper into those time periods and then labels it range bound. Interesting stuff.
The best charts can be found over at Crestmont Research. Be close to a high quality color printer when you see these charts. It is a goldmine of financial data.
