Most investors don't keep tabs on their companies' fundamental values. That's a mistake. If you take the time to read past the headlines and crack a filing now and then, you're in a much better position to spot potential trouble early. Better yet, you'll improve your odds of finding the underappreciated home run stocks that provide the market's best returns.

We can help you keep tabs on your companies with MyWatchlist.com, our free, personalized stock-tracking service. Here are three dividend stocks for your watchlist.

1. LINN Energy (Nasdaq: LINE)
LINN Energy is an MLP focused on maximizing cash flows from its portfolio of oil and natural gas assets with proved reserves consisting of 36% oil, 48% natural gas, and 16% natural gas liquids. Through an acquisition, Linn recently entered into the Bakken shale area. With a dividend yield of 8.3%, LINN has a comparable yield to competitor Encore Energy Partners LP (NYSE: ENP) at 8.4% and a larger yield than competitor Legacy Reserves (Nasdaq: LGCY) at 6.5%. I like LINN Energy better than its competition as its dividend yield is higher and the company trades at a lower price-to-book ratio.

2. CAPS' Weekly Top Stock Idea: Government Properties Income Trust (NYSE: GOV)
Each week, I cull a top stock idea from the pitches on CAPS, The Motley Fool's 170,000-member free investing community. Government Properties Income Trust, a pick from June, caught my eye when it recently raised its quarterly dividend to $0.42 per share for a yield of 6.3%. Government Properties is a REIT focused on the office market. Click here to see the pitch selected for CAPS' weekly top stock idea.

3. MV Oil Trust (NYSE: MVO)
MV Oil Trust has nearly 1,000 oil and natural gas wells in Kansas and Colorado. The company recently announced its upcoming distribution will be $0.82, for a trailing-12-month yield of 7.2%, high enough to keep the firm on the list of the highest-yielding royalty trusts. MV Oil Trust has a higher yield than competitors Penn West Petroleum (NYSE: PWE) at 3.9% and EV Energy Partners (Nasdaq: EVEP) with a yield of 5.4%. I like MV Oil Trust better than its competition for its high yield and exposure to rising oil prices as 98% of its proved reserves are made up of oil.
