Interesting Chart

Here's an interesting chart I just came across which shows complete recognition that investors are not heeding historical stock market moves and are not conerned with overvaluation of stocks and the possibility of a market downturn.  (The red lines represent when investor sentiment was measured to be positive; the blue line represents the stock market and whether it was going up or down)...notice where we are now on the right side of the chart; makes me say hmmmmnm.
