Best of StockTwits: Investors in a $TIF

Tiffany (TIF) is showing that diamonds are not an investor's best friend. And eBay's (EBAY) deal to get PayPal to be used on VeriFone Systems (PAY) cash registers gets little love from traders.

etfhack: @Retail_Guru $TIF inventories up 27%? how can this not bode horribly for margins in back 1/2 of yr?

firstadopter: $TIF PR: "Americas region underperformed, continuing a soft trend that began in the last quarter of 2011" Wow they blaming U.S. not Europe?

gtlackey: $TIF could reason US slowed more be less Foreign travel to US for "shopping" since Euro-mess and stronger $DX_F?

There is no glossing over how bad the Tiffany guidance is. But as I pointed out earlier this morning, it looks like Signet (SIG) is expecting a tough quarter as well. So yes, luxury retailers in the U.S. may be feeling a pinch because of a sleepy economy here .. in addition to slowdowns around the rest of the world.

biggercapital: Owning $EBAY feels like showing up at a rodeo on the back of a turtle

Ha! It is curious that neither eBay nor VeriFone rose on this news. As for the taking the turtle to a rodeo? Just pull a line from former PayPal -- and now also former Yahoo (YHOO) -- head Scott Thompson. Pretend that you are really riding a horse ... even if you don't have one.
