Things got interesting in December when WYNN was removed from the Nasdaq 100, probably due to the stock's performance, but at the same time, Stephen Wynn (CEO, etc.) bought 1 million shares in the open market.
The indices have a habit of removing stocks after the stocks have suffered huge drawdowns and include them after years of serious outperformance, think of Apple's recent inclusion to the Dow Jones in March of 2015. Many stocks that get booted from the indices perform better immediately after than those that replaced them in the index.
Bottom line, WYNN is a long candidate as long as it stays above $64.
