World leaders retreated from the snowcapped mountains of Davos this week, returning from the four-day World Economic Forum Annual Meeting. While the confab may not have solved the world’s ills, at least a handful of them came into sharper focus. Chief among these was the issue of Greece’s potential agreement with its bond holders and the EU’s ability to hold together over the next five years. By many reports, the continent’s leaders were given an earful (Dow Jones, Reuters, PBS Newshour) on the need to resolve the crisis quickly. And it sent no small signal when Christine Lagarde of the IMF held up a bag and asked for money (no joke; here’s the picture).

Big questions like the role and function of capitalism were debated, while arguably an even bigger question—whether the world can sustainability support 10 billion people—was also broached. Bill Gates, who spoke on Wednesday, urged governments to continue funding a range of crucial health care projects in the developing world.

These topics fit into the broad categories of global challenges that the World Economic Forum seeks to address, which include Economic Growth, Environmental Sustainability, Financial Systems, Health for All and Social Development. For a bit of perspective, below is a table showing how related indexes have performed over the past year, and over the three trading sessions since Davos ended.
