Technical Summary: The five year chart of WPL looks remarkably similar to the one year chart and seems to be just an 45 extension. The stock of WPL has moved largely within a trading range during this period. This might be one for classical moving average trading. e.g. buy when the stock moves above its 50 day moving average and sell when it moves below. Following this principle would have provided the trader with quite a nice bit of action on the one year chart. On the basis of this the trader would have recently entered a new position as the stock has recently legged above the line.
