Given the current geo-political climate and the increased volatility we've seen in the global markets this week - including in commodities, currencies and fixed income on top of stocks - it's hard to imagine anyone wanting to go into the weekend heavy on either side in stocks, on the short side in crude oil or gold / silver or overly long of the risk currencies (euro, Aussie, Canadian dollars).  If the geo-political front heats up even more during the weekend, we could see crude up $1 or more, gold / silver up or down huge and the S&P futures up or down 30 more handles.  Traders - especially those in heavily levered markets - need to tread lightly and intelligently into the overnight / over-the-weekend periods these days.  Buyer / seller beware!
