Its when things look good that one has to worry. On Dec 2007 I remember there was all this talk about the fantastic bonuses they were giving out on Wall Street. It scared me so much. In the summer of 73 they cut the hrs on the NYSE. No trading. That was a good sign.
Being a contrarian is good. Except when it is not. Lost quite a bit on small regional banks (many went under).
Never take any advice seriously. Even so - things are looking good. 70% think country on the wrong track. This is vital - because it lets the market continue ever higher.
