Let's check out the charts and indicators to see the stock's overall health.
In the daily bar chart of ABBV, below, I can see that share prices have spiked higher Thursday. ABBV trades above the bottoming 50-day moving average line and below the flat 200-day moving average line.
The trading volume looks like it has been more active since January but the On-Balance-Volume (OBV) line has moved lower from December and suggests that sellers of ABBV have been more aggressive than buyers. The Moving Average Convergence Divergence (MACD) oscillator has just moved above the zero line for a new outright buy signal.
