From a technical perspective, AJG gapped higher here right above its 50-day moving average of $35.68 with heavy upside volume. This move is quickly pushing shares of AJG within range of triggering a major breakout trade. That trade will hit if AJG manages to take out some key overhead resistance levels at $36.85 to $36.87 and then once it clears more past resistance at $37.16 with high volume. Traders should now look for long-biased trades in AJG as long as it's trending above its 50-day moving average of $35.68, and then once it sustains a move or close above those breakout levels with volume that hits near or above 593,788 shares. If that breakout triggers soon, then AJG will set up to enter new 52-week-high territory once it takes out $38.24. Some possible upside targets off any move above $38.24 are $40 to $43 in the near future.
