For example, while the S&P 500 index has fallen 9% year to date on news of increasing inflation and economic turmoil related to Russia's invasion of Ukraine, Aflac's stock has actually risen 5% so far in 2022. Despite Aflac's recent strong price performance, the stock is still a buy for investors seeking stability in a market currently fraught with uncertainty. While revenue was pressured in the fourth quarter, Aflac's profitability held strong due to fewer claims resulting from the effects of the pandemic.
