Even though American Express ( AXP) has gotten buoyed alongside the rest of the financial sector in 2013, most of the excitement came in the first couple of quarters this year. Since then, shares have been slugging their way sideways ever since the start of the summer. But this stock is still tradable. Here's how: >>5 Stocks Triggering Breakouts on Big Volume Like Netflix, American Express is currently in a channel of its own, bounded by horizontal resistance at $78 and horizontal support below shares down at $72. The key difference between the two charts is the fact that AXP's channel is completely horizontal, unlike the uptrend in NFLX. While that tells us that the bias is less heavily skewed towards buyers, there's still a trade in this stock thanks to the rectangle in shares. The rectangle gets its name because it effectively "boxes in" a stock's price action between two horizontal levels -- when a stock breaks out from the range, it becomes tradable. So the buy signal for AXP comes on a breakout above the $78 level, whereas a sell comes if shares fail to catch a bid and fall through $72. Until AXP exits the consolidation, stay away.
