Wynn Resorts stock is up more than 3 percent intraday after Macau's April casino gross gaming revenue rose 16.3 percent, ahead of analysts' consensus for 15 percent growth.
VIP players led the way in the world's largest gambling mecca, with new resort casinos helping to draw in the high rollers.
"The way investors are looking at it, if they want exposure to the recovery, Macau's Wynn is their way of playing that," said Union Gaming analyst John DeCree in Las Vegas. "For Wynn, about 75 to 80 percent of their profits are coming from Macau."
In August, the $4.1 billion Wynn Palace casino resort opened in the Cotai area of Macau. Sands opened its Parisian Macau resort in September.
All three of the U.S.-based casino giants last week reported first-quarter earnings helped by strength from Macau and Las Vegas operations.
