Stocks closed at a record high last Friday, March 7, but they had no such luck this week, enduring their worst weekly fall since January. The main culprit in this decline is the ongoing crisis in Ukraine’s Crimea region, as talks with Russia failed to end a standoff there. ???Everyone is watching this Ukraine situation, not knowing what to make of it,??? John Carey, a fund manager at Pioneer Investment Management Inc., a Boston-based firm, said. ???Consumer confidence was a little low although I think people still need to coincide what the weather has done to the data. People are realizing the market is OK if we don???t have a real setback internationally.???
