The QIA has emerged as one of the world's most assertive investors since it was founded by the Gulf state in 2005 with a mandate to use the country's gas riches to invest in a diversified portfolio of long-term holdings.
Other core holdings losing ground since July 1 are in Royal Dutch Shell (down about $500 million), Barclays ($240 million) and Siemens ($310 million). Just one of the top 10 stakes had a positive quarter — Vinci, the French construction company, up about $200 million — while Iberdrola, the Spanish utility, was flat.

The rocky quarter comes as the Doha-based fund — the ninth biggest in the world by total assets, according to SWFI estimates — opens its first office in the US. The fund, which has invested about $7 billion in the US to date, is now aiming to do five times as much over the next five years, principally in the infrastructure, technology and real estate sectors, according to people familiar with its plans.
