Calm Before The "Storm"

The Dow closed sideways today as I have expected before tomorrow's FOMC release. This is somewhat of a tradition no matter how predictable the FOMC release is going to be. Looking at the internals, advancers still led decliners by 2 : 1, indicating a bullish undercurrent ahead of the FOMC release. What worries me most about tomorrow's move is that, at the time of this writing, the Chinese Market is already down by more than 2%... will it cause another Feb 27 ditch?
