Technical Summary: Interesting 5 year chart for SPK. The stock has currently moved towards its all time highs that it has found on two previous occasions. The question now is whether the stock can move through this into new all time highs. The direction of the 50 day moving average has been trending up since May and the stock has been buyable when it moves back to the 50 day moving average. If it does not break through to all time highs then it will signal a continuation of the range bound action that the stock has moved within for the last few years.
