The news, terror related or otherwise, doesn't move the markets. I know most won't belive it.
Read my little post on this from another thread here:

I'll recap here: Event A caused 'investors' to sell stocks today blah balh blah blah blah.
Nice story. Pick any event that coincides with the markets move and label it causal. It sounds right. It's bullshit, bullshit, bullshit.
The stock market has not had a significant setback in months. An obvious bull run started in 10/02, that is 18 months. The markets have been unable to break thru the highs made in January. In other words the market has met 'resistance', which means new buyers are becomming scarce. Bullish sentiment has never beeh higher for a longer period. NEVER! Everyone has thrown all their money at the market already is what this says.
In other words a moderate selloff now is to be expected, at least. Or maybe expected is the wrong word. A selloff in this period is well within the probabilites established by market history. History says a very significant top my be forming. Maybe yes, maybe no. Well within the realm of possibility. If so nobody in 6 months will recall the Madrid bombing as the 'cause' of a bear market.
Markets move on the flow of money into and out of them. There is never any one 'cause' for these inflows and outflows.
