Is the bull trend in tech about to end? What Tech and its volatility index does in the next few weeks will go a long way to answer this question.

This chart looks at the NDX 100 and its Volatility Index (VXN) on a weekly basis over the past couple of years.

The trend for the NDX remains up/bullish. No price action of late has changed this trend! It tested its September highs two weeks ago, and so far those highs look to have held, forming a potential double top.

VXN movement has been shallow the past few months, as it remains inside of a narrowing pennant pattern.

What would stock bulls love to see? A breakout above the September highs and a break of support by VXN.

What would send a concerning message to stock bulls? A break of support at (1) and a breakout of the pennant pattern at (2).
