Facebook shares have been on a tear, up 40 percent over the past 12 months on growth across all its metrics. But that growth is projected to slow way down in light of tough comparisons and a steep jump in expenses.
On Wednesday afternoon Facebook will be under pressure to continue its streak, and answer key investor questions about mobile, video, international monetization and its plans for other apps. These key growth areas are in particular focus in light of Facebook's warning last quarter that it expects expenses to rise between 50 percent and 70 percent this year.
