Between January 20 and 22, Wynn bought $31.9 million worth of shares at an average price of $55.62, Barron's reported.
The purchase follows an earlier trade in which Wynn bought $63.9 million worth of stocks at an average price of $63.61 between December 4 and 8, Barron's added.
The CEO now owns 11.7 million shares for an 11.6% stake in the company.
"The shares owned by Mr. and Ms. Wynn are subject to a shareholder agreement which requires the shares to be voted together and puts limits on divestitures," Bernstein Research noted, according to Barron's.
Separately, TheStreet Ratings team rates the stock as a "hold" with a ratings score of C-.
Wynn's strengths such as its expanding profit margins over time are countered by weaknesses including deteriorating net income, weak operating cash flow and feeble growth in the company's earnings per share.
