Health care and medial office REIT HCP ( HCP) has had a strong year -- while shares are up approximately 11% in the trailing 12 months, that number slingshots to around 15% when the firm's hefty dividend payout is factored in. And those returns are only getting higher. HCP announced a 4.17% dividend increase last week, bringing its quarterly distribution to a 4.86% yield at current prices. HCP owns a real estate portfolio that's spread throughout five different segments: senior housing, skilled nursing, medial offices, lab space, and hospitals. That diversified tenant base means that leases are less likely to be adversely impacted by a major industry headwind, like healthcare legislation. At the same time, this REIT's financial structure means that it's a strong example of an income-generation instrument rather than a direct play on the real estate market - investors should be fans of that fact. While REITs' legal income distribution requirements often leave them with relatively light capital backstops, HCP is in solid financial shape. That stability should help to secure the firm's large dividend payout, particularly when coupled with its diversified health care positioning.
