So long as LDR has the earnings to support its ever increasing dividend, it is a core stock for any conservative investor. It has a huge moat, with no visible competitor in the radiation monitoring business. As long as ionizing radiation is used in medical diagnosis and therapy and so long as the company takes on no other unconnected ventures, valuation for this company is rock solid. Every time its dividend exceeds 3.5%, a buying opportunity exists (as now at 3.8%). I've owned this stock for 17 years and continue to purchase more at opportune moments. It is not and never will be a high growth company, but its dividend just keeps increasing.
