Different ways of averaging are tested on YHOO stock prices for their ability to predict trend movements. 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 next page tests the effectiveness of these methods as predictors of future prices for YHOO.

The 200 session average is red, the 20 bar, green. The un-sophisticated moving averages plotted here are un-weighted, but they still may return better results than many of the more popular, highly tuned averages seen in some of the following sections. Commonly, speculators will use exponential averages or weighting techniques to emphasize the most recent data. But past a certain point, such front weighting can dramatically increase false signals. Norman G. Fosback has noted that legitimate signals of this sort will normally be evident through a variety of averaging methods.

	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.
