Private equity, in my opinion, is the juiciest of all the financial sectors. While venture capital is more baldly a gamble -- after all, something like 10% of investments actually pay out handsomely -- private equity is a quieter, stuffier, much, much larger gamble. It makes my blood gurgle with excitement.

Private equity firms have been gambling big, of late, and, according to the Wall Street Journal [subscription required] at this wee hour of the morning, they might do even more so by orchestrating an LBO of Harrah's Entertainment, Inc. (NYSE:HET). Naturally, the biggie of all private equity gamblers, Texas Pacific Group, is rumored to be involved in the talks to buy out Harrah's, which has a $12.34 billion market value and $10.2 billion in debt. Now there's some leverage.

While this would certainly be the biggest casino company ever bought out by a private equity group, it wouldn't be the first casino company -- Colony Capital, also rumored to be in on discussions, has bought several properties in Atlantic City and Las Vegas -- or the first huge gamble. After all, there's HCA Inc. ($21.3 billion), in my mind (and I was analyst on many a hospital deal in my time in investment banking) a huge hospital management company like HCA is a huge gamble. In hospitals you have two very egocentric, impossible-to-predict, and money-hungry groups pulling your cash flow this way and that: doctors and the U.S. government. Ick.
