My hypothesis of things to come:
1) This recession rebound will be much different and much faster than others because of the unprecedented amount of money that is being pumped into the worldwide monetary base.
2) However, since the money is being borrowed at ridiculously low interest rates (i.e., under 2%), there will not be an ensuing problem of inflation. This flooding of money into the system will primarily hurt savers, people on fixed income, and countries that are forced to fund deficits, because they have no choice (e.g. China, Middle-east countries, etc.), however, it will cause a global asset inflation. Not as bad as the previous one, since governments will prohibit excess leveraging allowed by.
3) It is impossible to predict a bottom, however, the professionals are going out of their way to spread fear among the public via their analyst calls (e.g., GM target is now zero), "leaks to the press", and the steady parade of doom and gloom on CNBC, and the Wall Street Journal. A sure sign that the professionals want to begin accumulating at cheaper prices.
4) All of the money entering into the system will eventually move into assets, causing a sizable rebound in all asset classes. I estimate between 25 and 50%. However, the stock market will not reach prior highs (within a couple of years), since baby-boomers and others will flee the market as they cash in their holdings and are happy with reduced losses.
5) The stock market will flounder with other sizable dips and rebounds for many years, going essential nowhere, until de-leveraging has run its course and institutional and personal savings are become more in-line with debt. This environment will put to rest the ridiculous "buy and hold" philosophy and put financial planners out of business as they should be.
