NEW YORK (CNNMoney) -- Stocks in disaster-stricken Japan capped a turbulent week with solid gains Friday after finance ministers from the Group of Seven nations announced a coordinated intervention in the currency market to prevent the yen from rising further.
The Nikkei 225 index, the most prominent measure of stocks traded in Tokyo, climbed 244 points, or 2.7%. For the week, the index was down 10.2%, but has rebounded 7% since suffering the third-worst drubbing in its history on Tuesday.
