Looking for income? These dividend stocks have high yields that seem well supported.

The search for income continues to be a challenge for investors in today's low-yield environment. A screen of the S&P 500 for high dividend yields that are expected to be well covered by the companies' free cash flow has yielded a list of 11 stocks, including Ford, Pfizer, and Verizon. These companies have high dividend yields, but what's more important is that their free cash flow appears sufficient to support these payouts.

This is significant because dividend sustainability is a key concern for income-focused investors. When a company's dividend yield is high, it's natural to wonder whether the payout is likely to be maintained or if it's a sign of distress. By focusing on stocks with high yields that are supported by free cash flow, investors can gain some confidence that the dividend payments are more likely to be sustained. In the case of Ford, Pfizer, and Verizon, these companies have a track record of generating cash and have made commitments to return capital to shareholders through dividends.

To watch next: earnings reports from these companies to see if their free cash flow remains on track to support their dividend payments. Also, keep an eye on interest rates, as changes in the broader market can impact the attractiveness of dividend-paying stocks relative to other income-generating assets. If interest rates rise, for example, investors may demand higher yields from dividend stocks, which could impact the prices of these shares. Conversely, if interest rates remain low, dividend-paying stocks like Ford, Pfizer, and Verizon may continue to attract investors seeking income.
