I'd watch for exceptionally high volumes to drive these stocks to even higher levels at this accelerated pace for the near term, as has been the case since June of last year. Otherwise, we may see a leveling off of the buying, as was the case this past week on AAPL, as shown on the 1-Week graph below.
And, as I've mentioned in previous posts (more recently here), Technology holds the key to overall U.S. equity strength, in my opinion. Until major weakness strikes these five major tech stocks, in particular, we're likely to see that continue.
