But even if Draghi does unveil what the market is anticipating, the question is, will further easing measures be the solution to Europe's economic malaise? Sure, it worked in the U.S. but does that mean it will work in Europe?
Some traders say no. An economic recovery takes more than just quantitative easing. Each individual economy needs to work on structural reform – policies to help revive their own respective countries.
And while each country says it's working on a plan – some analysts say more work can be done. Less reliance on ECB and more action from individual country leaders is needed, they say.
Despite what is most likely going to be a slow and drawn-out path to recovery, there are some investors who are bullish on Europe.
In fact, Morgan Stanley writes that it is positive on European equities for 2015. Analysts there expect a pick-up in economic momentum, and 10 percent earnings per share (EPS) growth.
One of the factors that should help earnings this year is a weaker euro. The single currency is currently trading at a multi-year low against the US dollar.
"A key component in our 10 percent EPS forecast is the likely currency tailwinds that European companies will enjoy next year. Our FX (foreign exchange) strategists expect EUR/USD to reach 1.12 by the end of 2015," writes Graham Secker, Morgan Stanley's Chief European Equity Strategist.
