Shares in Wynn Macau Ltd., a unit of Wynn Resorts founded by Steve Wynn, soared to a one-month high. This was a day after the casino operator posted quarterly results that beat analysts' expectations.

The casino operator, boosted by a strong economy and strict cost controls, reported a near doubling of fourth-quarter earnings before interest, taxes, amortization and depreciation on Thursday to $142 million, exceeding JPMorgan's expectations by 4 percent.

Billy Ng, an analyst with JPMorgan, commented on the impressive figure, saying, "The fourth-quarter results are very solid".

"The outlook should be good. They are the only ones expanding and putting in capacity in 2010. They should gain some market share. The bigger question is how the overall market is doing, with the tightening of liquidity from China. There will be some impact, but it will be limited", he stated.

Wynn Macau laid stress that "Encore", the extension of its current casino resort in Macau, will open by April.

The project is expected to cost about $600 million, the firm said.
