Based on a Jeanty Buy pattern. For a description of the pattern I am talking about, take a look at http://www.wikinvest.com/image/LUV_BUY.jpg and you should be able to see all the components of the pattern. For an example of a recent signal based on a similar pattern, check out GOOG on http://www.wikinvest.com/stock/Google_(GOOG)/Bulls and view the article with title "BUY: Target $461.90 "
Here is the pattern for AES:
You should be able to recognize the 4 components of the pattern and compute the target price of $14.91. Based on en entry price of $13.21, the closing price on 9/19/08, this would mean a potential gain of $1.70 or 12.87 percent.
