The Cunning Realist takes a look at limits:
Since the bursting of the technology bubble in 2000, there have been four distinct periods in which the Fed has flooded the system with an extraordinary amount of liquidity in an effort to boost the stock market:
1. Immediately after 9/11.
2. During the second half of 2002 in response to widespread accounting scandals and the meltdown in the corporate bond market.
3. During the summer and fall of last year, just before the presidential election (draw your own conclusions).
4. The past two months.
