I think what's going on is partly the share buyback ($750 M authorized). WU has a confirmed history of executing on authorized buybacks. The price leveling at 14, 14.5, and 14.7 suggests limit orders or banded orders by a large buyer.
Hedge funds that bought 9 months ago (there were at least three) might also be averaging down.
Beyond that, there is no new event of which I'm aware, but those are two powerful engines. Earnings in about 5 weeks. My expectations are positive.
