Here is what happened:
1. Markets crashed in September and October because of the brutal de-leveraging that is occurring in the financial system and to a lesser extent fears about a bad recession.
2. Markets usually can only move so far without alleviating the pressure moving the market. The first three weeks in October were amongst the worst weeks ever and markets became cheap. That exhausted the sellers and brought in the buyers.
3. As the sellers exhausted themselves, selling pressure eased, causing a snap-back rally. Notice I have said nothing about politics yet.
4. The markets rallied in front of an Obama victory. Markets are
forward-looking and move in front of events. The market did not necessarily want Obama to win - a McCain victory would have lead to a continued bounce - rather, the market was rallying because of
clarity. In other words, the market hates uncertainty and was going to rally no matter who won.
5. The market "sold the news." Once the news hit that Obama won, traders sold. This is a natural Pavlovian response and occurs throughout the market commonly. However, two other things have pushed the market down 10% over the past few days. First, a giant hedge fund in Chicago named Citadel is
liquidating investments as it has to put up more collateral to back its positions. This is forced selling having nothing to do with politics or economics. Second, investors are scared about this morning's nonfarm payrolls number, which will have hit by the time most of you have read this post. Economists are expecting a decline of 200k nonfarm payroll jobs. However, investors are thinking it could be much higher, perhaps 250k-300k. Since investors are worried about the jobs number, buyers have been stepping aside letting the sellers do their thing, causing a drop in the market.
