"If you look at any asset price you have to be thinking, this is highly dubious to be a sustainable price." -Paul Tudor Jones (Trades, Portfolio)

Investing legend Paul Tudor Jones (Trades, Portfolio) talked with Goldman Sachs (GS) CEO Lloyd Blankfein last week. He not only discussed his non-profit efforts, but also the state of the market.

For many years, Leucadia (LUK) was basically a mini-Berkshire Hathaway (BRK.A)(BRK.B). Its shares doubled in value every few years for decades. Like many great companies, its growth has peaked, at least for now.

The company has 362.6 million shares and trades at $19.36 ($7 billion). The stock pays a 1.31% dividend yield. Tangible book value is $7.5 billion at the end of the second quarter. There's no use in looking at earnings and cash flows as it is a holding company. No use in valuation that is. It is useful in knowing cash flows to support debt.

Dear Fellow Shareholders,

We thought 2015 would be a pretty good year for Leucadia (LUK), but beginning in August, a tsunami of market volatility struck land and damaged the results of Jefferies’ Fixed Income businesses and, more recently, Jefferies’ Equities and Investment Banking efforts, as well as our Leucadia Asset Management platform. We were not unprepared, having decided last year to exit the Bache futures and commodities business, and later in 2015, determined to reduce the size of Jefferies’ balance sheet, debt and risk appetite, as well as make some other targeted changes in its business model. Notwithstanding these actions,

Leucadia National Corp (LUK), a New York-based investment company, is often called a “baby Berkshire Hathaway” (BRK.A)(BRK.B) for the extensive variety of its holdings for others – mining and drilling, telecommunications, healthcare, manufacturing, real estate and banking and lending, among others.

That was primarily former CEO Ian Cumming’s doing. Initially, his approach was to invest in dozens of companies, most of which could be characterized as struggling, then built them up and sold them. In 2009 and 2010, Leucadia enjoyed returns in excess of 59%.

That is sure to make the clients happy, but Leucadia may have

Guru Ian Cumming (Trades, Portfolio), founder of Leucadia National (LUK), a New York-based holding company, tends to be low-key in his personal stock dealings. He hasn’t had more than two large transactions in a quarter in three years, and the third quarter of 2014 was no exception.

Well, it was an exception in one regard – whether he deals in one stock or several, Cumming frequently buys or sells in numbers that can be expressed in millions or tens of millions. Sometimes, though, as was the case in the third quarter, his deals involve
