Most stocks at 10% dividend or more are either in trouble or else they finance regular business operation with short-term debt that continuously rolls-over. In the second case a rise in short-term interest rates decreases margins.
Most stocks at 5% dividend or so, have significant long-term debt and even pension obligations. These companies are often routinely profitable but fundamentals can improve even more down around 3% dividends. For instance the higher dividend could be due to a declining stock price.
In any case look at the debt-to-equity ratio, the P/E ratio, and the dividend all together. Of course consider the business model.
