Sure they will. The central bank should not be buying any bonds. These central banks create money out of thin air and then buy these corporate bonds and under whose oversight? The companies turn around and buy back their stock in order to puff up earnings. The managements hit their earnings per share numbers (because of less shares outstanding) and get their bonuses and stock options.
The problem is they are buying back stock at a time when all these stock markets are overvalued. This is not going to end well. Nevertheless, as long as this nonsense continues the stock market can continue higher. As I said in this weeks podcast I expect the market to defy peoples expectations on how high it will go before this thing ends.
People need to be aware that if you have money in the US market you are picking up dimes in front of a steamroller. The market is at historically overvalued metrics and the only thing propping it up is schemes like this. As long as you understand then party on I guess.
