The IPO market has been pretty slow for the past two years due to the effects of a subprime mortgage crisis that turned into a credit crisis that turned into a worldwide financial crisis and recession. Nonetheless, two companies made their debuts Thursday -- one on the NYSE (NYSE: NYX), the other on the NASDAQ -- and they nailed it. Hyatt Hotels (NYSE: H) gave its investors a 12% gain on its first Big Board trading day, and Ancestry.com (NASDAQ: ACOM) switched those digits, jumping 21% in its first day of trading.

Hyatt Hotels overcame two major concerns. The worldwide travel market slump has been tough on hotel companies, and Hyatt has been subject to the same forces as everyone else. Also, investors may have been worried about infighting among the founder's heirs (the Pritzker family), but the double-digit price increase suggests that investors don't foresee Bancroft-style squabbles screwing investors -- or, if you don't like Dow Jones, now a part of News Corp (NASDAQ: NWS), Playboy (NYSE: PLA) makes the same point.

Las Vegas Sands (NYSE: LVS) volatility Elevated into Macao Resort Hotel opening. LVS opened the Venetian Macao Resort Hotel today. Sheldon Adelson, chairman & chief executive officer, said "it is no overstatement to say that the opening of Venetian Macao represents a massive paradigm shift for Macao and the future of tourism development in Asia." Goldman Sachs (NYSE: GS) says "the scale is enormous and the detail impressive." LVS over all option implied volatility of 44 is above its 26-week average of 39 according to Track Data, suggesting larger price fluctuations.

Ameristar Casinos (NASDAQ: ASCA) implied volatility Elevated at 43. ASCA, a Las Vegas based gaming and Entertainment Company, is recently down $0.55 to $28.39. ASCA has a market cap of $1.6 billion with long term debt of $878 million. ACSA over all option implied volatility of 43 is above its 26-week average of 37 according to Track Data, suggesting larger price risks.
