Stocks slipped into the red on Monday morning as investors digested this weekend's elections in Germany along with the uncertain outlook for monetary policy in the US.German Chancellor Angela Merkel's CDU/CSU party won 41.5% of the vote in the federal elections this weekend after winning 311 seats in the Bundestag, though this was four seats shy of an absolute majority. Meanwhile the current coalition partner, the Liberal Democrats (FDP), missed out of the 5% minimum threshold and will not be represented in parliament meaning that Merkel is left having to build a new coalition with either the Social Democrats (SPD) or the Green Party, who won 25.7% and 8.4% of the vote, respectively. "Despite Merkel winning her third term at the helm of Europe's biggest economy, the votes came in slightly short of an overall victory. It will now be up to Merkel to convince leftist rivals to join a coalition government," said Financial Sales Trader Lee Mumford from Spreadex.
