The culprit is US policy, trade war frictions, and the dollar. If Chinese revenues continue to decline, it will have an overall impact on Apple. So I think the investors expect the continuation of the conflict and therefore selling shares ~$190 while they can...
In my view the chart shows the negative investors sentiments.
Support ~ $160 - $165
Resistance ~ $190 - $200
Prediction ~ $150 per share by EOY.
