A look at some of the movers
Genworth Financial rose last week after it raised $564 million in capital via a secondary offering. In this environment, the ability to raise capital isn't a given.

Last week, Kodak cut a deal with private equity firm Kohlberg, Kravis Roberts (KKR), which will buy $400 million of Kodak's bonds. As part of the deal, Kodak has agreed to give KKR warrants to buy up to 53 million shares. In addition, the company said it would offer $300 million in convertible bonds. The price of both actions highlight the company's rickety capital position -- combined, the capital raises could dilute shares up to 35% to 40%.
