Both index can, and will go either up or down (I think more likely down as I smell some bias), but one thing is very likely: the broad US market will perform better than Tech sector composite. The extreme growth story of last 6-8 years is over!
1. If you are in general, short Nasdaq100 rather than SP500
2. If you'd like to trade the relative performance, then buy ESU6 vs selling NQU6 (Sept Spread)
