Hamilton, as usual, is trying desperately to make a bearish case out of an obviously bullish indicator (being primarily, a short-seller, I wish he were right, but I don't think he is). I think the high P/C ratio is much more straightforward and easy to explain. People are very bullish on the market, but very worried, at least for the summer, about terrorism. W/o terrorism, the market should soar. If something really bad does occur, though, the drop may be so drastic that puts will actually come to the rescue...
