DUBAI — Mark Mobius, one of the world's best-known emerging market investors, will increase his exposure to Saudi Arabia once the Kingdom opens its markets to foreigners. Saudi Arabia has been considering a wider opening of its market for several years; currently foreigners have only very limited opportunities to invest through indirect ownership and exchange traded funds. “Right now, we don't have much in Saudi Arabia as the current system opens us up to counterparty risks. Once the market is fully open, we probably will increase our exposure, provided all things remain equal,” Mobius, executive chairman of Franklin Templeton's emerging markets group, said in a telephone interview as part of Reuters' Middle East Investment Summit. With the Gulf state rolling out a $400 billion infrastructure program - the world's biggest stimulus relative to GDP - foreigners are keen on the Saudi stock market and the biggest Arab economy. The bourse has risen 5.4 percent year-to-date, compared with a 6.2 percent rise for MSCI's emerging market index. Saudi's opening of its stock market to foreigners will be gradual, its capital markets regulator has said, although it has not given a date. Analysts and traders expect the move to come next year. Mobius, who helps oversee $48.2 billion in emerging market funds, expects the opening up of the Saudi exchange to have wider benefits as the event will drive a wave of foreign investment into the Middle East. Saudi Arabia currently ranks sixth in country weightage for Templeton's $1.1 billion Frontier Markets Fund, lagging behind Nigeria, Kazakhstan, Vietnam and its Gulf peers, Qatar and United Arab Emirates. The fund manager said institutional investors are increasingly buying into the idea of investing in frontier markets - regions seen as riskier and less developed than emerging markets - in the current low interest rate environment and at a time of low growth in developed markets. “We now have $2 billion in frontier markets which means that there is a group out there which is interested in generating real alpha,” he said. The excess return of a fund relative to the return of the benchmark index is a fund's alpha. Mobius is bullish on banking, oil and gas, mining and consumer-related stocks within the frontier space. Political uprisings in the region during 2011 will have a positive impact in the long-term, Mobius said. — Reuters
