Different ways of averaging are tested on BRCM 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 BRCM.

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. Norman G. Fosback has noted that legitimate signals of this sort will normally be evident through a variety of averaging methods.

Companies In the News

Friday, March 12, 2010: We have news on ConAgra Foods, Inc., ticker symbol CAG. Signs of an over-bought condition have become noticable. Also, there are breaking events concerning Convergys Corporation and Coach, Inc..

From the News Archive: (3/11/2010 ) A favorable event happened at Zimmer Holdings, Inc.. Meanwhile, bad news came from Fluor Corporation (NEW), Automatic Data Processing, and Home Depot.

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.
