The market is holding its breath waiting to see what happens in Europe.
The European Summit meeting is June 28-29, which may cause some cross currents into the weekend.
This week is also the end of the second quarter.
The US Supreme Court is also expected to overturn a portion of Obamacare on Thursday. That may produce a brief but sellable rally ahead of the EU and the weekend. Very hard to say what will happen in these thin markets.
Next week Wednesday is the US July 4 holiday.
