The article points out that in the event of a potential 10%-20% market correction, "Dividend King" companies, those that have increased dividends for 50 consecutive years or more, are investment targets worth considering. Among them, S&P Global (SPGI) stands out with a conservative payout ratio of 20%-30% and a strong economic moat; ABM Industries (ABM) has a low payout ratio of 31%, providing a buffer during economic downturns; National Fuel Gas (NFG), as a diversified energy company, has a lower forward P/E ratio among "Dividend Kings" and has received a "Buy" rating and a $107 price target from Bank of America.
