NEW YORK (TheStreet) -- Shares of MGIC Investment (MTG - Get Report) are jumping 8.86% to $6.95 on heavy trading volume midday Tuesday after the company posted earnings and revenue that were above analysts' expectations.

Before today's market open, the Milwaukee-based mortgage insurance firm reported earnings of 26 cents per diluted share, surpassing analysts' estimates of 20 cents per share.

"I am pleased to report that our insurance in force continued to grow as we added $12.6 billion of high quality new insurance," CEO Patrick Sinks said in a statement.

"The delinquent inventory continued to decline while newer books of business continue to generate low level of new delinquent notices, and we maintained our traditionally low expense ratio," he added.

About 17.87 million of the company's shares changed hands so far today vs. its average 30-day volume of 7.3 million shares per day.

Separately, TheStreet Ratings Team has a "Hold" rating with a score of C on the stock.

The primary factors that have impacted the rating are mixed. The company's strengths can be seen in multiple areas, such as its notable return on equity, attractive valuation levels and expanding profit margins.

But the team also finds weaknesses including unimpressive growth in net income, weak operating cash flow and a generally disappointing performance in the stock itself.
