Stockholders' Equity Note Disclosure [Text Block] | Capital Stock Share Repurchase Program On August 9, 2017, Radian Group’s board of directors renewed the Company’s share repurchase program, authorizing the Company to repurchase up to $50 million of its common stock. The program authorized the Company to repurchase Radian Group common stock in the open market or in privately negotiated transactions, based on market and business conditions, stock price and other factors. Pursuant to a trading plan under Rule 10b5-1 of the Exchange Act, during the three and six months ended June 30, 2018, the Company purchased 2,491,843 and 3,022,856 shares, respectively, at an average price of $16.07 and $16.56 per share, respectively, including commissions. At June 30, 2018, there was no remaining purchase authority under this program. Other Purchases We may purchase shares on the open market to settle stock options exercised by employees and purchases under our Employee Stock Purchase Plan. In addition, upon the vesting of certain restricted stock awards or the auto-exercise of certain expiring stock options under our equity compensation plans, we may withhold from such vested or auto-exercised awards shares of our common stock to satisfy the tax liability and the stock option cost of the award recipients, as applicable.
