From IBD:
When it comes to income stocks, the steadier the dividend payout, the better. IBD measures how stable a company’s dividend history is over a five-year period with the Dividend Stability Factor, which ranges from 0 (most stable) to 99 (most volatile). Four stocks in the Dividend Leaders screen score a 0 and also offer payouts well above the S&P 500’s average 1.92% yield.
