Outlook from a technical point of view:
Except for a smaller consolidation phase in the past week, the Apple share rose from the February low without major corrections to north. At this new all-time high today some market participants likely will take profits.
After the recent rally, bulls will take a deep breath. Profit-takings are expected to start a consolidation phase, or even minor technical corrections, in the coming days.
The risk-return on the long side therefore is unattractive for the coming trading days. It's better to stay on the sideline and look for the expected setbacks (preferred target range 173-175 $) to start a long line-up from this level.
