Diversify.
Stocks are overpriced by using traditional P/E ratios.
The market can go one of two ways. . .up. . .or down.
In today's weird market it could simply stay were it is until earning go up over time - thus leveling out to a "normal" PE ratio.
Or, something could happen to panic investors and the market could drop back to it's average PE ration.
The Shiller PE ratio chart shows where we are today in terms of company earnings and their stock prices.
http://www.multpl.com/shiller-pe/There's too much money in the system and nowhere for it to go.
So for the time being, it is going into stocks - which are now artificially inflated.
But where else to put the money? That's the conundrum.
