There is a longish but excellent article by John Hussman which I would urge you to at least skim. In it, he calls for an 80% probability of a crash next year (and this from a man whose historical returns over the past decade have been impressive). Here is a choice snippet:
Whether or not I have focused too much on probable “second-wave” credit risks is something we will find out in the quarters ahead – my record of economic analysis is strong enough that a “miss” on that front would be an outlier. What I do think is that over the past decade, investors (including people who hold themselves out as investment professionals) have become far more susceptible to reckless myopia than I would have liked to believe. They have become speculators up to the point of disaster.
Frankly, I've come to believe that the markets are no longer reliable or sound discounting mechanisms. The repeated cycle of bubbles and predictable crashes over the recent decade makes that clear. Rather, investors appear to respond to emerging risks no more than about three months ahead of time. Worse, far too many analysts and strategists appear to discount the future only in the most pedestrian way, by taking year-ahead earnings estimates at face value, and mindlessly applying some arbitrary and historically inconsistent multiple to them.
