Arthrocare Corp

For today's chart we've chosen to take a look at Arthrocare Corp. (Nasdaq:ARTC) because the company's better-than-expected earnings helped send the price beyond the barrier of an ascending triangle pattern. As you can see from the chart below, this stock has had an impressive run over the past several months. We find it particularly interesting how most of the momentum occurred once the price was able to surpass the resistance of the previous swing high. Today's large spike in volume is suggesting that the upward momentum is still strong and that it would not be surprising to see this stock continue to move upward.
