Israeli holding company Delek Group Ltd. (DLEKG.TV) said Thursday its net profit for the second quarter totaled 101 million shekels ($28.4 million), up from ILS64 million in the second quarter of 2010, mainly due to capital gains and an improved performance by its American subsidiary, Delek US Holdings Inc. (DK.NYSE).

Total revenue rose 60% to ILS14 billion. Delek Group saw a capital gain of ILS348 million in the quarter from selling shares in Noble Energy Inc. (NBL.NYSE). Delek US Holdings also contributed to the higher net profit because of higher margins.

Delek Group has holdings and investments in energy, real estate and the automotive sector.

At 1130 GMT, shares of Delek were down ILS3.90, or 0.61%, at ILS636.00, in a lower Tel Aviv market.
