BALTIMORE ( Stockpickr) -- Considerable overnight action in Europe is pointing toward a volatile day Tuesday following news that Japan's expanding its euro holdings by buying EU debt.Specifically, Japan plans on buying 100 billion yen worth of bonds from the European Financial Stability Facility (EFSF), a purchase that rings in at around 20% of the total issue. The announcement did a good job of boosting the euro overnight -- that's because the EFSF debt is being used to provide emergency loans to the PIIGS countries. Portugal, which is set to auction 1.25 billion euros of its own debt this week, added to the news mix after its own central bank announced that it'd be willing to seek external support. Ultimately, both of these actions should do a good job of calming at least some of the anxieties that have lingered over the markets since spring 2010. To play into the upswing in sentiment, we'll take a look at three new technical setups this week.
