MANILA, Philippines (Xinhua) - Foreign portfolio investments, also known as "hot money," in the Philippines rose to $586 million in January, the central bank said today.

January's net inflow is four times more than the net inflow in December and nearly three times more than the amount recorded in January last year.

Most of the investments went to Philippine Stock Exchange- listed securities, with a net inflow at $385 million.

Year-on-year, registered investments and outflows were lower compared to last year as investors remained cautious due to renewed worries over Greece's debt problems, and the International Monetary Fund's cut in growth outlook.

Singapore, the United Kingdom, the United States, Luxembourg and China's Hong Kong remained in the list of top five investor countries and regions.
