Genworth Financial's

(GNW) - Get Report

stock sale this week has created a buying opportunity for investors willing to take a chance on a volatile stock from a downtrodden industry.

On Tuesday, Genworth said it raised $564 million by issuing 48 million shares for $11.75 each. The sale diluted the value of the company's shares outstanding by 10%, but it made an already cheap stock even more appealing. The shares are trading for 57% of book value, compared to 104% for the industry.

at an industry conference yesterday, it appears the mood for insurers is changing. Genworth could break even this year, according to analyst estimates. If the markets improve, we could see a significant swing for this stock.

There's almost no short interest in Genworth, which reflects investors' confidence that the shares will rise. The stock has more than doubled in the past three months, but it's down 15% from a year ago, when the markets began to spiral. Genworth shares have been highly volatile with a beta of 2.78.

In June, rival

(LNC) - Get Report

raised $690 million by issuing shares for $15 each. The shares have since climbed to $27. Lincoln stock has a price-to-book value of 90%, and is still a good opportunity.
