NEW YORK ( TheStreet) -- Teekay Corp (NYSE: TK) has been upgraded by TheStreet Ratings from hold to buy. The company's strengths can be seen in multiple areas, such as its solid stock price performance, increase in net income, expanding profit margins and growth in earnings per share. We feel these strengths outweigh the fact that the company has had generally poor debt management on most measures that we evaluated. Teekay Corporation provides crude oil and petroleum product transportation services in Bermuda and internationally. The company has a P/E ratio of 15.5, below the S&P 500 P/E ratio of 22.6. Teekay has a market cap of $2.6 billion and is part of the services sector and transportation industry. Shares are up 5.8% year to date as of the close of trading on Thursday.
