Kevin Turner, Microsoft Executive, to Join Citadel Securities
JULY 7, 2016 |- The New York Times| by NICK WINGFIELD and ALEXANDRA STEVENSON.

A top Microsoft executive, Kevin Turner, is leaving the company to join Citadel Securities as its new chief executive, continuing a wave of executive departures of technology industry leaders to financial firms.

Mr. Turner, Microsoft’s chief operating officer, oversaw Microsoft’s large sales organization, but Microsoft said he would not be replaced. .....Several prominent Silicon Valley executives have been hired by hedge funds in recent years. Bridgewater Associates, the world’s biggest hedge fund, hired a former senior Apple executive, Jonathan J. Rubinstein, this year. Mr. Rubenstein, who earned the nickname “the Podfather” for his work leading Apple’s iPod team, joined Bridgewater as co-chief executive in May.

And Two Sigma Investments, a quantitative hedge fund based in New York, hired Alfred Spector, a senior executive at Google, to be chief technology officer last year.

Citadel Securities is owned by the billionaire Kenneth C. Griffin, who also founded a $25 billion hedge fund called Citadel. Mr. Griffin founded the hedge fund 25 years ago as a young graduate after successfully trading bonds out of his Harvard dorm.

In recent years, Mr. Griffin has made a big push into market, making and electronic trading with Citadel Securities, disrupting a business that was once the domain of banks. It also claims to have 35 percent share of daily retail stock trading in the United States.

Hedge-Fund Managers Playing Larger Role in Art Market - WSJ.com

Hedge-fund managers, who play a vital but disruptive role in the broader financial markets, are increasingly throwing their weight around the art market: They are paying record sums to drive up values for their favorite artists, dumping artists who don't pay off and offsetting their heavy wagers on untested contemporary art by buying the reliable antiquity or two. Aggressive, efficient and armed with up-to-the-minute market intelligence supplied by well-paid art advisers, these collectors are shaking up the way business gets done in the genteel art world.....Today, are applying their day-job tactics to their art shopping, dealers say.

Corporate raiders a generation ago typically held their art purchases for at least a decade. Today, the average holding period for contemporary art is two years, according to a former Sotheby's specialist. That is enough time to reap a tidy profit on a rising-star artist but hardly enough for art history to rule on the artist's lasting merits.

FT 20100210 - Business books - Maths geniuses’ models did not add up
At their peak, quantitative traders were a force with which to be reckoned. Between them they controlled about $150bn (€109bn, £96bn) and, because many used lots of borrowed money as well, they collectively had assets of as much as $1,000bn. But many of them were then crushed in the market meltdown, having failed to factor in just how vulnerable their models were. “Even as the mortgage market imploded, quant funds such as AQR, Renaissance, Saba [Weinstein’s group at Deutsche] and Citadel believed they were immune to the trouble,” Patterson writes, “either because they didn’t dabble in subprime or because they believed they were the smart guys in the room and had either hedged against losses or were on the right side of the trade and were poised to cash in.” The whizzes who studied market relationships so exhaustively failed to grasp some elementary truths, such as that distress in one market can lead to selling in an entirely different and hitherto unrelated market.
