After a big advance from April to August, Apple (AAPL) turned dull as a tight consolidation takes shape. Notice that the Bollinger Bands are narrowing and a triangle is taking shape. The indicator window shows BandWidth below 5% for the first time since early July. This volatility contraction suggests that traders should prepare for a volatility expansion. Watch 103 for an upside breakout and 97 for a downside break.
