$SOXX is about to close under its 100-day MA — same thing happened at the March and July lows, and both turned out to be bottoms. But here's the catch: those times it also pierced the lower Bollinger Band. Right now we're still above the lower BB (sitting at 479), so I don't think today is the bottom. Likely more downside before we get a real bounce. Watch that 479 level — if we tag it and hold, that's when you start looking for a turn.
