@ Sniper, Quantitative Easing is a gigantic tsunami of Cheap Money capitalism has even seen. it is so big that it can create inflation and even drop the dollar's value. Just think it like this, total market cap of Indian stock(total) is just below 1 Trillion US$. and Fed in pumping 1 trillion per annum into US Debt market. sudden stop has been proven fatal to the value of the stock in US, for more detail look at the chart below.
This time its specil because instead of stopping the QE program, they decided to stop it slowly. maybe thats why we havn't seen any suddent crash of 10-15% yet.
Goldman Sachs says in his report recently that there is a possibility of 10-15% stop by october, but again who knows??!!
