A few weeks back, Robb Report launched a Luxury Travel Index to track the ups and downs of public companies peddling luxury goods. The goal is to have an index that shows the overall strength of this loosely defined industry, which doesn’t fit into one segment such as fashion, travel, real estate, or jewelry. So who qualifies?

“Global brand names among the index constituents are luxury houses such as LVMH, Richemont and PPR; fashion companies Hermes, Burberry, and Ralph Lauren; financial services providers UBS, Goldman Sachs and Credit Suisse; retailers Saks and Nordstrom; jewelers Tiffany & Co. and Harry Winston; airplane manufacturers Dassault and Embraer-Empresa; liquor companies Remy Cointreau and Pernod Ricard; auto companies Porsche, Daimler Chrysler and BMW; and lodging concerns Starwood and Mandarin Oriental.”

The index launched right before the worldwide wild stock market ride of the past few weeks, but it has been amazingly consistent so far. Trading under the symbol ROB on the NYSE, it has so far only ranged from 23.50 to 25.00 a share. It’s quite thinly traded right now though, so who knows if this trend will continue.
