The Kitchin is 42-54 months in length. For convenience we have used 42 months in our discussion (measured bottom to bottom). The up leg of the Kitchin tends to be longer than the down phase. Of the 42 months the up phase will normally take 2 1/2 years (30 months) and the down phase 12 months (or more). So the cycle is not perfectly symmetrical as depicted on my charts.
The Kitchen cycle is actually a business cycle (sometimes called the inventory cycle) that we apply to stock analysis. The Kitchin cycle is often mistakenly called the 4 year cycle. The Kitchin cycle is composed of shorter cycles. One third of it as a sub-division (14 months or around 300 trading days). Each third of a Kitchin cycle is made up of 3 Wall cycles (about 4.5 months or 100 trading days). Each third Wall cycle tends to be the weakest in a group of 3 - that is the Wall that is within the downside of the 1/3 of a wall cycle so we see the impact of the 1/3 sub Kitchin cycle. So within the Kitchin cycle the 3rd, 6th and 9th Wall cycles will be the weakest.
The reason to emphasize the Kitchin cycle is we are now 3 years plus into it and should be entering the are of maximum downside pressure (the last 1/8 or 6 months of the cycle). Earliest bottom date could be 2nd week of September. If the cycle runs long it could be later in 2012 or early in 2013 before it bottoms. Given the expiration of Bush tax cuts, the payroll tax deduction, and the sequestering of funds starting in Jan 2013 it may run long.
Here is an ideal representation of the Kitchin cycle from the bottom in Mar 2009:
As you can see from the chart we should be in the "hard down" phase of the Kitchin cycle starting by mud-April. This aligns with Nenner's prediction of a top by then..... So I expect we could see a significant top in April.
Focusing in and looking at the 1/3 Kitchin cycle we see that we are in the 8th (of 9) Wall cycles within the Kitchin cycle. Each Wall cycle is about 4 1/2 months so the current (8th) wall cycle should bottom in late April. Then we go into the 9th Wall cycle (3rd in a group of 3) which tends to be weak. This is rational as the Kitchin cycle should be moving hard down. 4 1/2 months from late April puts you into the mid September time frame where we will start looking for a bottom. As mentioned above - there are tax ramifications Jan 2013 which could extend the down leg of the Kitchin cycle (42-54 months and we are using 42). Note: Many refer to this as the 4 year or presidential election cycle.
