The market will likely continue to chop around until the FOMC rate announcement on Thursday. Although the market internals and recent price action started to show a slight bias toward the upside, but this slight bias can be easily reversed by the FOMC rate decision. Therefore, until the FOMC rate decision has been announced, one should remain cautious.
