There's an opinion that the driver of this rally is mainly the expected corporate tax cut; some experts think this can take SPX to about 2400. I'm not an economist but a businessman and I know that any changes bring pain along. I think as we move on with the reforms there will be many shocks. In the holographic universe everything is interconnected.
הערה:
Judging by the open interest in SPY options it looks like we might have already made this week's low. No trade advice, just an opinion.
