Temasek CEO Ho Ching rose to prominence a few years ago when the sovereign wealth fund she runs began to invest heavily in banks and financial services firms such as ICICI, Bank of China, Merrill Lynch, Barclays, and Standard Chartered. When the global financial crisis hit she moved to reduce exposure to the developed world, and last year the market value of the portfolio rose 42%, a new year-end high. Lately she has been looking to make direct investments in Asia blue chips. Ho Ching consistently ranks high on several publications' lists -- including Fortune's -- of the most powerful women in business.
