We are surrounded by cycles. Seasons, sun, moon, menstruation, sine waves, four stroke engines; wherever we look we find cycles, and use them. So, is it small wonder that we look for cycles in other things? After all, we have looked for, and found cycles that affect the weather (sunspots) and can be used, to a certain extent, to predict weather variations. El nino is another one.
There are plenty of things which are clearly not cyclical, though. Our life on this planet is one. It is a continuous journey, which has some cyclical aspects, but there is nothing to suggest that because someone visited Italy, went bankrupt, won a million dollars on lotto, got married or dug the garden on 26th March one year that these events will be repeated at all, let alone in a cycle.
So why should we expect to see rigid cycles in financial, political or social spheres? Atheists might expect that there will be cycles in human emotions just as there are some physical cycles; theists might expect there to be cycles because that is the way their god designed things, and they believe that god made him/herself in their image, and therefore is like them. Sure, let’s look for them, but let’s also define what we expect the cycle to look like, and what characteristics it should have, to be accepted as a cycle.
What I want is for the cycle, if it exists, to be a useful predictor of what will happen so that it can be used for successful investing. Therefore it must show consistent results. It must be right every time. There cannot be any ambiguity (are we in 2 of 4 or 3 of 5 type stuff; this is useless). It must also, therefore, be immune to goings on in the market or political arena. Or, alternatively, be an integral part of those arenas, which tends to imply that everything that happens was already ordained (predestinational Christians will like those cycles). It must also be predictive. Excuses that are available with 20/20 hindsight as to why the cycle missed the bottom by a month invalidate the concept of a cycle. A sine wave that is not quite a sine wave is not, well, a sine wave! A cycle which is consistently accurate only for a month into the future is great! A seventy year cycle which calls the end of a bull run six months before it rhino horns is useless.
