A healthy company is issuing stock for the right reason...acquisition. This portends good things for the future especially for dividend growth. If you are a long term investor you're in good shape. If you are short term you probably should have sold today.
An healthy company will not go through stock offering to create fund for future acquisitions in these low interest environment. They can finance at 3-4% interest ,as many good reits are doing. While in this proposed offering the company will pay 6% div. plus at least 10% offering expenses.
If the company is in a good shape why insiders are selling? A big chuck of the offering is COB dumping his stocks. By the way Obama Care will not be friendly to healthcare provider,that indirectly will effect healthcare reits
