The SP is reaching a high note here. It is an attempt, in my judgement, to pump up financial assets, led by price manipulation and not any economic fundamentals or legitimate price discovery. It might go higher, but higher from here it looks like bubble territory, if we are not there already.
Overdue for a fairly stiff correction, but do not get in front of it for the sake of your portfolio. I would not underestimate the Fed's willingness to create a new bubble to attempt to counteract the effects of the last two. What else can they do given the hole into which they have dug themselves? It will take a serious financial reform and economic restructuring effort to correct this. Until then the looting continues. 
"what should you do to avoid being an idiot or a swine? Merely this: You should do something great, you should lay aside all the foolishness of a more of less long existence, you should become resigned to the fact that you will seem ridiculous to a race of janitors and bureaucrats if you are to enter the service of Splendor. Then you will know what it means to be the friend of God. The friend of God!"
