Nanex ~ 04-May-2012 ~ UOIL Wild quotes

Looking at quotes on the stock symbol UOIL (an oil related ETF) makes us wonder who in their right mind would allow this.

If you wanted to buy this "stock", the price could change from $48 to $73. Suddenly.  For no economic reason whatsoever.

And it does this every few seconds.

There are exactly zero trades during the 90 minutes shown in the charts below. Probably for good reason.
