...ignore the charts, and decide whether the stock is fundamentally cheap. Buy and wait for the market to arrive at the same conclusion. If stock falls further, and the story hasn't changed, buy more. Repeat. Goes up and gets ahead of itself, then trim.
Doesn't always work of course, but I tend to find this a winning strategy over the long term more often than not. NCC is actually a good example of a stock where this strategy has worked very well over the past decade, and will (hopefully) continue to do so!!
