In this daily bar chart of AA, below, I see a basing pattern. The shares made a "left shoulder" in July and a "head" in late September. I can see a complex "right shoulder" in December and February. AA has been trading around and on the 50-day and 200-day moving average lines. The trading volume increased around the head and has been more active in the months since.
The On-Balance-Volume (OBV) line shows strength from September and tells me that buyers of AA have been more aggressive than sellers. The Moving Average Convergence Divergence (MACD) oscillator is slightly above the zero line.
