Article development
I expect to take a few weeks to work on this article before it will have a adequate amount of information. --Chakreshsinghai (talk) 01:45, 17 June 2008 (UTC)

Some issues...
... that I found in this article are: --Maciek.kolbusz (talk) 18:08, 7 December 2017 (UTC)
 * In section Dynamic Cycles it says that 'the following steps should be applied' while what follows is just one of many methods of finding cycles in a time series.
 * In the same section the referenced book by Lars von Thienen is actually a software manual for Wave59 - the product by the same author.
 * In the same section Step 3 it says 'research results have shown' - what research? whom by? what results?
 * In the same section it is not specified what does 'an adapted Goertzel algorithm' really is.
 * Further in the same section it says about the Bartels test, but this is the test of cycle significance by Julius Bartels, while the citing refers to the paper on test for randomness by Robert Bartels.

This statement:

Research results have shown that an adapted Goertzel algorithm is most suitable when it comes to detecting cycles in financial time series.

was taken word-by-word from the referenced von Thienen's book, p. 52. The author further wrote:

[...] I do not want to publish my mathematical and statistical results here.

Therefore the research results were not published and the statement refers to author's private research that cannot be verified. In my opinion this makes that statement unusable for the Wikipedia article and it should be removed or replaced.

Stock Market Cycles is a very broad area, so focusing on a single book by one author, and that too a non-scientific one, is in a way harmful to the subject and the readers. — Preceding unsigned comment added by Maciek.kolbusz (talk • contribs) 16:51, 16 December 2017 (UTC)

Request
There are quite a few studies that have established the presence of annual seasonality internationally. Would someone locate and summarize them?--Chakreshsinghai (talk) 03:43, 13 August 2008 (UTC)
