Brett Crowther dials up the chart for Apple (AAPL) following the iPhone makers rise to new all-time highs this week. He says the pop to the upside is curious as it hasn't had a lot of volume. On the 5-day chart, he indicates the rising RSI momentum could bring some more energy to this move. On a longer-term chart, he uses a line at $258 acting as an area of resistance over the past year with $245 as near-term support. Brett says an upward flag could suggest $280 as a possible test if the bullish move continues.
