AmerisourceBergen (ABC) made a low just before the election and rallied strongly until early March. Prices have corrected to the downside the past two months but this pullback looks like it is over and fresh gains could lift ABC to new recovery highs in the weeks ahead.
If you look at our first chart of ABC, below, you can see prices are below the declining 50-day moving average line and have spent half of April below the peaking 200-day moving average line. Prices have declined the past two months and the On-Balance-Volume (OBV) line has declined, too. Prices are holding above an $80-$76 support zone and the OBV line is holding above its lows. The Moving Average Convergence Divergence (MACD) oscillator is poised to signal a cover-shorts buy signal from below the zero line.

In this weekly chart, above, we can see the price of ABC has been in a sideways pattern since early 2016. Prices are below the 40-week moving average line, but that may not last for long. The weekly OBV line is still above its October low and the MACD oscillator gave a liquidate-longs signal.
Bottom line: Putting the pieces together on ABC leads me to take a bullish stance. Trade ABC on strength and risk a close below $79. Buy a close above the 200-day moving average line at $84 and add on the second close above $86.
