You can start your screen by finding stocks that meet the following condition:
PE < Dividend Yield + Earnings Growth Rate
Note:
You can use Yahoo Finance's Analysis section to find projected earnings for the company's current year and for the following year. You may want to find how accurate historically analysts' earnings estimates are versus actual reported earnings, then make adjustments accordingly.
Second step:
Check the selected companies' financial metrics, for example, rising incomes, positive free cash flows that are able to cover the dividends, etc. All these can be found at Yahoo Finance's Financials section, or at the company's latest SEC filings (e.g. 10K-annual report) at www.SEC.gov.
Note: Yahoo Finance often picks up "adjusted" earnings, which may exclude a laundry list of supposedly one-time items, sometime these items are legitimate, sometimes they maybe excuses by the management for not doing better. Sometime it's worthwhile to visit previous 10-Ks to find out if such "one-time" adjustments were consistently done in the past and threw out costs that are regular part of business.
