From Taki Tsaklanos: Most historic charts are fascinating, and the Dow Jones Industrial Average (DJIA) 100 year chart is certainly no exception.
While many are talking about extreme valuations of stocks, the Dow Jones 100 year chart suggests U.S. stocks are nowhere near extreme levels. That does not tell anything about a correction, or timing thereof. It simply suggests that the Dow Jones has upside potential before reaching extreme levels.
