Hedge fund nearly doubles Delek stake

NY firm manages nearly $5B

A $4.7 billion hedge fund manager run by a disciple of legendary investor Julian Robertson has in recent weeks substantially increased its stake in Delek US Holdings, becoming the second outside investor to own at least 5 percent of the local company.

New York-based Steadfast Capital Management on Monday filed papers with the Securities and Exchange Commission saying it owned 3.7 million shares of Delek as of June 25. That amounted to 6.2 percent of Brentwood-based Delek, which runs refineries in Texas and Arkansas and owns the Mapco chain of gas stations, and was up from just 1.9 million shares at the end of March.

Steadfast is run by Robert Pitts Jr., one of the dozens of so-called Tiger Cubs who made their mark at Robertson's Tiger Management before striking out on their own. The firm's disclosure of its recent purchases — view the filing here — come on the heels of the latest big sale of Delek US stock by Israel-based Delek Group, which has over the past year cut its stake to less than 8 percent from 30 percent.

By our count, Steadfast and fellow hedge fund Point72 Asset Management are now the second- and third-largest shareholders of Delek US, shares of which (Ticker: DK) are flat over the past three months. Around noon Tuesday, they were up slightly to $29.05.
