Volume and volatility were at record low levels again this week, leaving traders scratching their heads and wondering what's the catalyst to being it back. TheStreet’s Jill Malandrino and Nicole Urken preview the week ahead and where investors will be focused. Economic data is light as is the earnings calendar, but the key will once again be retail stocks and the strength of consumer spend. The consumer space has been a tale of the "haves" and "have-nots", with higher and lower end retail outperforming relative to mid-tier brands. Stocks to watch included Lululemon, Restoration Hardware and Sportsman's Warehouse.
