I think a pullback of some kind should be close for AAPL:
- Gap up, Doji plus volume surge, so it could be an exhaustion gap.
- ChiOsc is way too high. See dashed red lines for what happened in the past when ChiOsc is this high.
- Could be Bump and Run Reversal, i.e. the recent push up is much steeper than the previous push up channel which usually is not a good sign.
- iPad 3 release is on March 7, take a look at what happened after iPad 2 was released on March 2, 2011.
An interesting thing about AAPL being the 6th stocks in the $500 Billion Club is all the previous 5 stocks were down a lot as soon as they stepped into the $500 Billion Club. The following statistics are from Sentimentrader.
Another interesting thing is the SPX was at or very near a 52-week high at the point each of the stocks reached $500 billion. As we can see from the chart below, also from Sentimentrader, every time, the index was within days of peaking.
