I've been monitoring AZ, it made a divergent high back Nov with the MACD, however the MACD was way above zero, and I've discussed this before, that divergence when the MACD is well above zero often does not produce much of a pullback and instead you get another run up, which AZ did.  I commented that a stock is MUCH more vulnerable whenever the MACD  recycles closer to zero and you have the divergence. On that last rally  to 7.5 the MACD had recycled closer to zero while diverging, thus making it more vulnerable this time around and that might be starting to play out

right now you have the 50 day MA here, that's first support- if that area doesn't hold, it may want to pullback to the larger demand zone

the second imageshows the Dow Jones, where I discussed this back in March/April - the divergence in early January didn't produce much of a pullback because it was too far above zero, too strong. However, once the MACD recycled into late March, that finally produced more of a pullback

anyway the point is -whenever you see MACD divergence but MACD is very far above zero, often times it doesn't produce much of a pullback until you get that recycling action
