Investors sell off prior to Trade Balance announcement

There was a sell off after hours yesterday as you can see from the chart below.  The sell off was gradual  up until 9:30, then you see a deeper sell off.

You can see in this chart the volume and depth of the sell off at 9:30.   It started in full force at market open.  This tells me that others can see the impact to the economy from the worse than expected trade balance numbers and the slow down in China imports.

Should be interesting how the market handles this news in the coming days, as previous bad news was blown off almost the same day with midday or end of day reversals (like on July 29th with the initial claims)
