The Psychology Of A Sideways Trend

A fascinating study is the psychology that accompanies a prolonged sideways market trend. It also holds insights into what the future likely holds for stock prices.

When equities get stuck in a sideways trend for several months, investor psychology goes through four basic stages of change: 1.) initially they feel expectant that stock prices will quickly breakout of the newly formed range; 2.) when this fails to materialize sentiment turns sour as stocks drop to the lower boundary of the range; 3.) as stocks continue bouncing from the top to the bottom of the range investors begin to lose interest and eventually quit participating altogether with many selling their stock holdings. This is what forms the basis of a bullish accumulation pattern since the smart-money professional investors eagerly snap up the disgorged supply from disgruntled retail investors. 4.) Finally, as the range is nearing its final resolution, small investors who may, or may not, be invested are thoroughly frustrated at the lack of directional movement.

The frustration that has built up during the period of the lateral trend is released in various ways. Not uncommonly, trading range breakouts are preceded or accompanied by various expressions of mass frustration, including protests, civil unrest or conspicuous acts of violence. If the trading range continues long enough the subsequent release of pent-up tensions can even result in the initiation of military conflict. Witness the collective angst of Americans of all walks of life during the 1970s, a decade which was entirely encompassed by a lateral trading range in the stock market.

In my 20 years in the financial industry I've concluded that nothing exerts as profound an impact on mass psychology (to say nothing of investor psychology) than a prolonged sideways trend in equity prices. Why this should be is open for debate, but I have what I believe are valid insights. In highly developed capitalist nations such as the U.S. the stock market is the single biggest barometer for measuring the collective expectations for the business and economic outlook among all participants. The majority component of the U.S. economy is finance, directly or indirectly. Therefore everything concerning the material prosperity of the nation ultimately depends on the stock market.

It can also be observed that humans by nature are so conditioned to the concept of progress that anything which seems to undermine the longing for growth is viewed with contempt. A sideways trend in stock prices over a long period of months or years is rightfully seen as the antithesis of progress, hence the deep seated psychological frustration which underlies a trading range environment.
