This move has started to push COST into near-term breakout territory, since the stock is challenging some overhead resistance levels at $102.40 to $103.51. At last check, COST has hit an intraday high of $104.43 and volume is well above its three-month average action of 1.6 million shares. Traders should now look for long-biased trades in COST as long as it's trending above $102.40 to $103.51 with strong upside volume flows. I would consider any upside volume day that registers near or above 1.6 million shares as bullish. If COST can maintain that trend, then this stock will have a great chance of trending north of $110 in the near future. Keep in mind that today's action has pushed COST into new 52-week-high territory, which is bullish technical price action. Costco is one of Warren Buffett's holdings as of the most recently reported period.
