Taken from stocks and commodities, ext. 00:11 (459-462): The Coppock Curve by Elliott Middleton
"We are creatures of habit. We judge the world in terms of what we experienced. If you're shopping for a mortgage and rates in teen years (as they were in the early 1980s), then reduced to 10 %, we are happy. If, however, they have 8% and then increased to 10%, we're disappointed. It all depends on your perspective.
The principle of adaptation-level applies to how we judge our level of revenues, stock prices and virtually every other variable in our lives. Psychologically, relativity prevails ..
Simplest forms
The moving average is the simplest form of adaptation level. Moving average crossover rules clearly signal the beginning of the period returns outside the norm, whether positive or negative. This makes moving average crossovers useful to traders who wish to gain a boost in entering or exiting stocks or funds.
The oscillator, based on the level of customization, although in a slightly different way. Oscillators generally begin by calculating the percentage change in the current price of some previous price, where price is the previous adaptation level or reference point. The mind is consistent with the percentage change, because they are coming back. If you bought Microsoft Corp. stock (MSFT) at $ 50 and it goes to $ 80, will make 60% before dividends. If you bought Berkshire Hathaway Inc. (BRK) of $ 4,000 and $ 4,030 to raises, the same dollar profit, you make 0.75% before dividends. It is the percentage change that counts. Relativity again.
Coppock reasoned that the emotional state of the market may be determined by adding the percentage changes over the past period to get a feel for the dynamics of the market (and oscillators are generally momentum indicators). So if we compare prices in relation to a year - which happens to be the most common interval - and we see that this month the market is up 15% over a year, last month it was up 12.5% over a year and 10%, 7.5% and 5%, respectively, a few months before, then we can judge that the market is gaining momentum, and as a merchant looking for upward crossover of moving averages, we can jump on the market.
