Nouriel Roubini warned on Monday that certain key developments would exacerbate the downside risks to global growth in 2013.

“Until now, the recessionary fiscal drag has been concentrated in the euro zone periphery and the U.K..

Roubini said the rally in global markets that begun in July was now running out of steam as global growth slows and valuations look stretched.

“Price/earnings ratios are now high, while growth in earnings per share is slackening, and will be subject to further negative surprises as growth and inflation remain low.
