This is just my idea, PPI data is out as expected. Previous fear of 100bps rate hike probability is kind of easing down now. Which likely suggest yesterday's market was pricing in likelihood of 100bps hike, and now heading for neutral. And when the actual news of 75 bps hike is out next week after the FOMC, we might rally to maybe 4200~4230 range. That is when I will be taking long profit and look for short opportunity
