Stephanie selling shares

At work, wondered how WWE stock was doing, checked the company news and see that Steph has sold like 113,700 shares since Dec 5.  Almost 50% of her holdings sold seems strange.

It seems strange to a lot of people, as does her cover story of building a new house.  However, you can't exactly put her on the stand and question her true reasons if the story is a feasible one.  Given I know nothing about the stock market I can't really speculate on what her true motivations might be, but it strikes a lot of people as kind of weird and shady.
