This page looks at the predictive abilities of different methods of averaging applied to DGX stock prices. Techniques available include moving weighted or exponential averages of various periods and the family of MACD (Moving Average Convergence Divergence) indicators.

Unfortunately, some of the most popular indicators of this type can prove to be the worst forcasting indicators. The effectiveness of these methods as applied to DGX stock price trend evaluation is tested on the next page.

Green is the 20 bar moving average, while the 200 session average is red. Often the simple unweighted moving averages seen in this plot will give a more accurate indicator, with fewer false signals than some of the supposedly more sophisticated techniques that we test below. It is always possible to fine tune an exponential or other weighted average so that it seems to outperform a simple average in a given situation. However, over-tuning can increase false and misleading indicators. A good un-ambiguous signal will be noticable through a variety of averaging methods, including some of the most simple.

	In the news, Monday, November 15, 2010: A favorable condition has developed with Sprint Nextel Corporation, ticker symbol S. Also, there are breaking events concerning Abbott Laboratories (ABT) and Cree, Inc. (CREE)

MACD analysis would appear perfect for overtuning, since it may use any of an infinite number of averaging methods and coefficients. In addition to crossover signals from various moving averages, analysts frequently add a trigger line based on some average of the first two averages. Here we depict the results of 12 and 26 session Exponential Moving Averages. The exponential coefficient used here is .18. There is nothing magic about these parameters, but these are frequently seen.
